PingGateway 2024.6


Extracts credentials from AM and replays them to a login page or to the next filter or handler in the chain. The PasswordReplayFilter does not retry failed authentication attempts.

The PasswordReplayFilter filter uses the AM Post Authentication Plugin com.sun.identity.authentication.spi.JwtReplayPassword. The plugin is triggered for AM authentication chains but not currently for AM authentication trees.

Don’t use the PasswordReplayFilter with AM authentication trees.


  "name": string,
  "type": "PasswordReplayFilter",
  "config": {
    "request": object,
    "loginPage": runtime expression<boolean>,
    "loginPageContentMarker": pattern,
    "credentials": Filter reference,
    "loginPageExtractions": [ object, ... ]


"request": <object>, required

The HTTP request message that replays the credentials.

  "request": object,
    "method": config expression<string>,
    "uri": runtime expression<string>,
    "version": configuration expression<string>,
    "entity": runtime expression<string>,
    "headers": map,
    "form": map

For information about the properties of `request`refer to Request.

The JSON object of request is the config content of a StaticRequestFilter.

"loginPage": runtime expression<boolean>, required unless loginPageContentMarker is defined

true: Direct the request to a login page, extract credentials, and replay them.

false: Pass the request unchanged to the next filter or handler in the chain.

The following example expression resolves to true when the request is an HTTP GET, and the request URI path is /login:

${find(request.uri.path, '/login') and (request.method == 'GET')}
"loginPageContentMarker": pattern, required unless loginPage is defined

A pattern that matches when a response entity is a login page.

For an example route that uses this property, refer to Login form with password replay and cookie filters.

See also Patterns.

"credentials": Filter reference, optional

Filter that injects credentials, making them available for replay. Consider using a FileAttributesFilter or an SqlAttributesFilter.

When this is not specified, credentials must be made available to the request by other means.

See also Filters.

"loginPageExtractions": array of <objects>, optional

Objects to extract values from the login page entity.

  "loginPageExtractions": [
      "name": string,
      "pattern": pattern

For an example route that uses this property, refer to Login which requires a hidden value from the login page.

The extract configuration array is a series of configuration objects. To extract multiple values, use multiple extract configuration objects. Each object has the following fields:

"name": string, required

Name of the field where the extracted value is put.

The names are mapped into attributes.extracted.

For example, if the name is nonce, the value can be obtained with the expression ${attributes.extracted.nonce}.

The name isLoginPage is reserved to hold a boolean that indicates whether the response entity is a login page.

"pattern": pattern, required

The regular expression pattern to find in the entity.

The pattern must contain one capturing group. (If it contains more than one, only the value matching the first group is placed into attributes.extracted.)

For example, suppose the login page entity contains a nonce required to authenticate, and the nonce in the page looks like nonce='n-0S6_WzA2Mj'. To extract n-0S6_WzA2Mj, set "pattern": " nonce='(.*)'".


The following example authenticates requests using static credentials when the request URI path is /login. This PasswordReplayFilter example does not include any mechanism for remembering when authentication has already been successful, it simply replays the authentication every time that the request URI path is /login:

  "handler": {
    "type": "Chain",
    "config": {
      "filters": [{
        "type": "PasswordReplayFilter",
        "config": {
          "loginPage": "${request.uri.path == '/login'}",
          "request": {
            "method": "POST",
            "uri": "",
            "form": {
              "username": [
              "password": [
      "handler": "ReverseProxyHandler"

For additional examples, refer to Configuration templates, and the Javadoc for the PasswordReplayFilter class.
