True. GPO rules enforced by SSSD are related to login only.

Your are lucky if you didn't work on a project where the customer have 
rules, like having their login enforcement be done by Active Directory 

Anecdote: I worked a few decades ago developing a big Smalltalk 
application for a bank, successfully deployed to OS/2. Many years later 
when they required to migrate from OS/2 they migrated it to Windows and 
started a project to evaluate a migration to Linux in order to choose 
their next platform. We did the entire migration to Linux, the project 
was canned after showing a fully working application (with some small UI 
issues to be fixed if migration was chosen) because their company policy 
said they needed a <insert brand> antivirus on Linux and it wasn't ready 
available. The moral of the history, there are many ways to do the same 
thing on a server, but company policies out of your control can tell you 
not do it that way.

Not true about the samba version;

# wbinfo -t
checking the trust secret for domain MYDOMAIN via RPC calls succeeded
# rpm -qa samba

Running SSSD with AD integration. Again, DISCLAIMER, not the recommended 
samba list configuration, but it works.
