Hi All. I have a some problem with dovecot, when I try to use nss in
auth userdb. nss was setup to resolve users and group by winbind. nss
and winbind works well, command "id user" shows remote user's
info. I
would like to use nss userdb, but dovecot crashes on start. Is this a
bug or incorrect settings? Thank you for any help.
