So, ldbsearch revealed:
dn: name=domain admins(a)ad.nwra.com,cn=groups,cn=ad.nwra.com,cn=sysdb
...
ghost: template-admin(a)ad.nwra.com
and:
sss_cache -g 'domain admins(a)ad.nwra.com'
did the trick of clearing that.
As a followup - is it reasonable for sssd to return an empty group in
this situation?
