Description Joachim Frieben 2017-08-12 21:00:39 UTC
Description of problem:
SELinux is preventing gdm from 'map' accesses on the file /var/lib/sss/mc/passwd.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that gdm should be allowed map access on the passwd file 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:
# ausearch -c 'gdm' --raw | audit2allow -M my-gdm
# semodule -X 300 -i my-gdm.pp
