I am having an issue that is only present since about April after updating packages.

When I am accessing servers and use 'sudo su' to access root and enter my password, I'll get:

 sudo: PAM account management error: Permission denied \
 sudo: a password is required

However, when I exit and restart the SSH session, it works fine. This a periodic issue and does not happen on all servers at the same time in my environment. I have noticed that the sssd service reports offline sometimes, but is back up and the log timings don't seem to match up with the events. I have turned on base level logging for sssd, but have not seen anything that is inherently apparent as the issue. Any insight would be welcomed.
