Title   : OVER32: Handle up to 1000 Security Equivalences
Keywords: GROUPS TRUSTEES SECURITY EQUIVALENCE RIGHTS SUPERVISOR UTILITY

NetWare can handle a maximum of 32 security equivalences.  To allow
proper indirect trustee assignments, users should not be member of more
than 32 groups.  The preferred solution is to rethink the server's
security structure.  If >32 groups are definitely needed, you can use
OVER32.EXE - it handles up to 1000 security equivalences.  Public Domain
