Hi,
Attached is a patch for a new option called "appenddomain". This patch works
differently than the virtdomain option in the configuration, so it's not
replicating existing behavior. If there's a better idea on how to do
something like this, please let me know. Explanation follows.
It seems the virtdomain option exists simply to allow users with older
installations of cyrus (non virtual domain) to be able to use their spools
without modifications. The "virtdomain" specified allows users to log in
without a domain, and will auth them properly and use a deprecated path for
the username. The problem with this is that when a user logs in WITH the
domain, the system doesn't strip the domain from the mailbox path
consistently. Further, for new installations, it maintains the old
deprecated non-virtual paths.
What we were looking for was something that would allow users to log in
without a domain, however keep the path for the mailboxes organized against
the hashing rules for virtual domains. So we created an option called
"appenddomain" which, instead of stripping the domain from mailbox paths
and/or logins when the user connects, appends the specified domain to
unqualified usernames. Simply put it converts and qualifies unqualified
usernames when specified.
The patch was generated against Simon Matter's very cool RPM's which we used
because we're on a 64 bit architecture. It was written by Andre Henry, and
seems to compile cleanly and work.
Comments, suggestions? Hope this gets included, thanks.
