Hello, I have what is probably a fairly unusual requirement and am wondering if anyone can suggest a possible solution. I am currently migrating a large number of IMAP/POP accounts from one server to another. The old server using a schema of CLIENTID-0, CLIENTID-1 etc as the naming schema, and it is required that the new server use the user@domain naming schema. I am looking for a way to maintain multiple logins for the mailboxes, so that it is not necessary for every client to change their login details. So, for example a user can log in as OLDUSER-1 or user@xxxxxxxxxx and go to the same mailbox. Does anyone have a working configuration for this? I have been working on the problem using saslauthd with Linux PAM. PAM has a mechanism to allow you to change the users username during login, which is used in the pam_ftp module. However, my cursory looks at the code seem to indicate that any changes to this value will not be carried down the path from PAM -> saslauthd -> imapd. -- Malcolm Locke - Systems Administrator, http://www.e2-media.co.nz/ ---- Cyrus Home Page: http://asg.web.cmu.edu/cyrus Cyrus Wiki/FAQ: http://cyruswiki.andrew.cmu.edu List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
