I'm setting up a mail system using Postfix (OpenLDAP backend) and Cyrus-IMAP on Debian.

Goal: I'd love to go ahead with GSSAPI authentication. I've tested the whole setup on virtual machines on my laptop, and everything works.

Problem: I need mail server(s) running sooner than I have time to migrate a few hundreds of Windows machines. That means, the Windows users will have to use separate username/passwords for their e-mail accounts only. Which is ugly. Which I'd like to avoid.

Ideally, I'd need a behavior of GSSAPI-enabled sshd. If there's a valid ticket, it just lets you in, if there's none, it asks for a password. Is it possible to do a similar trick with Cyrus-IMAP? Or am I trying to both eat the cookie and to have it?

Can you use a REALM Trust and configure your DNS to have suitable REALM mappings?

There's nothing to map, that's the whole point. There is no AD in place, everything has been managed on computer-by-computer basis (don't ask why). The AD is considered 'too expensive', so I have to figure out some el cheapo solution based on Kerberos/GSSAPI/OpenLDAP/Samba stack, and the Samba part is missing at the moment... – badbishop Feb 3 '12 at 10:19
