We're having some trouble with sssd on centos 7 under load on a VPS.
389ds ldap server for id/auth. Part may be an issue with the VPS, but
I'm trying to track down all possible issues.
Also, we realized that we were running in a bit of a bad state - the
primary ldap server was not available, but the backup was.
Some logs:
General question, is this bad?:

don't know why it wasn't able to reconnect to the backup, or perhaps it
did, but just not logged.
