thanks, reinhard, apparently you are quite right--the development server
on which i performed the initial testing had a much more recent level of
operating system patches than did the deployent system.  in our case, the
sun machines are ldap clients (specifically, of a sun 1 ldap server); it
is from this source that the secondary group information comes.

interestingly, while i was plunking around with this over the weekend i
noticed that by doing a "getent group > /var/tmp/groups_all" followed by
"cp /var/tmp/groups_all /etc/group" (ie, putting all of the unix group
information in the local /etc/group file), suddenly samba could see and
honor 2ndry groups as expected.  admittedly, no substitute for a properly
patched o.s., but perhaps a suitable interim workaround for some other
desperate soul down the road.
