Comment 1 RHEL Product and Program Management 2012-06-25 09:58:30 EDT
This request was evaluated by Red Hat Product Management for inclusion
in a Red Hat Enterprise Linux release.  Product Management has
requested further review of this request by Red Hat Engineering, for
potential inclusion in a Red Hat Enterprise Linux release for currently
deployed products.  This request is not yet committed for inclusion in
a release.
Comment 2 Alex Wood 2012-08-03 15:50:55 EDT
At the time this bug was filed, the migration script did not offer the ability to migrate to a standalone Candlepin server.  That ability has since been added with the feature of collecting different credentials for both RHN and the standalone server.

That being said, if you provide RHN credentials that are incorrect, you will still see this exception in the log.  Unfortunately, there is not much that we can do about the message that the XMLRPC call is returning.

The best I think we can do is add a log message above the stack trace saying something like, "Communication to RHN failed.  Check password?"  But I feel like the message that gets displayed on the terminal is already pretty explicit about what happened: "Unable to authenticate to RHN Classic."  I'm marking this NEEDINFO until a decision is reached.
Comment 3 Alex Wood 2012-08-17 14:50:55 EDT
The migration script now works against standalone Candlepin instances as of commit 4340a7af08b07a23093ac75880274655f520364c.
