I'm in a fairly standard cluster environment: shared storage, bunch of servers each acting as both proxies and backends.
We do /bin/checkpassword authentication, allowing a great deal of flexibility...protection against brute force, billing mechanisms, but relevant to this issue, I have it set up to allow users to login with either their username (if they are in one of our default domains) or their email address.
I'm realizing now that as a consequence of this, "joe" and "joe@xecu.net" are unique as far as dovecot is concerned. Users who login with just their username (and not the full email address) can get assigned to a different backend server than when they login with the full email address (which would also include LMTP deliveries). This has been happening for years, a few broken indexes here and there that seem to resolve themselves, so it hasn't been impacting the service, but I'd like to correct it properly.
Can return Dovecot Extra Fields as describes in: http://wiki2.dovecot.org/AuthDatabase/CheckPassword ? userdb_user should change the username.
Is there a way to manipulate this? For example, if I moved the authentication to the proxy layer (it's currently proxy=y nopassword=y), and set $ENV{USER} to the full email address, will director use that for selection instead of the user-supplied username?
