smart & RedHat Network subscriptions?

[Jim Faulkner]

Hello,

I see that smart supports up2date repositories.  Does smart also support 
RedHat's central repository for RHEL subscribers?  I've tried adding 
https://xmlrpc.rhn.redhat.com/XMLRPC (what up2date connects to on RHEL 
machines) as a channel, however when I try to update the channel I get 
this "Method Not Allowed" error message:

[root at gari ~]# smart update

0%]

Channels have no new packages.

I poked around google and searched the mailing list but I couldn't find 
anyone who had tried this with smart before.  Am I doing something wrong, 
or are subscription-based up2date repositories not supported?

thanks for any help,
