Does realm require periodic "rejoining"?

Post by hartzell » 2018/11/15 23:16:39

I've use realm to join an AD domain.

At a previous company, which used Centrify, systems that had been rebooted needed to rejoin the domain. This required manual intervention. It was confusing because apparently credentials (or something) were cached and the system would appear to be working as intended for some period of time (until cached data expired?) before denying logins.

I can't find any information, one way or the other, about if/when a system using realm/sssd might need to rejoin a domain.

I've rebooted my test system and on reboot it's still joined to the domain. That's only slightly comforting though....

Can anyone shed any light on ongoing domain membership?

Thanks!
