I give some indeed study for eGroupWare + LDAP, compare its use between nis.schema and rfc2307bis.schema, slapcat and diff their result:

modifyTimestamp: 20090220182056ZWe can find that:
- Need to add the new
objectClass: groupOfNamesfor each group. - Need to replace all
structuralObjectClass: posixGroupasstructuralObjectClass: groupOfNames. - Need to add required member attribute, e.g.
member: uid=postmaster,ou=People,dc=example,dc=com. - (HIDDEN RULE!) We need at least ONE member for each group!. eGroupWare web GUI will not allow group without any member, e.g. you can't create group without member, or delete the last member from a group.
So it is time to study how to patch smbldap-tools with rfc2307bis.schema support. May need some backtrace from eGroupWare logic, e.g. how to support both schema and dynamically switch the use of different syntax :D
Some code snippet from eGroupWare (/var/www/egroupware/phpgwapi/inc/class.accounts_ldap.inc.php):
// read the entry first, to check if the dn (account_lid) has changed
$sri = $is_group ? ldap_search($this->ds,$this->group_context,'gidnumber='.abs($data['account_id'])) :
ldap_search($this->ds,$this->user_context,'uidnumber='.$data['account_id']);
$old = ldap_get_entries($this->ds, $sri);
if (!$old['count'])
{
unset($old);
}
else
{
$old = $this->_ldap2array($old[0]);
foreach($old['objectclass'] as $n => $class)
{
$old['objectclass'][$n] = strtolower($class);
} $groupOfNames = in_array('groupofnames',$old ? $old['objectclass'] : $to_write['objectclass']);
if (!$old && $groupOfNames || $members)
{
$to_write = array_merge($to_write,$this->set_members($members,
$data['account_id'],$groupOfNames,$dn));
} function set_members($members,$gid,$groupOfNames=null,$use_cn=null)
{
//echo "<p>accounts_ldap::set_members(".print_r($members,true).",$gid)</p>\n";
if (!($cn = $use_cn) && !($cn = $this->id2name($gid))) return false;
// do that group is a groupOfNames?
if (is_null($groupOfNames)) $groupOfNames = $this->id2name($gid,'groupOfNames');
$to_write = array('memberuid' => array());
foreach((array)$members as $key => $member)
{
if (is_numeric($member)) $member = $this->id2name($member);
if ($member)
{
$to_write['memberuid'][] = $member;
if ($groupOfNames) $to_write['member'][] = 'uid='.$member.','.$this->user_context;
}
}

// hack as groupOfNames requires the member attribute
$to_write['member'][] = 'uid=dummy'.','.$this->user_context;
}
if ($use_cn) return $to_write;
// set the member email addresses as forwards
if ($this->id2name($gid,'account_email') && ($objectclass = $this->id2name($gid,'mailAllowed')))
{

$to_write[$forward] = array();
