[Dovecot] plain text auth

[ohp at pyrenet.fr]

Hi everyone,

This is my second try with dovecot, and still no luck.
What I want is twig to work with dovecot on the localhost address .

I need to authenticate through pam for real accounts and through pgsql for
virtual ones.

I just cant autenticate:
logs are : imap-:login: Authenticate PLAIN failed: Unsupported
authentication  mechanism
or: Aborted login: method = PLAIN

Could someone please share a working config file that does what I want?
I'm struggling for weeks now both on tyhe alpha5 and beta1 versions.

TIA
