Creating OAuth2 Provider in AM 5.5.x and 6.x fails with a Could not initialise script configurations for realm error when using ssoadm

Symptoms

A blank response is shown when using a command such as the following to create the OAuth2 Provider:

$ ./ssoadm add-svc-realm -s OAuth2Provider -e / -u amadmin -f pwd.txt -D oauth2providerconfig.txt

Where the oauth2providerconfig.txt file contains the forgerock-oauth2-provider-oidc-claims-extension-script attribute. 

The AM console does not show the creation of the OAuth2Provider.

Debug log

You will see the following error in the ssoadm Configuration debug log when this happens:

Recent Changes

Upgraded to, or installed AM 5.5 or later.

Causes

The introduction of authentication tree nodes in AM 5.5 has caused an issue with modifying the script configuration in the OAuth2 provider service. The presence of the forgerock-oauth2-provider-oidc-claims-extension-script attribute prevents the OAuth2 provider being created or the custom script being updated for existing providers.

Solution

This issue can be resolved using one of the following approaches:

• Use Amster to create the OAuth2 provider
• Use the REST API to create the OAuth2 provider
• Exclude the problematic attribute and create the OAuth2 provider using ssoadm

Use Amster to create the OAuth2 provider

Create the OAuth provider as described in: Entity Reference › OAuth2Provider › create.

Use the REST API to create the OAuth2 provider

You can create the OAuth2 provider using the /realm-config/services/oauth-oidc REST endpoint​. You can use the API Explorer to try out this endpoint as detailed in Development Guide › Introducing the API Explorer, which will provide the OAuth2 provider data you should include in the REST call or you can query the OAuth2 provider service first as demonstrated in the following example:

1. Authenticate as an admin user. For example:

   $ curl -X POST -H "X-OpenAM-Username: amadmin" -H "X-OpenAM-Password: cangetinam" -H "Content-Type: application/json" -H "Accept-API-Version: resource=2.1"  http://host1.example.com:8080/openam/json/realms/root/authenticate
   

   Example response:

   { "tokenId": "AQIC5wM2LY4SfcxsuvGEjcsppDSFR8H8DYBSouTtz3m64PI.*AAJTSQACMDIAAlNLABQtNTQwMTU3NzgxODI0NzE3OTIwNAEwNDU2NjE0*", "successUrl": "/openam/console", "realm": "/" }

2. Retrieve the OAuth2Provider service details using the following curl command:

   $ curl -X GET -H "iPlanetDirectoryPro: AQIC5wM2LY4Sfcxs...EwNDU2NjE0*" -H "Content-Type: application/json" http://host1.example.com:8080/openam/json/realms/root/realm-config/services/oauth-oidc 
   

   Example response (this has been truncated due to the size of response):

   {
       "_id": "",
       "_rev": "-2046488110",
       "coreOAuth2Config": {
           "refreshTokenLifetime": 604800,
   ...
   ...
     "_type": {
       "_id": "oauth-oidc",
       "name": "OAuth2 Provider",
       "collection": false
     }
   }
   

3. Create the OAuth2 provider using the following curl command; the data option should include the response from step 2 with the configuration updated for the new provider, and the first _id and _rev fields removed, for example:

   $ curl -X PUT -H "iPlanetDirectoryPro: AQIC5wM2LY4Sfcxs...EwNDU2NjE0*" -H "Content-Type: application/json" -H "Accept-API-Version: resource=1.0" -d '{
       "coreOAuth2Config": {
           "refreshTokenLifetime": 604800,
   ...
   ...
     "_type": {
       "_id": "oauth-oidc",
       "name": "OAuth2 Provider",
       "collection": false
     }
   }' http://host1.example.com:8080/openam/json/realms/root/realm-config/services/oauth-oidc
   

   Example response (this has been truncated due to the size of response):

   {
       "_id": "",
       "_rev": "-870213730",
       "coreOAuth2Config": {
           "refreshTokenLifetime": 604800,
   .........
       "_type": {
           "_id": "oauth-oidc",
           "name": "OAuth2 Provider",
           "collection": false
       }
   }

Exclude the problematic attribute and create the OAuth2 provider using ssoadm

1. Remove the following attribute from your OAuth2 provider configuration file:

   forgerock-oauth2-provider-oidc-claims-extension-script

2. Re-run the ssoadm command to create the OAuth2 provider, for example:

   $ ./ssoadm add-svc-realm -s OAuth2Provider -e / -u amadmin -f pwd.txt -D oauth2providerconfig.txt

3. Add the custom claims script in the AM console by navigating to: Realms > [Realm Name] > Services > OAuth2 Provider > OpenID Connect > OIDC Claims Script and adding your custom claims script.
