OCS 2.2RC1 LDAP MemberOf attrubute

Hi, I had successfully configured LDAP authentication for 2.2 RC2. LDAP authenticates users but it seems to ommit the memberof attribute in config. To be able to enable ldap login i had to apply a little patch:

modify backend/identity/methode/ldap.php lines :

$f1_value=$_SESSION['OCS']['details'][$f1_name];
$f2_value=$_SESSION['OCS']['details'][$f2_name];
to:
$f1_value=$config['LDAP_CHECK_FIELD1_VALUE'];
$f2_value=$config['LDAP_CHECK_FIELD2_VALUE'];

With above all AD users are able to login but all of them are given sadmin role. Looks like memberOf attribute is not checked.

My LDAP config is:

CONEX_LDAP_SERVEUR:IP of domain controller (MS AD 2008r2)

CONEX_ROOT_DN: DN of user who is used to query AD

CONEX_ROOT_PW: pass for above

CONEX_LDAP_PORT: 389

CONEX_DN_BASE_LDAP: OU=it,OU=OurUsers,DC=domain,DC=name

CONEX_LOGIN_FIELD: SAMAccountName

CONEX_LDAP_PROTOCOL_VERSION: 3

CONEX_LDAP_CHECK_FIELD1_NAME: memberOf

CONEX_LDAP_CHECK_FIELD1_VALUE: CN=grp.ocs.admin,OU=OurGroups,DC=domain,DC=name

CONEX_LDAP_CHECK_FIELD1_ROLE: Super Administrators

FIELD 2 and rest are unconfigured.

Above config works perfectly on version 2.1.2 of OCS server. 

EDIT:

I think I have found a possible bug in ldap:

when I have uncommented debug in in /usr/share/ocsinventory-reports/ocsreports/backend/identity/methode/ldap.php it appeared:

field1: memberOf value=CN=grp.ocs.admin,OU=OurGroups,DC=domain,DC=name condition: CN=grp.ocs.admin,OU=OurGroups,DC=domain,DC=name role=sadmin level=
field2: value= condition: role=admin level=
user: jan.kos will have level= and role=sadmin

Above user doesn't belong to ldap group: grp.ocs.admin. Seems to me, that

condition is copied to value somewhere. Am I right?
