>             LOG.debug("SASL server DIGEST-MD5 callback: setting "

>           }

> Looking at identifier implementations, e.g. AbstractDelegationTokenIdentifier (and others),
I can see that getUser method can return null. If debug logging is enabled, this NPEs.
> If getUser is not expected to return NULL, it should either be checked and erred upon
better here, or the error should be allowed to happen where it would otherwise happen, not
in some debug log path.
