Hi, I would like to set up a OpenLDAP proxy with meta-backend. I have a test environment with two windows 2019 ADs and one OpenLDAP-server configured as proxy. At the beginning all the authentication are med with admin-accounts, it's the first step just testing. Here is my slapd.conf: ----------------------- Include /etc/ldap/schema/core.schema Include /etc/ldap/schema/corba.schema include /etc/ldap/schema/cosine.schema include /etc/ldap/schema/duaconf.schema include /etc/ldap/schema/dyngroup.schema include /etc/ldap/schema/inetorgperson.schema include /etc/ldap/schema/java.schema include /etc/ldap/schema/misc.schema include /etc/ldap/schema/nis.schema include /etc/ldap/schema/openldap.schema include /etc/ldap/schema/collective.schema include /etc/ldap/schema/pmi.schema include /etc/ldap/schema/ppolicy.schema pidfile         /var/run/slapd/slapd.pid argsfile        /var/run/slapd/slapd.args # Load dynamic backend modules: modulepath      /usr/lib/ldap moduleload      rwm.la moduleload      back_meta.la moduleload      back_ldap.la loglevel 4095 ####################################################################### # MDB database definitions ####################################################################### database meta suffix "dc=example,dc=de" rootdn "cn=admin,dc=example,dc=de" rootpw secret uri "ldap://192.168.56.201/ou=firma-01,dc=example,dc=de" readonly yes lastmod off suffixmassage "ou=firma-01,dc=example,dc=de" "ou=firma-01,dc=dom01,dc=example,dc=net" map attribute uid sAMAccountName idassert-bind bindmethod=simple     binddn="cn=administrator,cn=Users,dc=dom01,dc=example,dc=net"     credentials="Passw0rd" idassert-authzFrom "*" uri "ldap://192.168.56.202/ou=firma-02,dc=example,dc=de" readonly yes lastmod  off suffixmassage "ou=firma-02,dc=example,dc=de" "ou=firma-02,dc=dom02,dc=example,dc=com" map attribute uid sAMAccountName idassert-bind bindmethod=simple       binddn="CN=Administrator,CN=Users,DC=dom02,dc=example,DC=com"       credentials="Passw0rd" idassert-authzFrom "*" ----------------------- on my proxy I can do a "ldapsearch -x " and I can see all the wanted entries from both ADs. This is my ldap.conf on the proxy: ----------------------- BASE dc=example,dc=de URI ldap://192.168.56.210 ----------------------- 192.168.56.210 is my proxy. But now I would like to connect a client to the proxy to get the entries. The ldap.conf file is the same as on the proxy. But what ever I try I got now result. ---------------------- root@proxy-client:~# ldapsearch -x -D cn=admin,dc=example,dc=de -W  -LLL No such object (32) root@proxy-client:~# ldapsearch -x -LLL No such object (32) ---------------------- What am I missing? Thank's for any help Stefan
