Problem with SELinux and NIS



Hi,

My test system runs FC4 updated to the latest rpm's as of today. I'm 
trying to get SELinux working and am having a slight problem

I've gotten nfs, samba and ntpd working OK, but I have a problem with NIS 
running yppasswd to set passwords.

With SELinux disabled it work's, with SELinux enabled, in enforcing mode 
and targetted policy it doesn't.

The errors I get are as follows:

/var/log/messages ( edited )

beta rpc.yppasswdd[1778]: update testacc1 (uid=9001) from host 
10.220.1.151 failed
beta rpc.yppasswdd[1778]: password file locked
                                        ^^^^^^^^^^^^^^^^^^^^

/var/log/audit/audit.log

type=AVC msg=audit(1120732794.982:341722): avc:  denied  { write } for

scontext=system_u:system_r:rpcd_t tcontext=system_u:object_r:shadow_t 
tclass=file

So it seems that SELinux is denying rpc.yppasswdd writing 
to /etc/.pwd.lock

How do I allow it to write to that file.

Thank's in advance

Tony
