-- In some cases, the mechListMIC is a sequence of GeneralString,
-- rather than an OCTET STRING. We define that sequence here so
-- that we can call its dissector.
-- The IRC discussion at
--
-- http://irc.vernstok.nl/samba-technical.dy
--
-- seems to suggest that it's a Kerberos principal of some sort, thanks
-- to some flavor of "embrace, extend, expectorate" sequence from
-- Microsoft.
