Cause
- When forest level LDAP authentication is configured, the username of the LDAP user for role mapping should be configured in the format of <username>@<domain> which is exactly the userPincipalName that customer configures for the user in LDAP server.
Résolution
- If Windows Domain Controller is the LDAP server, the userPrincipalName can be retried from user's properties via Active Directory Users and Computers. Please note the Advanced Features in View tab needs to be enabled to show the Attribute Editor of user.
