HDAP API reference

HDAP APIs offer HTTP access to directory data as JSON resources. DS software maps JSON resources to LDAP entries.

Examples in this documentation depend on features activated in the ds-evaluation setup profile. For details, refer to Learn about the evaluation setup profile.

The code samples demonstrate how to contact the server over HTTPS using the deployment CA certificate. Before trying the samples, generate the CA certificate in PEM format from the server deployment ID and password:

$ dskeymgr \
 export-ca-cert \
 --deploymentId $DEPLOYMENT_ID \
 --deploymentIdPassword password \
 --outputFile ca-cert.pem

Authentication

Anonymous

When you perform an operation without authenticating, HDAP responds like LDAP would:

If DS access control lets anonymous users perform the operation, the operation returns the expected result.

For example, the ds-evaluation profile lets anonymous users read and search many attributes.
If anonymous users can’t perform the operation, HDAP returns HTTP 401 Unauthorized.

HTTP status code 401 means the user must authenticate.

Basic auth

HDAP supports HTTP Basic authorization with the _id of resource as the HTTP username. The _id matches the suffix of the path to the resource. For example, when you set up DS with the ds-evaluation profile, Babs Jensen’s _id is dc=com/dc=example/ou=People/uid=bjensen.

Use HTTPS to avoid sending the password over an insecure connection.

Bearer auth

HDAP supports HTTP Bearer authorization using an access token. The access token is a JSON Web Token (JWT) DS returns for a successful authentication action.

Using a JWT bearer token for authorization means DS only has to authenticate the user once during the lifetime of the token.

This is especially good when performing multiple operations as a user with a strong password storage scheme. The computational cost to validate the password is high, but you only pay the cost once. The cost to validate a JWT token is low for each subsequent operation.

Use HTTPS POST to the path for the account to authenticate with _action=authenticate in the query string and a JSON object { "password": "<password>" } as the request payload.

On success, the HTTP status code is 200 OK, and the response body is a JSON resource with an access_token. Use the bearer token to authorize subsequent HTTP requests:

Curl
JavaScript
Python
Ruby

HTTP Bearer authorization

$ curl \
 --request POST \
 --header 'Content-Type: application/json' \
 --data '{ "password": "hifalutin" }' \
 --cacert ca-cert.pem \

Resources

HDAP resources are JSON objects whose top-level elements are fields with string identifiers; for example:

{
  "_id" : "dc=com/dc=example/ou=People/uid=user.0",
  "_rev" : "0d3ce3bf-4107-3b34-9e5a-fa71deb8b504",
  "objectClass" : [ "top", "person", "organizationalPerson", "inetOrgPerson" ],
  "cn" : [ "Aaccf Amar" ],
  "description" : [ "This is the description for Aaccf Amar." ],
  "employeeNumber" : "0",
  "givenName" : [ "Aaccf" ],
  "homePhone" : [ "+1 720 204 9090" ],
  "initials" : [ "AAA" ],
  "l" : [ "Harrisonburg" ],
  "mail" : [ "user.0@example.com" ],
  "mobile" : [ "+1 412 030 0042" ],
  "pager" : [ "+1 439 180 6470" ],
  "postalAddress" : [ "Aaccf Amar$31206 Spring Street$Harrisonburg, IL  04284" ],
  "postalCode" : [ "04284" ],
  "sn" : [ "Amar" ],
  "st" : [ "IL" ],
  "street" : [ "31206 Spring Street" ],
  "telephoneNumber" : [ "+1 485 381 2060" ],
  "uid" : [ "user.0" ]
}

HDAP resources have the following special fields:

_id

Unique identifier.

The resource _id matches the trailing components of its path. For example, the resource at /hdap/dc=com/dc=example/ou=People/uid=bjensen has "_id":"dc=com/dc=example/ou=People/uid=bjensen".

The path elements of an _id are URL path-encoded RDN strings. When you create a resource:

Percent-encode each path element.
If the path element includes characters to escape in LDAP, " # + , ; < = > \, escape those characters in the LDAP RDN string before percent-encoding the result for HDAP.

CN value LDAP RDN HDAP path element

CN value	LDAP RDN	HDAP path element
`Babs Jensen`	`cn=Babs Jensen`	`cn=Babs%20Jensen`
`Babs/Jensen`	`cn=Babs/Jensen`	`cn=Babs%2FJensen`
`Babs\Jensen`	`cn=Babs\\Jensen`	`cn=Babs%5C%5CJensen`

cn=Babs%5C2Jensen

_rev

The resource revision.

HDAP versions individual resources with revision numbers corresponding to the LDAP ETag operational attribute. HDAP uses the If-Match: <revision> header to determine whether to apply changes to a resource.

The other JSON fields have the same names as the LDAP attributes they represent.

Fields

Multivalued LDAP attributes correspond to arrays in JSON. Unlike arrays in JavaScript, these arrays have set semantics. No duplicates are allowed and the element order is arbitrary.

By default, HDAP behaves like a normal LDAP client application, returning JSON fields for all non-empty LDAP user attributes.

To return JSON fields for operational LDAP attributes, request them specifically with the _fields parameter.

Use +, which encodes to %2B, to return fields for all operational attributes.
To return empty fields, set the advanced HDAP endpoint configuration property return-null-for-missing-properties:true.

With the feature enabled, HDAP returns empty single-valued fields as null and empty multivalued fields as [], except for password fields, which HDAP returns as an array even if they are constrained to being single-valued.

ACI deny rules can cause misleading results, where although an "empty" attribute is set you cannot read it. Check the applicable ACIs when HDAP does not return an expected field.

Values

HDAP derives its resource field values from LDAP attribute values based on the attribute syntax.

¹ JSON strings are enclosed in double quotes, so double quotes are escaped with a backslash \".

² DS supports more subtree specification features than demonstrated in this simple example. For complex subtree specifications, add an example from LDIF, read the resource, and review the resulting JSON.

Schema

HDAP provides two ways to read JSON schema for resources:

Read the schema for an existing resource or a resource to create with the schema action.

Read the schema for an individual field or object class directly.

The fields map to LDAP attribute types. A resource’s objectClass values map to LDAP object classes.

To read the schema for Use

To read the schema for	Use
An individual field.	HTTP GET on `schemas/attributeTypes/type`. Example: `GET /hdap/schemas/attributeTypes/cn HTTP/1.1 Host: example.com Accept: application/json`
An object class.	HTTP GET on `schemas/objectClasses/class`. Example: `GET /hdap/schemas/objectClasses/person HTTP/1.1 Host: example.com Accept: application/json`

An individual field.

HTTP GET on schemas/attributeTypes/type.

Example:

GET /hdap/schemas/attributeTypes/cn HTTP/1.1
Host: example.com
Accept: application/json

An object class.

HTTP GET on schemas/objectClasses/class.

Example:

GET /hdap/schemas/objectClasses/person HTTP/1.1
Host: example.com
Accept: application/json

Operations

HDAP APIs support the following operations:

HDAP operation	Description	HTTP method
Create	Add a new resource	PUT or POST
Read	Retrieve a single resource	GET
Update	Replace content in an existing resource	PUT
Delete	Remove an existing resource	DELETE
Patch	Modify an existing resource	PATCH

Create

Use either HTTP POST or HTTP PUT.

Use HTTP POST with the query string parameter _action=create and the JSON resource as a payload. Accept a JSON response. HDAP builds the _id using the parent resource path and the field in the resource corresponding to the LDAP RDN:

POST /hdap/dc=com/dc=example/ou=People?_action=create HTTP/1.1
Host: example.com
Accept: application/json
Content-Length: ...
Content-Type: application/json
{ JSON resource }

Use HTTP PUT with the _id in the resource and the URL path. Use the If-None-Match: * header. Accept a JSON response:

PUT /hdap/dc=com/dc=example/ou=People/uid=newuser HTTP/1.1
Host: example.com
Accept: application/json
Content-Length: ...
Content-Type: application/json
If-None-Match: *
{ JSON resource }

The response indicates the resource location in the Location header.

If you include the If-None-Match header, you must use If-None-Match: *. In this case, the request creates the object if it does not exist and fails if the object does exist.

If you include any value other If-None-Match: *, HDAP returns an HTTP 400 Bad Request error. For example, creating an object with If-None-Match: revision returns a bad request error.
If you do not include If-None-Match: *, the request creates the object if it does not exist and updates the object if it does exist.

Supported parameters:

_action=create
dryRun=true
_fields
manageDsaIT=true
passwordQualityAdvice=true
_prettyPrint=true
relax=true

For examples, refer to Create.

Read

Read a resource with HTTP GET and accept a JSON response:

GET /hdap/dc=com/dc=example/ou=People/uid=newuser HTTP/1.1
Host: example.com
Accept: application/json

Supported parameters:

_fields
manageDsaIT=true
_prettyPrint=true

For examples, refer to Read.

Update

Update a resource with HTTP PUT and the JSON resource as the payload. Accept a JSON response.

Unlike other Common REST applications, HDAP does not require the full JSON resource.

HDAP replaces the fields in the resource with the fields in the payload, operating like a patch Replace. Other fields retain their existing values.
Use the If-Match: _rev header to update the resource only if the revision matches.

Use If-Match: * to apply the update irrespective of the revision.

PUT /hdap/dc=com/dc=example/ou=People/uid=newuser HTTP/1.1
Host: example.com
Accept: application/json
Content-Length: ...
Content-Type: application/json
If-Match: _rev
{ JSON resource }

Supported parameters:

dryRun=true
_fields
manageDsaIT=true
passwordQualityAdvice=true
_prettyPrint=true
relax=true

For examples, refer to Update.

Delete

Use HTTP DELETE and accept a JSON response:

DELETE /hdap/dc=com/dc=example/ou=People/uid=newuser HTTP/1.1
Host: example.com
Accept: application/json

Supported parameters:

dryRun=true
_fields
manageDsaIT=true
_prettyPrint=true
subtreeDelete=true

For examples, refer to Delete.

Patch

Use HTTP PATCH request with a JSON array of patch objects appropriate to the operation. Each patch object in the payload can have these fields:

operation

HDAP supports these patch operations:

add
remove
replace
increment

HDAP does not support the common REST copy, move, or transform operations.

field: A JSON pointer to the target field
value: The value for the patch

The patch request has the following format:

PATCH /hdap/dc=com/dc=example/ou=People/uid=newuser HTTP/1.1
Host: example.com
Accept: application/json
Content-Length: ...
Content-Type: application/json
If-Match: _rev
[ JSON array of patch operations ]

Patch operations apply to these types of target fields:

Single-valued, such as an object, string, boolean, or number.
Set semantics array, where the elements are not ordered and duplicates are not allowed.

If you reference array values by index, HDAP returns an error.

Supported parameters:

dryRun=true
_fields
manageDsaIT=true
passwordQualityAdvice=true
_prettyPrint=true
relax=true

For examples, refer to Patch.

Add

Patch add ensures the target field contains the value provided, creating parent fields as necessary.

If the target field is single-valued and a value already exists, HDAP replaces the value with the value you provide.

HDAP does not return an error when adding a value to a single-valued field with an existing value.
If the target field is multivalued (an array), HDAP merges the array of values you provide with the existing values.

For arrays, HDAP adds new values and ignores duplicates.

Add a telephone number

[{
  "operation" : "add",
  "field" : "/telephoneNumber",
  "value" : "+1 408 555 1212"
}]

Remove

Patch remove ensures the target field does not contain the value provided.

If you do not provide a value and the target field exists, HDAP removes the entire field.
If you provide a value and the target field is single-valued, the value must match the existing value to remove; otherwise, HDAP does not change the field.
If the target field is multivalued, HDAP removes the values in the array you provide from the existing set of values.

Remove all telephone numbers

[{
  "operation" : "remove",
  "field" : "/telephoneNumber"
}]

Remove a specific telephone number

[{
  "operation" : "remove",
  "field" : "/telephoneNumber",
  "value" : "+1 408 555 1212"
}]

Replace

Patch replace removes existing values on the target field and replaces them with the values you provide. It is equivalent to a remove of the field followed by an add.

Reset the telephone number

[{
  "operation" : "replace",
  "field" : "/telephoneNumber",
  "value" : "+1 408 555 1212"
}]

Increment

Patch increment changes the value(s) in the target field by the amount you specify.

Use a positive number to increment or a negative number to decrement the value(s).
The target field must hold a number or a set of numbers.
The value you provide must be a single number.

Lower the temperature

[{
  "operation" : "increment",
  "field" : "/temperature",
  "value" : -2
}]

Action

Use HTTP POST with the _action parameter to request a predefined action.

_action=accountUsability: Determine whether the user can authenticate to the directory.
_action=create: Create a resource with HTTP POST.
_action=modifyPassword: Change your password.
_action=rename: Rename a resource, changing its _id.
_action=resetPassword: Change another user’s password.
_action=schema: Get the JSON schema for an object.

Supported parameters:

_action
deleteOldRdn=true (rename operation)
dryRun=true (create, password, and rename operations)
_fields
manageDsaIT=true (rename operation)
objectClasses (schema operation)
passwordQualityAdvice=true (password operations)
_prettyPrint=true
relax=true (rename operation)

The request and response depend on the action. For details, refer to Actions.

Query

Use HTTP GET with the _queryFilter parameter to list resources at or under a target resource and matching a query filter. Accept a JSON response.

GET /hdap/dc=com/dc=example/ou=People?_queryFilter=... HTTP/1.1
Host: example.com
Accept: application/json

HDAP returns the result as a JSON object including a results array. Other response fields depend on the parameters.

Supported parameters:

_countOnly=true
_fields
_pagedResultsCookie
_pageSize
_prettyPrint=true
_queryFilter
scope
_sortKeys
subentries=true
_totalPagedResultsPolicy

For examples, refer to Query.

Headers

In addition to the headers described for HDAP Operations, HDAP APIs support these Common REST headers.

Accept-API-Version

The Accept-API-Version header specifies protocol and resource versions:

Accept-API-Version: protocol=version,resource=version

protocol: The version reflects changes in the Common REST protocol, such as common method parameters and headers specified by the protocol itself, or the input or response conventions it prescribes.

For example, protocol version 2.2 introduced the _countOnly parameter.
resource: The version reflects changes in the resource implementation, including JSON representation of resources, input parameters required, and incompatible behavior changes.

For example, the version changes when errorMessage changes to message in a JSON response.

The Content-API-Version response header specifies the protocol and resource versions for the operation. The default HDAP settings are equivalent to:

Accept-API-Version: protocol=2.1,resource=1.0

X-ForgeRock-TransactionId

The optional X-ForgeRock-TransactionId header helps to track related requests through the Ping Identity Platform.

X-ForgeRock-TransactionId: transactionID

The transactionID consists of a unique identifier for the transaction optionally followed by a sequence number for the individual request.

You configure platform products to trust transaction IDs and let them propagate for audit purposes. For DS, refer to Log LDAP access to files or Log HTTP access to files.

Query parameters

HDAP supports the following query string parameters.

Some parameter values are not safe for URLs.

URL-encode parameter values as necessary.

_action=<action>

Perform an extended action as part of an HTTP POST.

The <action> is one of:

accountUsability
create
modifyPassword
rename
resetPassword
schema

_countOnly=true

Return a count of query results without returning the resources.

This parameter requires protocol version 2.2 or later in the Accept-API-Version request header:

Accept-API-Version: protocol=2.2,resource=1.0

deleteOldRdn=true

Delete the old RDN value when renaming a resource.

dryRun=true

Discover how a server reacts to an operation without performing the operation.

This parameter relies on the LDAP no-op control, OID 1.3.6.1.4.1.4203.1.10.2.

_fields=<field>[,<field>…]

Return only the specified fields in the body of the response.

The <field> values are JSON pointers. In {"parent":{"child":"value"}}, parent/child refers to "child": "value".

When the request omits the _field parameter, HDAP returns fields for all LDAP user attributes.

HDAP returns fields for operational attributes only when specifically requested. Use +, which encodes to %2B, to return fields for all operational attributes.

manageDsaIT=true

Manage referrals.

This parameter relies on the LDAP manage DSAIT request control, OID 2.16.840.1.113730.3.4.2.

objectClasses=<objectClass>[,<objectClass>…]

Return JSON schema for a resource to create based on the LDAP object classes and the parent resource.

_pagedResultsCookie=<cookie>

The <cookie> is an opaque string HDAP uses when paging to keep track of the position in the query results:

Set the _pageSize in the request to a non-zero number.

HDAP returns the cookie with the first request.
Supply the cookie in subsequent requests until HDAP returns a null cookie when it reaches the final page.

_pageSize=<number>

Return query results in pages of this size.

After the initial request, use _pagedResultsCookie or _pageResultsOffset to page through the results.

passwordQualityAdvice=true

Get additional information for a failed password update.

The passwordQualityAdvice parameter relies on the DS LDAP password quality advice control, OID 1.3.6.1.4.1.36733.2.1.5.5.

_prettyPrint=true

Format the body of the response.

_queryFilter=filter-expression

Query resources matching the filter expression.

You must URL-escape the filter-expression.

relax=true

Relax data and service rules temporarily for the requested update.

This parameter relies on the LDAP relax rules control, OID 1.3.6.1.4.1.4203.666.5.12.

scope=<scope>

Scope of the query; one of:

base: Query only the target resource.
one (default): Query direct child resources of the target resource.
sub: Query the target resource and all child resources recursively.
subordinates: Query all child resources recursively but do not include the target resource.

_sortKeys=(|-)[.var]##<field>##[,(|-)<field>…]

Sort the query results based on the specified field(s).

Use + for ascending order (default, encoded as %2B).
Use - for descending order.

subentries=true

Return resources corresponding to LDAP subentries. Subentries aren’t returned by default.

This parameter relies on the LDAP subentries request control, OID 1.3.6.1.4.1.4203.1.10.1.

subtreeDelete=true

Delete an entire subtree of resources.

This parameter relies on the LDAP subtree delete control, OID 1.2.840.113556.1.4.805.

_totalPagedResultsPolicy=<policy>

When a _pageSize is non-zero, HDAP can calculate totalPagedResults. It returns the totalPagedResults in the response depending on the <policy>:

"totalPagedResults": -1 by default, when _pageSize is not set, or when _totalPagedResultsPolicy=NONE.
An estimated count when _totalPagedResultsPolicy=ESTIMATE.
The exact count when _totalPagedResultsPolicy=EXACT, if possible.

Filter expressions

Query filters request entries matching the filter expression. You must URL-escape the filter expression.

The string representation of the filter expression is:

Expr           = OrExpr
OrExpr         = AndExpr ( 'or' AndExpr ) *
AndExpr        = NotExpr ( 'and' NotExpr ) *
NotExpr        = '!' PrimaryExpr | PrimaryExpr
PrimaryExpr    = '(' Expr ')' | ComparisonExpr | PresenceExpr | LiteralExpr
ComparisonExpr = Pointer OpName JsonValue
PresenceExpr   = Pointer 'pr'
LiteralExpr    = 'true' | 'false'
Pointer        = JSON pointer
OpName         = 'eq' |  # equal to
                 'co' |  # contains
                 'sw' |  # starts with
                 'lt' |  # less than
                 'le' |  # less than or equal to
                 'gt' |  # greater than
                 'ge' |  # greater than or equal to
                 STRING  # extended operator
JsonValue      = NUMBER | BOOLEAN | '"' UTF8STRING '"'
STRING         = ASCII string not containing white-space
UTF8STRING     = UTF-8 string possibly containing white-space

JsonValue components of filter expressions follow RFC 7159: The JavaScript Object Notation (JSON) Data Interchange Format. In particular, as described in section 7 of the RFC, the escape character in strings is the backslash character. For example, to match the identifier test\, use _id eq 'test\\'. In the JSON resource, the \ is escaped the same way: "_id":"test\\".

When using a query filter in a URL, the filter expression is part of a query string parameter and requires URL encoding. For details, refer to RFC 3986: Uniform Resource Identifier (URI): Generic Syntax. For example, spaces, double quotes, parentheses, and exclamation characters need URL encoding. The following rules apply to URL query components:

query       = *( pchar / "/" / "?" )
pchar       = unreserved / pct-encoded / sub-delims / ":" / "@"
unreserved  = ALPHA / DIGIT / "-" / "." / "_" / "~"
pct-encoded = "%" HEXDIG HEXDIG
sub-delims  = "!" / "$" / "&" / "'" / "(" / ")"
                  / "*" / "+" / "," / ";" / "="

ALPHA, DIGIT, and HEXDIG are core rules of RFC 5234: Augmented BNF for Syntax Specifications:

ALPHA       =  %x41-5A / %x61-7A   ; A-Z / a-z
DIGIT       =  %x30-39             ; 0-9
HEXDIG      =  DIGIT / "A" / "B" / "C" / "D" / "E" / "F"

A backslash escape character in a JsonValue component is percent-encoded in the URL query string parameter as %5C. To encode the query filter expression uid eq 'test\\', use uid+eq'test%5C%5C'+, for example.

A simple filter expression can represent a comparison, presence, or a literal value.

For comparison expressions use json-pointer comparator json-value, where the comparator is one of the following:

eq (equals)
co (contains)
sw (starts with)
lt (less than)
le (less than or equal to)
gt (greater than)
ge (greater than or equal to)

For presence, use json-pointer pr to match resources where:

The JSON pointer is present.
The value it points to is not null.

Literal values include true (match anything) and false (match nothing).

Complex expressions employ and, or, and ! (not), with parentheses, (expression), to group expressions.
