On Debian Lenny:
chris at kolab-lenny:~$ touch something
chris at kolab-lenny:~$ chmod 444 something 
chris at kolab-lenny:~$ chown kolab something 
chown: Ändern des Eigentümers von „something“: Die Operation ist nicht erlaubt
chris at kolab-lenny:~$ ls -l something 
-r--r--r-- 1 chris chris 0 17. Jun 15:23 something

Same on Fedora:
[chris at laptop ~]$ touch something
[chris at laptop ~]$ chmod 444 something 
[chris at laptop ~]$ chown apache something 
chown: Ändern des Eigentümers von „something“: Die Operation ist nicht erlaubt
[chris at laptop ~]$ ls -l something 
-r--r--r--. 1 chris chris 0 17. Jun 13:13 something

Only root has CAP_CHOWN, not normal users.

Regards,
Christoph
