I've tried this, but it doesn't seem to work.  I've set in
/etc/dovecot/dovecot-ldap.conf:
pass_attrs = mail=user
user_attrs = mail=user

and in dovecot.conf
mail_location = maildir:/mirror/mail/%d/%Ln:INDEX=/var/spool/indexes/%u

and when I login as the user I get a user folder created at:
/mirror/mail/user

It's like the user part is getting cut off at the '@' and then the domain
part is just being dropped, rather than passed back for use in the
mail_location.

Any other ideas?
