Which number of users does it need to make that happen?
Does it make a difference if you increase the size of "grpbuf"
in nss_ldap/files/netbsd.c?
This would only affect the non-_r calls, but eg. getent(1)
uses these, so we could see a difference.
I don't think getgroupmembership() is guilty here, getent(1)
doesn't use it.
