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. -- fct.unl.pt:~# cat .signature Hugo Monteiro Email : hugo.monteiro(a)fct.unl.pt Telefone : +351 212948300 Ext.15307 Web : http://hmonteiro.net Divisão de Informática Faculdade de Ciências e Tecnologia da Universidade Nova de Lisboa Quinta da Torre 2829-516 Caparica Portugal Telefone: +351 212948596 Fax: +351 212948548 www.fct.unl.pt apoio(a)fct.unl.pt fct.unl.pt:~# _
