Why? Create a 'master account'. Just add a pam_allow sufficient prior to the pam_passdb/pam_unix module and you can authenticate as anyone with any password; or create a master password using pam_userlist. At the same time the user's can authenticate with their own passwords. This lets you do simple authentication [saslauthd] for the duration of the migration. If you want create a separate imap service that only listens on 127.0.0.1 to use this 'broken' authentication setup. > My goal is to migrate things over to a newer server running gentoo > linux, the maintained version of cyrus-imapd there is 2.4.12 (the older > 2.2.13 from a separate gentoo-overlay didn't compile for me). > Moving the mysql-DB shouldn't be much of a problem, the web-cyradm tool > runs on gentoo already > So my question is: how to move things in the most stress-free way > Could I simply copy over /var/spool/imap etc, and start the newer version? Possibly, I'd rsync it, give it a try and see what happens. I've moved from 2.3 -> 2.4 but haven't uses 2.2 in ages. > Do I have to somehow convert things? If yes, is it problematic? 2.3 -> 2.4 was pretty simple; worst part was the database upgrades [which took place automatically in-place]. They really grind the drives. > I am thinking about just trying it for a test, but I would really feel > much better with some competent feedback from the cyrus-imap-community.
