When FreeIPA is installed from a user-data script during cloud-init, some AVCs are encountered. I see the following in Permissive mode on F20 (though I've also seen similar on RHEL 7): --------------------------------------------------- type=USER_AVC msg=audit(1412363312.293:160): pid=293 uid=81 auid=4294967295 ses=4294967295 subj=system_u:system_r:system_dbusd_t:s0-s0:c0.c1023 msg='avc: denied { send_msg } for msgtype=method_return dest=:1.12 spid=10092 tpid=10104 scontext=system_u:system_r:certmonger_t:s0 tcontext=system_u:system_r:cloud_init_t:s0 tclass=dbus exe=2F7573722F62696E2F646275732D6461656D6F6E202864656C6574656429 sauid=81 hostname=? addr=? terminal=?' type=AVC msg=audit(1412363495.207:196): avc: denied { read } for pid=11220 comm="httpd" scontext=system_u:system_r:httpd_t:s0 tcontext=system_u:system_r:cloud_init_t:s0 tclass=key type=AVC msg=audit(1412363495.258:197): avc: denied { write } for pid=11220 comm="httpd" scontext=system_u:system_r:httpd_t:s0 tcontext=system_u:system_r:cloud_init_t:s0 tclass=key type=AVC msg=audit(1412363513.757:209): avc: denied { write } for pid=11367 comm="setfiles" path="/var/log/vm-post-cloud-init-ipa.sh.log" dev="vda1" ino=3252 scontext=system_u:system_r:setfiles_t:s0 tcontext=system_u:object_r:cloud_log_t:s0 tclass=file type=AVC msg=audit(1412363928.436:220): avc: denied { read } for pid=11390 comm="httpd" scontext=system_u:system_r:httpd_t:s0 tcontext=system_u:system_r:cloud_init_t:s0 tclass=key [ipauser@ipa ~]$ sudo audit2allow -a #============= certmonger_t ============== allow certmonger_t cloud_init_t:dbus send_msg; #============= httpd_t ============== allow httpd_t cloud_init_t:key { read write }; #============= setfiles_t ============== allow setfiles_t cloud_log_t:file write; ---------------------------------------------------
