Description Adam Williamson 2017-08-15 05:30:07 UTC
Description of problem:
Happened in normal system use after the 'map' permission was introduced.
SELinux is preventing gdm-session-wor from 'map' accesses on the file /var/lib/sss/mc/passwd.

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

If you believe that gdm-session-wor 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.
allow this access for now by executing:
# ausearch -c 'gdm-session-wor' --raw | audit2allow -M my-gdmsessionwor
# semodule -X 300 -i my-gdmsessionwor.pp
