Description of problem:
Happens during login in the web interface of cobbler
SELinux is preventing /usr/sbin/httpd from 'write' accesses on the file /var/lib/cobbler/webui_sessions/sessionid04984e3da611960ba070f58e74ee8a8c.

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

If you believe that httpd should be allowed write access on the sessionid04984e3da611960ba070f58e74ee8a8c 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 /usr/sbin/httpd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
