[Spacewalk-list] Client does not see any packages

[Peter Albrecht]

Hello,

I have installed Spacewalk on CentOS 6.3 and successfully registered a 
client (CentOS 6.3 as well). When I do a "yum repolist" on the client, I 
see the repo from the Spacewalk server but without any packages:

[root at linux52 ~]# yum --verbose repolist
...
Repo-id      : centos63
Repo-name    : CentOS 6.3
Repo-updated : Fri Nov  9 13:23:59 2012
Repo-pkgs    : 0
Repo-size    : 0
Repo-baseurl : http://linux51.site/XMLRPC/GET-REQ/centos63
Repo-expire  : 21.600 second(s) (last: Mon Nov 12 11:48:43 2012)


On the server (linux51.site) I see the following error in 
/var/log/httpd/error_log:

[Mon Nov 12 15:59:35 2012] [error] RHN 3266 2012/11/12 15:59:35 +02:00: 
('Got a GET call, but auth_client declined', '/GET-REQ/centos63/')

Any hints are appreciated.

Thank you,

Peter
