number of users in a group, but the total length of the membership string.
So the number of users that can be in a group may also depend on the
length of all their usernames.

I have no idea if glibc has changed, but a long time ago it was a fixed
length char array that stored the group membership. This doesn't really
help your issue, but hopefully it provides more information.
