Im having a strange problem on my zimbra server. This server hosts 16 domains. One domain randomly does not let the users login.

Orginally this domain was configured for external auth (to an old exchange LDAP) when the problem started.

I then switched them to local authentication and had everyone reset their password. A couple of days later the problem starts again. Whats strange is on occasion one user can login while the other can not. Also the problem comes and goes without me intervening by attempting to restart zimbra.

I have scored the logs as described in the wiki, but i dont know what i am looking for so i could use some help. Of course whenever i try with my test account for that domain it works
