Can you restart samba itself? If so, you can temporarily insert an override for
the setgroups call which truncates the number of groups down to 16. Something
like:
int setgroups(int ngroups, const gid_t *grouplist) {
_setgroups(ngroups <= 16 ? ngroups : 16, grouplist);
}
If you compile that into a shared object and LD_PRELOAD it things shouldn't
crash. For example, replace the smbd binary with something like:
#! /usr/bin/perl
$ENV{LD_PRELOAD}='/usr/lib/samba/setgroups_truncate.so';
exec {'/usr/sbin/smbd.orig'} 'smbd', @ARGV;
Fixing the paths as appropriate of course…
