And there is also AVC for setgid
SELinux is preventing /usr/libexec/sssd/selinux_child from using the setgid capability.
***** Plugin catchall (100. confidence) suggests **************************
If you believe that selinux_child should have the setgid capability by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep selinux_child /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
