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.
