Hi Achim

First of all thankx for your input.

The way you set it up was the way I did it. But when I go thru your ldap configuration it doesn't really solves my Problem or, maybe more likely, I don't understand it.

For Auth I want my users to connect to dovecot with user/Password token. In your config I can't see where you match the Password to the AD Password.

For authetification dovecot uses what is configured in passdb in the corresponding ldap config you can see it uses auth_bind=yes and auth_bind_userdn defines the dn used to auth against samb4 ldap. As said on my side cn is identical with sAMAccountName, if it's not on your side you may have to use cn/Password instead of sAMAccountName/Password .

Maybe I wasn't specific enough, what I want to do. Or I don't understand where I you match again the user Password. And again there is a good Chance that the Problem is myself. Weinend

Thankx again.

Hi list Does anyone has experience in setting up dovecot or any other mail system with user auth against a Samba4 AD ? If yes could I get some advice on that Topic or even a link to a ressource where I can get some Information. Googled a lot but didn't find something yet. Thankx in advance.
I did it with dovecot/postfix on debian wheezy, there is alot more info
if you look for dovecot setup agains Microsoft AD.


First create an user for ldap queries:

  >samta-tool user add ldap [password]

Configure dovecot passdb against Samba4 AD, add or change this in your
dovecot.conf bzw. auth-ldap-conf.ext (on wheezy)

# Authentication for LDAP users

passdb {
    driver = ldap
    args = /etc/dovecot/dovecot-ldap-passdb.conf.ext
}

Create /etc/dovecot/dovecot-ldap-passdb.conf.ext, can be you have to use
sAMAccountName instead of cn for auth_bind_userdn and pass_filter. On my
side these are identical because i migrated from samba3/openldap. Filter
is looking for person classes with matchin cn and an exiting mail attribute.

hosts = localhost
auth_bind = yes
auth_bind_userdn = cn=%u,cn=Users,dc=yourdomain,dc=local
ldap_version = 3

base = cn=Users,dc=yourdomain,dc=local
pass_filter = (&(objectClass=person)(cn=%u)(mail=*))
