Hello, I use dovecot with a LDAP backend for user account and aliases. The aliases are objects of the class couriermailalias. Some users would like to use the alias address as POP/IMAP login instead of the 'true' account. Is this possible?. I am using dovecot version 1.0,10, from ubuntu hardy packages.

Thanks for any answer, Javier

Hello Javier,

I don't use couriermailalias, but i do use the qmailUser objectclass which provides both mail and mailAlternateAddress attributes. As an example, i would say that you can use something like

user_filter = (&(objectClass=qmailUser)(|(mail=%u)(mailAlternateAddress=%u)))

and

pass_filter = (&(objectClass=qmailUser)((uid=%u)(mailAlternateAddress=%u)))

Hope it helps.

Regards,

Hugo Monteiro.

As Hugo pointed out, if the "alias" is already part of the same LDAP entry the userPassword attribute is located in, you'll have to add some "OR" logic. Otherwise it would involve to read the "key" (aka user account name) from yet another LDAP entry. This is currently not implemented, as far as I know.

Maybe, you could use the external authentification via script http://wiki.dovecot.org/AuthDatabase/CheckPassword, e.g. as last passdb.
