That says its getting a username, but not matching.

NB, make sure you use VIR_CRED_USERNAME, rather than VIR_CRED_AUTHNAME.
The latter is most never what you want

We explicitly don't include auth credentials in the debug log to
avoid compromising them. So your best option is to attach GDB to
the process.  The qemud/remote.c file, in the remoteDispatchAuthSaslStep
method, you want to peek at the 'args->data.data_val' string.
