Active Directory authentication is case insensitive

Hi…and help!

I am trying to use Active Directory authentication on our V50s (build 6.5.2).

This seems to work, except that users authenticate whatever case they enter they password. (e.g. password, PASSWORD and PaSsWoRd would all be allowed). This is causing problems as the screensaver lock requires users to unlock their device with exactly the same case password as they used to log onto the device with.

AD is case sensitive, so I am confused how passwords with different cases are being allowed. If I try a different password the account is denied access so authentication of some form is happening with the AD.

My WLX.INI contains:

AUTH= glogin
auth [ default=ignore ] /lib/security/pam_setpw.so
auth [ success=2 default=ignore ] /lib/security/pam_guest.so
auth [ success=1 new_authtok_reqd=1 default=ignore ] /lib/security/inifile.so try_first_pass
auth [ success=ok new_authtok_reqd=ok default=die ] /lib/security/pam_smb_auth.so use_first_pass nolocal
auth [ default=ok ] /lib/security/pam_putregistry.so save_ini=/tmp/user.ini
AUTH_SMB.conf=domain=test.com server=191.56.251.138 backupserver=191.56.251.139

Any ideas on what I am doing wrong? Is anyone else successfully using Active Directory authentication and not having this problem?
