postfix and sasl pwcheck

Hi all,

i am trying to get to work smtp_auth on a debian woody machine. Lots of
problems and i only get errors like 'sasl authentication failed'.

However, other packages like cyrus do work. I tried to trace the postfix
problem as hard as i could, and finally i found out that postfix doesn't
talk with the pwcheck daemon.

Postfix is 1.11.0 for debian, including postfix-tls package and all the
sasl needed libraries/binaries.

Pwcheck has its socket under /var/state/pwcheck/pwcheck, correctly
opened by cyrus/pop and imap servers, but the same socket seems to be
unavailable for postfix. I tried both chrooted and not chrooted, no
change.

Has somebody a idea of how to fix the problem? I didn't find info about
where postfix searches for pwcheck socket, nor about possible permission
problems on the socket that may prevent postfix from using it.

Any help is greatly appreciated, i tried all i could think of.

Thanks a lot.
