slapo-memberof across proxy

Hello list,

With this type of setup,

Client (A) <-----> back_ldap Proxy (B) <-----> syncrepl Slave (C) <-----> Master (D)

I have configured the memberof overlay on both (C) and (D). I am able to query both (C) and (D), either to specifically retrieve the memberof attribute or to perform a query which filter is based on the memberof attribute. All works fine with (C) and (D)

If i issue the same type of queries from (A) to (B), i'm able to retrieve the memberof attribute alright *BUT* i cannot perform searches which contain the memberof attribute on the query filter.

Does (B) need any special configuration so that back_ldap can cope with the memberof overlay available on the backend servers?

Thanks in advance,

Hugo Monteiro.
