I do not feel very confident using chained links: When I change my configuration to dn: cn=serverBlink,cn=chaining database,cn=plugins,cn=config objectclass: top objectclass: extensibleObject objectclass: nsBackendInstance nsslapd-suffix: ou=region B,ou=people,o=suffix nsfarmserverurl: ldap://serverB:389/ nsmultiplexorbinddn: cn=proxy admin,cn=config nsmultiplexorcredentials: secret cn: serverBlink dn: cn="ou=region B,ou=people,o=suffix",cn=mapping tree,cn=config objectclass: top objectclass: extensibleObject objectclass: nsMappingTree nsslapd-state: backend nsslapd-backend: serverBlink nsslapd-parent-suffix: "ou=people,o=suffix " cn: "ou=region B,ou=people,o=suffix" Server A proxies the correct search to Server B. However, the response is empty if I search for an existing entry of Server B. I also see the search in Server B's access file, but the response is empty. If I contact Server B with the proxy admin credentials, it returns the existing object. This tells me that the ACI's are working. Do you have an explanation for that? Even more disturbing: After I restart Server A, the entire chaining is broken. I get again err=32, but this time server A even does not perform the search twoards Server B. -Reinhard -----Original Message----- From: fedora-directory-users-bounces@xxxxxxxxxx [mailto:fedora-directory-users-bounces@xxxxxxxxxx] On Behalf Of Rich Megginson Sent: Monday, July 20, 2009 2:33 PM To: General discussion list for the 389 Directory server project.

This is good, that Server A actually talks to Server B.

I find the error message not very user-friendly. Anyway, when I use a different bind dn, it says that my sub suffix l=location B,ou=people,o=suffix does not exist.
