 - add objectclass groupOfNames to every group (only the groups!)
 - change every occurence of "structuralObjectClass: posixGroup" to "structuralObjectClass: groupOfNames"
-- edit your slapd.conf:
+- add the required (by groupOfNames) member attributes, by using the information from memberUid,
+  eg. memberUid: hugo --> member: uid=hugo,ou=account,o=egw,dc=domain,dc=com
+--> easier: use the provided script
+3. edit your slapd.conf:

-- empty the ldap database (eg. by removing the content of /var/lib/ldap)
-- add the edited ldif file

+-----------
+You can use nis2rfc2307bis.php on newer SuSE distros too, to get groupOfNames and the member
+attributes set, without editing & saving each group in Admin >> Manage groups.

 eGroupWare detects if it can use groupOfNames together with posixGroup and fills the member attribute,
 if you edit the group or changes the members.

+ *  - SuSE's default structural objectClass namedObject get removed from the objectClass(es)
+ *  - member attribute(s) of groupOfNames get set from the posixAccount memberUid and the account-dn
+ *  - memberUid's not found in the whole file get removed!
