Please make sure that your Active Directory server has Subsystem for
UNIX-based Applications (SUA) installed on it. This is necessary for
support of POSIX clients like SSSD.

On Active Directory 2008 with SUA installed, you should not need to set
any of the ldap_user_* options in sssd.conf, as Active Directory's POSIX
compatibility layer should be providing the standard values.

If possible, could you also send the complete LDIF (sanitized as needed)
for one example entry in your Active Directory server, so we can see
what attributes it DOES have, and try to work from there?

The ldapsearch command line tool can be used for this.

Thank you very much for the SUA hint. The auth works now :-).

But still ldap_schema = rfc2307bis was not enough information.
I had to adjust:
- ldap_user_name = sAMAccountName
- ldap_user_object_class = person
- ldap_user_uid_number = uSNCreated
- ldap_user_gid_number = logonCount

I want a unique uid (by default it takes the value of the attribute userAccountControll - not unique!). uSNCreated is a unique attribute value in AD. Unforunately sssd auth does not work if ldap_user_gid_number has the same attribute as value as ldap_user_uid_number.. I am still looking for a sensual attribute.
