Problems with SELinux and cronjobs

[Gijs]

Hello List,

I'm trying to get my cronjobs to work but after reading all kinds of 
info on SELinux, I'm not even one step closer to solving the problem. I 
have the following in my cronlog (yes, SELinux is set in permissive 
mode, for now..):
May 28 09:15:01 mail crond[21390]: CRON (*system*) ERROR:Could not set 
exec context to user_u:system_r:unconfined_t for user,  but SELinux in 
permissive mode, continuing
May 28 09:15:01 mail crond[21391]: (root) CMD (/somescript.sh)
May 28 09:16:01 mail crond[21395]: CRON (root) ERROR:Could not set exec 
context to root:system_r:unconfined_t:SystemLow-SystemHigh for user,  
but SELinux in permissive mode, continuing
May 28 09:16:01 mail crond[21396]: (root) CMD (/usr/bin/php 
/somephpfile.php > /dev/null 2>&1)

Since the cronjobs run every 15 minutes, I get tons of these messages. 
The first errormessage is from my systemwide cron, and the other is from 
a cronjob that is set with "crontab -e".

[root at mail ~]# ls -laZ /somescript.sh
-rwxr-xr-x  root root root:object_r:user_home_t:s0     /somescript.sh

[root at mail ~]# ls -laZ /somephpfile.php
-rwxr-xr-x  someuser somegroup root:object_r:user_home_t:s0     
/somephpfile.php

I have absolutely no idea what to do to solve this. I have no idea what 
a "exec context" is for that matter, nor can I find any understandable 
information on that subject.

Hope someone can help me with this.

Regards, Gijs
