I can't find the lines you're talking about. I've got GO 3.7.5. I'd like to create email/imap accounts automatically when users are authenticated in ldap. When I add local user to GO the imap account is created automatically. The problem is when users are authenticated using ldap. I did everything written in http://group-office.com/wiki/Mailserver
My samaccountnames and emial's before '@' are the same, for example my username in AD/ldap is "j.kowalski" my emial is "email@example.com"
If someone would like to help, I can paste my conf's if needed.
