Entourage 2004 – AD Account Lockouts

Hello,

I run a mixed environment with Mac users connecting and bound to our AD. Currently we are running about 50/50 Panther and Tiger builds all of which are behaving without issue. Single sign on is working, password changing is fine, AFP runs flawlessly using ExtremeZ-IP, etc. Our Mac clients use Entourage 2004 (Various versions – 11.3.x to 11.4) for mail and connect over Web DAV to an Exchange 2003 SP2 box. For the most part this too works like a charm.

BUT… recently something has changed. When our Mac users enter their password into Entourage incorrectly it automatically locks out the account. If this were to happen at the system log-in stage they would get the familiar 3 tries before the account is locked out. Same thing if they were authenticating to a separate server. Looking into it further, we see that Entourage is actually sending(hammering) the incorrectly entered password 9x to the Exchange server, which of course promptly locks their account. The store password in keychain option is not enabled. The issue is indiscriminate when it comes to Mac OS or Entourage version.

If anyone has any thoughts on this odd happening PLEASE pass ’em on!

Thanks,

Dave
