nobody?

I enabled auth_debug=yes to trace auth problems, in dovecot.log, going from
- service start to
- sogo login and
- mail page activation (only 1 message in in box), then
- service stop:

I see several "cache miss" and "pam authentication failure (password mismatch?)" If I get it right, dovecot tries to auth on PAM, fails, then looks cache, fails, then ask auth to LDAP server

I thought to have
1) only LDAP as auth, not PAM ?
2) enbled user cache...

probably something in my config is wrong, but can't see any complaint by dovecot about the config... ?
I try to follow wiki and other sources, but can't figure it out...

I'm stuck...
