Running today's current, the following sequence always panics the machine.

smbutil lookup fileserver
Got response from 203.0.113.77
IP address of fileserver: 203.0.113.77
storm~;smbutil login //mwlucas@fileserver
Password:
smbutil: unable to open connection: syserr = Authentication error
smbutil: could not login to server FILESERVER: syserr = Authentication error
storm~;smbutil login //mwlucas@fileserver
Password:
Connected to MWLUCAS
storm~;smbutil logout //mwlucas@fileserver

"fileserver" is a Win 7 VM, fresh install, no security updates, behind a firewall.

/etc/nsmb.conf is:

[default]
nbns=203.0.113.77
username=mwlucas
workgroup=MWL
password=$$obfuscated

100% reproducible.

This panic looks kind of reminiscent to another one that's popped up at $work recently, which was tied down to a failed KASSERT.

^Triage: I'm sorry that this PR did not get addressed in a timely fashion.

By now, the version that it was created against is long out of support.
Please re-open if it is still a problem on a supported version.
