I have been watching this discussion thinking I might learn something, and
today I did. I did some looking for NGROUPS, and I eventually found that the
number of groups allowed can be determined by sysconf(). This implies that it
can be changed by a configuration parameter. Perhaps the program below can
help determine the maximum on the failing system.
/*
* Display the number of groups allowed.
*/
#include <stdio.h>
#include <unistd.h>
int main( int argc, char **argv )
{
long ngroups_max;
ngroups_max = sysconf( _SC_NGROUPS_MAX );
fprintf( stdout, "ngroups_max = %ld\n", ngroups_max );
return 0;
}

just fine.
The number of groups on setgroups() cannot exceed NGROUPS. (And I don't
know where NGROUPS is set.)
