Description Ken Fallon 2016-03-08 12:25:47 UTC
Description of problem:
SELinux is preventing kdm from 'create' accesses on the file .dmrc.

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

If you believe that kdm should be allowed create access on the .dmrc 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:
# grep kdm /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Lukas Vrabec 2016-03-09 15:17:25 UTC
Hi, 
Do you know where is file ".dmrc" stored? 

Could you try
# restorecon -v /path/to/.dmrc

Thank you.

Comment 2 Ken Fallon 2016-03-12 09:56:37 UTC
restorecon -Rv /home

Worked. Thanks - closing
