Public bug reported:

[2794367.925181] apparmor="DENIED" operation="open"
profile="/usr/sbin/unbound" name="/var/lib/sss/mc/initgroups" pid=5111
comm="unbound" requested_mask="r" denied_mask="r" fsuid=0 ouid=0
The unbound AA profile includes abstractions/nameservice which already
has some rules for files under /var/lib/sss/mc. I think that adding
"/var/lib/sss/mc/initgroups r" to abstractions/nameservice would make
sense:
