I am using Active directory authentication via gssapi for most users. In
dovecot.conf I have:
auth_mechanisms = plain login gssapi
auth_use_winbind = yes
I also have
passdb { driver = shadow }
userdb { driver = passwd }
for those few users who are NOT AD users.
Even though the AD users do not exist in /etc/passwd or /etc/shadow, Dovecot
ALWAYS first looks
them up in shadow, which ALWAYS fails.
The https://wiki2.dovecot.org/PasswordDatabase wiki says, "these databases
can't be used with
non-plaintext authentication mechanisms."
Is there a way to bypass checking passdb (and userdb?) for these mechanism?
