I have a user who is on a PC at the office and checks his mail on occasion from his mac at home. I am a newbie running the mail server on an Xserve running OSX Server 10.4.1. Each time he has checked his mail from Mac Mail at home, he gets an authentication error when he gets to work and tries to access mail from MS Outlook. The error in the log is: Open Directory Error: -14090. I can go into Workgroup Manager and retype the password and then everything is OK.
Any thoughts?
