Read the slapo-chain manpage, come back here if you have specific questions.

cheers Paul

Thanks for the links.

After reading man page and the links, I managed to get chain overlay working with simple bind. However, I would like to set using sasl bind since consumer already uses sasl binding to retrieve updates. Is this possible with 2.3.35? Or is there something special to set up for sasl binding to work with chain overlay?

Here is related setting: ==================================================================================== overlay chain chain-rebind-as-user FALSE

chain-uri ldaps://ldap1.example.com chain-rebind-as-user TRUE chain-idassert-bind bindmethod=sasl saslmech=GSSAPI binddn="uid=host/ldap2.example.com,cn=gssapi,cn=auth" mode="self" ====================================================================================

ldap1 is provider and ldap2 is one of consumers.

Here is related log: ==================================================================================== Jun 7 11:30:50 ldap1 slapd[28399]: connection_get(14): got connid=135 Jun 7 11:30:50 ldap1 slapd[28399]: connection_read(14): checking for input on id=135 Jun 7 11:30:50 ldap1 slapd[28399]: do_modify Jun 7 11:30:50 ldap1 slapd[28399]: => get_ctrls Jun 7 11:30:50 ldap1 slapd[28399]: => get_ctrls: oid="2.16.840.1.113730.3.4.18" (critical) Jun 7 11:30:50 ldap1 slapd[28399]: >>> dnNormalize: <uid=user1,ou=people,dc=example,dc=com> Jun 7 11:30:50 ldap1 slapd[28399]: <<< dnNormalize: <uid=user1,ou=people,dc=example,dc=com> Jun 7 11:30:50 ldap1 slapd[28399]: ==>slap_sasl2dn: converting SASL name uid=user1,ou=people,dc=example,dc=com to a DN Jun 7 11:30:50 ldap1 slapd[28399]: slap_authz_regexp: converting SASL name uid=user1,ou=people,dc=example,dc=com Jun 7 11:30:50 ldap1 slapd[28399]: <==slap_sasl2dn: Converted SASL name to <nothing> Jun 7 11:30:50 ldap1 slapd[28399]: parseProxyAuthz: conn=135 "uid=user1,ou=people,dc=example,dc=com" Jun 7 11:30:50 ldap1 slapd[28399]: ==>slap_sasl_authorized: can uid=host/ldap2.example.com,cn=gssapi,cn=auth become uid=user1,ou=people,dc=example,dc=com?
