RH-SSO REST-API Query Performance Is Slow With Users Originating From LDAP User Federation

Solution Verified - Updated -

Issue

  • When querying users with {{host}}/auth/admin/realms/{{realm}}/users?max=2000000 from RHSSO we have very slow response times in cases the users in the realm are federated from an LDAP storage. It takes up to 5min to get all users. If users only exists in local storage from RHSSO we have the result in less than 1sec
