We're creating the list of gid's on our own, for example
from the info3 struct in the SamLogon reply.

We have a primary gid, and a list of supplementary gids. If
you're saying that for BSD's, the setgroups call overwrites
the effective gid, then the patch Björn sent would be
correct. But I have not seen any reference on this yet, and
the single unix spec does not say anything about setgroups
at all.
