This limit is somewhat historical but cannot easily be changed because  
this max # is hard-coded into the NFS protocol, which needs to  
describe which groups a user belongs to.  If you're not using NFS, you  
might try changing the declaration of KI_NGROUPS in /usr/src/sys/ 
user.h and build a new kernel, I believe....
