Setup OpenLDAP server for User Authentication
Contents
Objectives
OpenLDAP Server and client Configuration File
- /etc/openldap/slapd.conf
- Standalone OpenLDAP server configuration file
- You should set/modify the following directives
- rootdn - DN of the LDAP server administrator account
- rootpw - password for the administrator account
- database - what back end database to use
- suffix - the DN of the base directory on the LDAP server
- directory - where to put the database
- /etc/openldap/ldap.conf
- This is the configuration file for the ldap clients. The following are ldap client programs:
- ldapadd
- ldapcompare
- ldapdelete
- ldapmodify
- ldapmodrdn
- ldappasswd
- ldapsearch
- ldapwhoami
- You could set/modify the following directives:
- BASE
- URL
- This is the configuration file for the ldap clients. The following are ldap client programs:
- /etc/ldap.conf
- This is the configuration file for the LDAP nameservice switch library and the LDAP PAM module
- You could set/modify the following directives:
- base
- host - IP or hostname of the LDAP server. If you use hostname, it must be resolvable without using LDAP. Multiple hosts may be specified, each separated by a space.
Important LDAP Commands and Sample LDIF files
- Base LDIF file
- POSIX User account file
- ldapadd, ldapsearch, ldapdelete command
Tools/Utilities for Testing OpenLDAP Server
- ldapsearch
- To display LDAP Protocol features and extensions supported by OpenLDAP, use the following ldapsearch examples:
[rchan@moodle ~]$ ldapsearch -x -b "" -s base supportedFeatures # extended LDIF # # LDAPv3 # base <> with scope baseObject # filter: (objectclass=*) # requesting: supportedFeatures # # dn: supportedFeatures: 1.3.6.1.1.14 supportedFeatures: 1.3.6.1.4.1.4203.1.5.1 supportedFeatures: 1.3.6.1.4.1.4203.1.5.2 supportedFeatures: 1.3.6.1.4.1.4203.1.5.3 supportedFeatures: 1.3.6.1.4.1.4203.1.5.4 supportedFeatures: 1.3.6.1.4.1.4203.1.5.5 # search result search: 2 result: 0 Success # numResponses: 2 # numEntries: 1

Tools to test the LDAP server
- ldapsearch -x -W -D 'cn=Manager,dc=ops535,dc=com' -b "" -s base
Enter LDAP Password: # extended LDIF # # LDAPv3 # base <> with scope baseObject # filter: (objectclass=*) # requesting: ALL # # dn: objectClass: top objectClass: OpenLDAProotDSE # search result search: 2 result: 0 Success # numResponses: 2 # numEntries: 1
Using OpenLDAD for Apache Basic Authentication
- In httpd.conf configure the directory for basic authentication for apache 2.0
<Directory /var/www/html/openldap> AuthType Basic AuthName "Case Network ID" AuthLDAPURL "ldap://127.0.0.1/ou=people,dc=fedora,dc=directory,dc=server" AuthLDAPBindDN "uid=root,ou=people,dc=fedora,dc=directory,dc=server" AuthLDAPBindPassword "your-openldap-password" # All users in openldap require valid-user # Just the listed user # require user pma </Directory>
- For apache 2.2
<Location /var/www/html/openldap> AuthType Basic AuthBasicProvider ldap AuthName "Case Network ID" AuthzLDAPAuthoritative off AuthLDAPURL ldap://127.0.0.1/ou=people,dc=fedora,dc=directory,dc=server AuthLDAPBindDN "uid=root,ou=people,dc=fedora,dc=directory,dc=server" AuthLDAPBindPassword "your-openldap-password" Require valid-user </Location>
