[keycloak-user] Principal name is showing different after switching to KC

Hi, UserPrincipal.getName showing cb3634be-e0e1-479e-aec9-0cb38c8a0468 like this after switching to Keyclock. LDAP uid was showing when we were using LDAP. After syncing users from LDAP to KC, when the application code checks user principal name, it shows this. Any thoughts? Thanks, Valsaraj Viswanathan
