> There's a limit on the number of "active" groups you can be in at a time, typically 16. Groups were used for permissions for directories on network storage and our version control system at the time.
This is a limitation of NFS, or more specifically AUTH_SYS per RFC 5531 (§A):
A lot (most?) NFS appliances tend to have a setting where you can tell them to ignore the group list that comes in on the RPC call and just do a look-up on the UID themselves: this way they get the full list via LDAP/NIS/AD/whatever and then do permission checks from that.
