Mart Portal Display Name shows as Full qualified DN string instead of UserName (4378059)

After upgrade from 12.5 to 14.0. We have noticed the LDAP login user displays name as Full qualified DN string instead of actual User name

eg

This is due to user is already exist in DB so the user display name is not changed

Workaround to remove the existing user from database by running below query:

delete from m9User where IsInternal = 1;

login to Mart Portal use Ldap user again this should update the data in database table and display username correctly
