Hello Ondrej,
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/htm...
section 2.3.3, discusses SSSD, AD and Sites.
If you have configured DNS sites in AD, then you should be getting back a primary and back DC for your site.
Best,
Frank

Hi List,
I am just trying to run sssd on Ubuntu 14.04 and it seems to be unable to detect the proper AD site it belongs to.
The thing is, that in order to detect the proper site, it needs to connect to some (random) AD controller first.
In our scenario, the box is only allowed to connect to the controller that belongs to the current AD site. Everything else is blocked by the firewall.
So what happens is:
Sssd starts
DNS SRV lookup for the dns domain discovers 15 domain controllers
SSSD tries randomly (couple of them) connect them – one by one
If we are unlucky, none of the first 1-2 controllers found
belongs to the current site
SSSD bails out with timeout, marking the whole AD backend offline
The solution would probably be to connect all of them at once or extend the timeout after each attempt.
What do you think?
Ondrej
