to speed up initgroups, make sure you have the netid.byname NIS map. if
you're not familiar with it, the keys should be "unix dot UID at NISDOMAIN",
the values are "UID:GID,GID,GID,...". an example for my account, which
is uid 1232 in domain "ifi":
key: "unix dot 1232 at ifi"
value: "1232:0,6,15,7411,11232"
presto, no iteration through the complete group map needed!
