> When JniBasedUnixGroupsNetgroupMapping or JniBasedUnixGroupsMapping is used, we get segmentation
fault very often. The same system ran 2.2 for months without any problem, but as soon as upgrading
to 2.3, it started crashing.  This resulted in multiple name node crashes per day.
> The server was running nslcd (nss-pam-ldapd-0.7.5-15.el6_3.2). We did not see this problem
on the servers running sssd. 
> There was one change in the C code and it modified the return code handling after getgrouplist()
call. If the function returns 0 or a negative value less than -1, it will do realloc() instead
of returning failure.
