Description of problem:
Happens during login in the web interface of cobbler
SELinux is preventing /usr/sbin/httpd from 'add_name' accesses on the directory sessionid875a124c4e682ef500ec0f756ab367c4.

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

If you believe that httpd should be allowed add_name access on the sessionid875a124c4e682ef500ec0f756ab367c4 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 /usr/sbin/httpd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
