Description Vadim Rutkovsky 2015-05-25 14:42:08 UTC
Description of problem:
SELinux is preventing /usr/sbin/gdm from rmdir access on the directory auth-for-gdm-sVurjk

Version-Release number of selected component (if applicable):
selinux-policy-3.13.1-25.el7.noarch

How reproducible:


Steps to Reproduce:
1. Restart gdm service

Actual results:

SELinux is preventing /usr/sbin/gdm from rmdir access on the directory auth-for-gdm-sVurjk.

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

If you believe that gdm should be allowed rmdir access on the auth-for-gdm-sVurjk directory 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 gdm /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

It seems that some files/directories on your machine are mislabeled. Please run following command:

# restorecon -Rv /var/run/gdm

Comment 3 Vadim Rutkovsky 2015-07-20 10:04:16 UTC
Doesn't happen on clean installation anymore, thanks!
