Ok. That's also my guessing.

I'm not sure to understand how proxyauth works. I google it and find lots
of doc about...proxy imap.
Currently I need to authenticate my user against a LDAP(openldap), so I configure
saslauthd with ldap and works perfectly.
So one of my solution is to have a getpwent (local passwd) with real login
and fake password. And after the migration switch to ldap auth.
Thanks for your help.
