    Check the FAQ...

    7.6) How can I have more than 16 groups per user?
    The number of groups per user can be increased to at most 32:

        set ngroups_max = 32

    This setting may give rise to NFS interoperability problems, as typical
    NFS servers only support 16 groups when using AUTH_SYS/AUTH_UNIX.

    The other NFS authentication mechanisms map "netids" to usernames on the
    servers and can support more than 16 groups.
