Hello,

I have successfully used dovecot 1.0 Beta 9 to do SASL authentication for postfix using the unix passwd/shadow files.

I need to authenticate with a windows 2003 server using active directory. My system does not support PAM (I'm using slackware) so I cannot take that route. I do not need to use dovecot for POP or IMAP at the present time and so I would like to avoid modifying my active directory schema.

Dovecot seems to be communicating with the active directory server, however it is sending an authentication failure to postfix:

postfix/smtpd[24540]: warning: unknown[XXX.XXX.XXX.X]: SASL LOGIN authentication failed: UxxvcmxxQ6

I don't see any messages in the log from dovecot.

Here is my dovecot-ldap.conf:

hosts = 192.168.1.2:389

dn = "cn=dovecot,cn=Users,dc=DOM,dc=local"
dnpass = "password"
auth_bind = yes

ldap_version = 3

base = cn=Users,dc=DOM,dc=local

deref = never

scope = subtree

default_pass_scheme = CRYPT

user_global_uid = 900

user_global_gid = 900

Can someone point out what I am missing? I can't find documentation on this type of setup.

Thanks in advance.
