[CentOS] SSSD cache case-sensitivity

Dear all,

I'm running CentOS 7.3 with SSSD. I'm using sssd-ad to talk to an AD 
backend. Group names in the AD contain capitals.

When sssd-ad is working normally, group names returned are all 
lowercase. However, when the AD backend goes offline, group names 
returned from the SSSD cache contain capitals.

The change in case breaks stuff (sshd's AllowGroups, for one).

Has anybody else seen this behavior?
Is there a way to make the group names uniform, whether they come from 
sssd-ad or the cache?
