Resolution

The Federation ID needs to be unique.

Log in to Admin Console.
Select Users and edit the affected user profile.
Scroll to Single Sign-On (SSO) and edit the Federation ID with the SSO username so that it is unique. Based on the PBX which is not in use, either one can be deleted, if not federation ID can be removed.

Cause

This issue occurs when the same Federation ID is associated with multiple profiles, which causes a conflict.
