selinux on enforcing prevents kerberized accounts from logging in

[Dracula]

Hello

I used  

http://kbase.redhat.com/faq/FAQ_49_6089.shtm 

and 

http://kbase.redhat.com/faq/FAQ_49_6086.shtm 

to set up selinux on our satellite server.  When I set selinux to
enforcing, users cannot log in with their kerberos password to the web
interface on the satellite.  When I set selinux to permissive, users can
log in just fine.  Are there extra incantations I have to add to allow
kerberos logins to the webserver with selinux in enforcing? 

Thanks
