[Dovecot] Is it possible to authenticate against Active Direcotry using the whole e-mail?

[Δημήτριος Καραπιπέ]

Hi all!

Is it possible to authenticate against Active Directory, using the whole 
e-mail address and not
the user part (%n), so that if you support mutiple domains, all users 
should authenticate with their e-mail addresses.

I use
auth_bind_userdn = DOMAIN \ %u
but somehow the *mail* attribute of Active/LDAP should be employed.


thanks in advance
