this is not a solution because defining service for user in LDAP means
to grant user access to this service not only on a particular server but
on all servers the same user can access too (for example because of some
This is real scenario:
- two servers both running openvpn and ssh services - both configured to
authenticate users against LDAP
- I want user "one" to have access to:
- openvpn service on server1
- ssh service on server2
I'm not able to manage this with sssd even though I try it with comma-
separated list in the ldap_access_order parameter. I don't think this
scenario is so rare in other companies too. This is a quite common
practice in larger companies maintaining dozens of servers and services
to grant users access to specific services on specific servers only (as
we can do easily with pam_ldap).
I will be very surprised if many other companies won't request this
feature being present in sssd if this is a new official way how to
handle LDAP authentication in RHEL 6.

I got a look to at IPA's HBAC and it seems to be overkill to me. I can
imagine such a solution in very large enterprises where kinda more
sophisticated integrated security information management solution might
come in handy.
I think our company(as many others) will stick with "old" pam_ldap
solution which was there working since RHEL4. At least until this
feature is integrated to sssd.
I'm sorry the current means of access control do not work for you.
Unfortunately we have finite time and resources and the next 1.10 release
is already getting quite big. I would suggest raising a feature request
via the usual RHEL channels to bump the priority up.
Or, if you'd be willing to work with us and contribute a patch, I'll be
glad to help with getting you up to speed and getting the patch
