Hi! I'm migrating from OpenLDAP to Fedora Directory. In the OpenLDAP infrastructure, I had used proxy LDAP servers (the slapd-ldap backend) to direct requests to slapd-bdb backend OpenLDAP instances with failover in case of failure. In addition to that, using the rwm overlay, the slapd-ldap instance did request rewriting of queries that specify empty base dn. The configuration for slapd-ldap instance was: database ldap suffix "" uri "ldap://localhost:392/,ldaps://otherserver:636/" timeout 24 idle-timeout 16 overlay rwm rwm-rewriteEngine on rwm-rewriteContext searchBase rwm-rewriteRule "$" "o=MyDefaultBase" ":" I've read a thread from 2006-02 on this list (https://www.redhat.com/archives/fedora-directory-users/2006-February/msg00108.html) that it's possible to get a similar behaviour on FDS by modifying dse.ldif. I've stopped the FDS instance, modified /etc/dirsrv/slapd-instancename/dse.ldif and started FDS again: dn: objectClass: top objectClass: extensibleObject defaultsearchbase: o=MyDefaultBase aci: (targetattr != "aci")(version 3.0; aci "rootdse anon read access"; allow( read,search,compare) userdn="ldap:///anyone";) creatorsName: cn=server,cn=plugins,cn=config modifiersName: cn=server,cn=plugins,cn=config createTimestamp: 20080411165538Z modifyTimestamp: 20080411165538Z However, it still doesn't return anything when clients search with empty base: # /usr/lib64/mozldap/ldapsearch -b 'o=MyDefaultBase' -s sub uid=olo uid version: 1 dn: uid=olo,ou=People,o=MyDefaultBase uid: olo # /usr/lib64/mozldap/ldapsearch -b '' -s sub uid=olo uid ldap_search: No such object Maybe it's relevant that the host in question takes part in multi-master replication setup of 3 FDS servers. -- Best Regards, Aleksander Adamowski GG#: 274614 ICQ UIN: 19780575 http://olo.org.pl -- Aleksander Adamowski Administrator system?w korporacyjnych; Instruktor Altkom Akademia S.A. http://www.altkom.pl Warszawa, ul.
