The RHN client tool now creates a file at /var/spool/up2date/loginAuth.pkl containing login caching. "yum clean all" should delete this file since it can become corrupt to force it to be recreated on next run.
Release note added. If any revisions are required, please set the "requires_release_notes" flag to "?" and edit the "Release Notes" field accordingly. All revisions will be proofread by the Engineering Content Services team. New Contents: yum-rhn-plugin creates creates a file at /var/spool/up2date/loginAuth.pkl that caches login information. If the contents of this file were to become corrupt, attempts to log in would result in a 404 error. Now, yum-rhn-plugin deletes this file at the end of each transaction and creates a new copy the next time that yum is run. Renewing this file ensures that cached login information is current and uncorrupted.
