Comment 2 Najmuddin Chirammal 2012-09-27 14:06:03 UTC

The issue is not specific to krb5-server-1.9-33.el6_3.3.x86_64.

steps to re-produce: 

* Disable selinux & reboot the machine  
# rm /var/tmp/DNS_25 (if was created earlier)
* start ipa (or named)
	it creates a DNS_25 with no context
* enable selinux 
* reboot the machine
	since there was no context created for DNS_25, system sets the default tmp_t[1]

* start ipa (or named)
	if selinux is enforcing named wont start

* remove the file DNS_25
start named again.. it'll create the file with correct context.[2]

[1] -rw-------. named  named  system_u:object_r:tmp_t:s0       DNS_25

[2] -rw-------. named  named  unconfined_u:object_r:named_tmp_t:s0 DNS_25

Comment 4 Daniel Walsh 2012-09-28 09:43:15 UTC

bfdad301c406d5d27270ae5d66bc2bb0683b5a6e fixes this problem in Fedora 18.

For RHEL6 you have to add 

/var/tmp/DNS_25                           gen_context(system_u:object_r:named_tmp_t,s0)

Then the relabel should fix it.

In RHEl7 this will be labeled as kerberos content.
