2- Issue with an unresolvable user in the LDAP.
3-This is intended, i.e: customer needs to have duplicate users in the environment.

Run a search for the specific User ID across all identity sources:
1.Go to the Security Console> Identity tab > Users > Manage existing
2.Under Search Criteria, click on Search for users across all identity sources, enter User ID and run the search.
3.If you get multiple results for the same user, delete all of them except for the required user entry.
