You first query PAM then LDAP. If your users are in passwd still, you get
a failed password response.
userdb passwd {
}
You read the user data from passwd? I think you've migrated to LDAP?
user = root
user = root
socket listen {
client {
path = /var/spool/postfix/private/auth
mode = 0660
user = postfix
group = postfix
}
}
}
dict {
}
plugin {
}
/etc/dovecot-ldap.conf
hosts = 127.0.0.1:389
sasl_bind = no
auth_bind = yes
auth_bind = no
ldap_version = 3
deref = never
dn = cn=sogo,dc=ameliaschools,dc=com
dnpass=password
base = dc=ameliaschools,dc=com
scope = subtree
pass_attrs = uid=user, userPassword=password
pass_filter = (uid=%u)
Is it possible to have 2 auth methods? Meaning if user and passwd does not
match in pam then go with ldap?

as far as I know, if PAM returns no such user, the next passdb is tried.
If PAM returns password mismatch, it chains to next passdb.
BTW: Dovecot also caches passwords, maybe you are hit by it?
