Hi, I am new to LDAP. Hence kindly do excuse if any of my terminology is different. Issue: ----- I installed the openldap server through debian package. ie. did NOT get the source. Was able to add the record and display them. ie. the slaptest worked fine and also could able to search the database with ldapsearch command also. Also able to start and stop the daemon. But i am having an issue regarding the retrieval of authFilterId attribute stored in the LDAP database. Is authFilterId and FilterId attribute same?? Tried to retrieve both of them but unable to get the values of the attribute. Added a schema by name auth.schema in the slapd.conf. This file was not present in the default installation of the openldap. The below are the details of the configuration: openldap server version: OpenLDAP: slapd 2.4.9 Operating System: Ubuntu 8.04 slapd.conf: # This is the main slapd configuration file.

This schema file added by me. It did not come in the default installation. This is required as my proprietary ldap client needs it. I am not sure of its exact use. but i guess its related to radius. attributetype ( 1.3.6.1.4.1.3317.4.3.1.9 NAME ( 'authFilterId' ) DESC 'radiusSchema: authFilterId' EQUALITY caseIgnoreIA5Match SYNTAX 1.3.6.1.4.1.1466.115.121.1.26 SINGLE-VALUE ) objectclass ( 2.16.840.1.113730.3.2.222 NAME 'auth' DESC 'Authentication database' SUP top STRUCTURAL MUST ( uid $ userPassword $ authFilterId)) ######################################################## end of auth.schema LDAP ldif file: init.ldif dn: dc=example,dc=com objectClass: dcObject objectClass: organizationalUnit dc: example ou: Example Dot Com dn: cn=admin,dc=example,dc=com objectClass: simpleSecurityObject objectClass: organizationalRole cn: admin description: LDAP administrator userPassword: secret123 dn: ou=people,dc=example,dc=com objectClass: organizationalUnit ou: people dn: ou=groups,dc=example,dc=com objectClass: organizationalUnit ou: groups dn: uid=fsmith,ou=people,dc=example,dc=com objectClass: inetOrgPerson objectClass: posixAccount objectClass: shadowAccount objectClass: radiusprofile uid: fsmith sn: Smith givenName: Fred cn: Fred Smith displayName: Fred Smith uidNumber: 1001 gidNumber: 1001 userPassword: secret123 gecos: Fred Smith loginShell: /bin/bash homeDirectory: /home/fsmith shadowExpire: -1 shadowFlag: 0 shadowWarning: 7 shadowMin: 8 shadowMax: 999999 shadowLastChange: 10877 mail: fsmith(a)example.com authFilterId: fsmith initials: FS Added the above records using the command: $ slapadd -l init.ldif Added successfully no errors on the command line. When i searched the database using the command $ ldapsearch -xLLL -b "dc=example,dc=com" '(objectclass=*)' I was able to see all the details present in the init.ldif file except the FilterId field: authFilterId: fsmith When i issue the command, $ ldapsearch -xLLL -b "dc=example,dc=com" '(objectclass=*)' '(authFilterId=*)' then also it does not display the authFilterId attribute. The slaptest when run in the debug level 16783 does not show any errors. The tail message of the slaptest o/p is: .... slaptest startup: initiated. backend_startup_one: starting "cn=config" config_back_db_open config_build_entry: "cn=config" config_build_entry: "cn=module{0}" config_build_entry: "cn=schema" config_build_entry: "cn={0}core" config_build_entry: "cn={1}cosine" config_build_entry: "cn={2}nis" config_build_entry: "cn={3}inetorgperson" config_build_entry: "cn={4}auth" config_build_entry: "olcDatabase={-1}frontend" config_build_entry: "olcDatabase={0}config" config_build_entry: "olcDatabase={1}hdb" backend_startup_one: starting "dc=example,dc=com" hdb_db_open: "dc=example,dc=com" hdb_db_open: database "dc=example,dc=com": dbenv_open(/var/lib/ldap). config file testing succeeded slaptest shutdown: initiated ====> bdb_cache_release_all slaptest destroy: freeing system resources. Kindly do suggest of how to retrieve the authFilterId attribute value. have a nice day, navin
