Re: push replication with proxy and rwm overlay

Hi again,

Nobody can help me with this?

Can you confirm the rwm overlay can do what I need: remove some values from objectClass attribute?

Thanks.

Hi all,

I'm trying to set up push replication from master to slave through a proxy with rwm overlay. Master, proxy and slave are OpenLDAP 2.4.11 from debian lenny.

On the slave, I don't want samba related attributes so I used the attrs param on syncrepl to only get attributes I want but entries still have sambaSamAccount or sambaGroupMapping as objectClass.

I tried using the rwm overlay to remove these references to samba in objectclass but it did not work and I still get the following error when proxy tries to add the entries on the slave:

error code 0x15: objectClass: value #3 invalid per syntax

Here is the proxy configuration:

include /etc/ldap/schema/core.schema include /etc/ldap/schema/cosine.schema include /etc/ldap/schema/nis.schema include /etc/ldap/schema/inetorgperson.schema include /etc/ldap/schema/samba.schema include /etc/ldap/schema/authldap.schema

pidfile /var/run/slapd/slapd.pid argsfile /var/run/slapd/slapd.args

modulepath /usr/lib/ldap moduleload back_ldap moduleload syncprov moduleload rwm

database ldap suffix "..." rootdn "cn=admin,..." uri ldap://ldap-dmz

I tried upgrading OpenLdap on the proxy to 2.4.17 from backports and also upgraded to squeeze with OpenLdap 2.4.23 but I still get the error.

Am I doing something wrong or is rwm buggy ?

Thanks,
