Description of problem:

When retrieving the external usergroups an error is shown:

[root@wallsat615 ~]# curl -s -u admin:password https://$(hostname)/api/auth_source_ldaps/4/external_usergroups | json_reformat
{
    "error": {
        "message": "Association not found for auth_source_ldap"
    }
}

When querying the auth source itself we can see them:

[root@wallsat615 ~]# curl -s -u admin:password https://$(hostname)/api/auth_source_ldaps/4 | jq -r '.external_usergroups'
[
  {
    "id": 1,
    "name": "grp_satellite"
  }
]

How reproducible:

100%

Is this issue a regression from an earlier version:

Not sure 

Steps to Reproduce:

1. Deploy satellite
2. Setup external ldap auth, + usergroup feature
3. Proceed with the API query

Actual behavior:
Error message for a specific endpoint

Expected behavior:
