Couldn't drop privileges: User is missing UID (see mail_uid setting)
- by drecute
I'm hoping I can use some help.
I'm configuring dovecot_ldap, but I can't seem to be able to get dovecot to authenticate the ldap user.
Below is my config and log info:
hosts = 192.168.128.45:3268
dn = cn=Administrator,cn=Users,dc=company,dc=example,dc=com
dnpass = "passwd"
auth_bind = yes
ldap_version = 3
base = dc=company, dc=example, dc=com
user_attrs = sAMAccountName=home=/var/vmail/example.com/%$,uid=1001,gid=1001
user_filter = (&(sAMAccountName=%Ln))
pass_filter = (&(ObjectClass=person)(sAMAccountName=%u))
