I think we solved this bug recently.
Yes, this is fixed in vdsm 4.18.21.
https://bugzilla.redhat.com/show_bug.cgi?id=1400527
As a workaround, uncheck the "Require authentication" checkbox, but also
fill the user name and password fields with some strings. You don't have
to enter any real values. Using "abcd" or "12345" is OK, the values
will
not be used during the import.

Another bug.
Can you file a bug?
https://bugzilla.redhat.com/enter_bug.cgi?product=vdsm
There's probably no need to open the bug. The error is harmless and we
already have a patch pending for that.
