Found the problem.

The Windows user "backup", as which the FreeBSD box authenticates when
mounting the Windows shares, was created on the domain controller
without "Password never expires" enabled, and the business concerned
doesn't have a password recycling policy designed to handle automatic
password expiry of system accounts.

SMBFS expects one of several responses to the authentication phase, but
"your password has expired, please change it" isn't one of them.  I'll
send my findings to Boris, the author of our SMBFS support.

At least this is in the archives, now. :-)

Ciao,
