Account Suffix Behaving wierdly

[AlroneRhyn]

Hi ! I was using an old Active Directory plugin and using yours after the upgrade of my wordpress. My users are registered with there 'cn' as login username.

I got a wierd issue :

• If i set Account suffix to @blabla.com: my already existing users can still login as "user" or as "[email protected]". My freelance user ([email protected]) can not log in with either "freelance" nor "[email protected]"
• If i do not set Account suffix: my already existing users can not log anymore with "user" and an error appears with "[email protected]": Simple LDAP Login Error: LDAP credentials are correct and user creation is allowed but an error occurred creating the user in WordPress. Actual error: Sorry this email address is already used (translated). If the user does not exist, it will be created with its mail adresse as login username. My freelance user can not log with "freelance" but can with "[email protected]".

Is it normal that the Account Suffix get this influence over the login process ?

Thank you very much !
