That sounds like a non-standard extension, and I'd really advise against
relying on it. I won't guarantee that we won't parse for a valid DN and
reject it as an option (it may work right now, but I might call that a
bug rather than a feature).

Ah, yes. That's caused problems for people before as well.

I'm guessing that ActiveDirectory isn't storing the homedir as the
"homeDirectory" attribute by default. You'll have to look up what it
should be in Windows Server 2008 R2, but at least on older systems the
attribute would have been msSFU30HomeDirectory

So you'd set
ldap_user_home_directory = msSFU30HomeDirectory
in the sssd.conf

You shouldn't be. You should only see the list of POSIX-compliant
members. If the user or group members don't have POSIX attributes, we
ignore them, since they aren't (and cannot be) relevant.

Doing an ldap search of a group I get the following for members (without the antiquated methods of mapping msSFU30*)
member: CN=Unix bpm,OU=Service Accounts,OU=Users,OU=Corporate,,DC=Domain,DC=com
member: CN=Ben Kevan,OU=Standard Users,OU=Users,OU=Corporate,,DC=Domain,DC=com
distinguishedName: CN=NorCal Linux Admins,OU=Groups,DC=Domain,DC=com

Is there a way I can see what is being linked by default in sssd? Here's what I had in previous versions of ldap.conf for mapping, maybe that'll help map what they should be in SSSD easier.
