I'm surprised there isn't more outright swearing on this list! I spent the
whole day on this, sitting down with one working machine side-by-side
the nonworking machine, comparing every setting I could think of, digging
deep into Windows' innards in search of some enemy flag.
Eventually, I came upon this:
https://bugzilla.samba.org/show_bug.cgi?id=7577. The bug report specifies
that systems with Win7 + Microsoft Live Sign-in Assistant don't play nice
with Samba. When I saw the following:
> Looking at a Wireshark dump, it turns out that after the two OIDs we have a
> mechToken [ASN1_CONTEXT(2)] instead of a principal [ASN1_CONTEXT(3)].
... the "Invalid parameter" error suddenly made a lot more sense. I checked
out the list of installed software on the nonworking machine and found that
Windows Live Essentials 2011 had been installed on 11/23. 11/23?!?! Why
was that date so familiar? I logged into BackupPC's web GUI and, yes, 11/23
was the date of the last successful backup of my nonworking machine.
Solving the problem was as easy as uninstalling Windows Live Essentials 2011
and turning off Automatic Updates. I could have tried to apply one of the
patches attached to the bug report, but I prefer to keep to the repositories
whenever possible.
So there you have it. Thread solved.
