Reference BugID 1030. Though marked as resolved, "getent group" has never worked
properly for us on Solaris - at least since 2.2.8 - and it is still broken. We
get only the groups from /etc/group and one group from AD (domain admins). We
presume the next group (domain users) is too big or has too many members. We see
this problem under Solaris 8, 9 and 10. We're currently running 3.0.14a (latest)
and configure --with=ldap --with-ldapsam --with-acl-support --with-winbind.
