dovecot - Apr 2012 - Modifying LDAP search results for user_attrs

I need to authenticate users via LDAP either by mailaddress or login name.
In both cases the mailbox location is /src/mail/%d/%n. I can easily deduct
that path from the mailaddress, but not so from the login name.

Can I get the mail address as part of fetching user_attrs and modify it on the
fly? Something along the lines of this:

user_attrs = mail:/srv/mail/%d/%n=home,uidNumber=uid,gidNumber=gid

Or would I be able to modify this with a post-login script?

If you have something like mailAddress=user in your pass_attrs and user_attrs,
so that the username gets translated to the mailaddress then you can use %n/%d
in dovecot.conf.

The correct syntax is:

user_attrs = =home=mail:/srv/mail/%d/%n, ..

but this assumes that the login is user at domain.

Without changing the username to mail address you can't use %d/%n directly,
and post-login script would be the only way to go.

Just one note: as far as I know, if your mail directory depends on a 
post-login script, it might be tricky to get LMTP or doveadm commands to 
work properly.
