[Samba] NT_STATUS_INSUFFICIENT_RESOURCES ... why? (fwd)

[John Gehring]

I've included a very small program that I run to cause the 
NT_STATUS_INSUFFICIENT_RESOURCES problem. If you run this against a PDC 
with a small number of groups (<100), you should get the error in well 
under one minute.

#include <stdlib.h>
#include "grp.h"
#include <time.h>
#include <sys/time.h>

int main( int argc, char *argv[] )
{
         int i;
         int iLoopCount = 0;
         group *groupStruct;
         bool keepon = true;

         while( keepon ) {
                 iLoopCount++;
                 i = 0;
                 while( ( groupStruct = getgrent() ) != NULL ) {
                         i++;
                 }
                 time_t the_time;
                 the_time = time( NULL );

                 printf( "[%d]  i is %d:  %s", iLoopCount, i, ctime( 
&the_time) );
                 if( i<51 ) { // 50 is the number of groups in 
/etc/group on the test client.
                         keepon = false;
                 }
                 endgrent();
         }


}
