titleAttribute Retrieval

LDAP attributes are returned as part of the authentication process and exposed in the LDAPResponseContext.

Property

Sample

Result

idp.authn.LDAP.returnAttributes

uid,

eduPersonAffiliation

Returns the uid and

eduPersonAffiliation attributes.

*

Returns all user attributes on the entry.

*,+

Returns all user and operational attributes on the entry.

1.1

No attribute returned. No search performed.

By default, attributes will be searched for using the same connection the user authenticated on. Therefore the user must have read on any attributes for those to be returned.

If you need access to attributes that user does not have read access to, then you must configure a connection pool that is authorized to read that data. The following configuration demonstrates how to add a new connection pool for that purpose.

            <constructor-arg value="%{idp.authn.LDAP.entryResolver.bindDNCredential}" />
        </bean>
    </property>
</bean>

Add the idp.authn.LDAP.entryResolver.bindDN and idp.authn.LDAP.entryResolver.bindDNCredential properties to conf/ldap.properties and credentials/secrets.properties respectively. Then set idp.authn.LDAP.authenticator to anonSearchAuthenticator. to complete the configuration.

Note: if you're using the bindSearchAuthenticator and those credentials can be reused for entry resolution, then this configuration can be shortened by wiring the bindPooledConnectionFactory to the entry resolver.

This example is likely not correct yet, needs expert review

titleDN Resolution

Single Directory with Multiple Branches

Extensible Matching

If your directory supports extensible matching, this is the easiest way to find users that are distributed over multiple branches.

Property

Value

Result

idp.authn.LDAP.userFilter

(&(|(ou:dn:=people)(ou:dn:=guests))(uid={user}))

Returns the entry that matches uid on either the people or guests branch.

idp.authn.LDAP.baseDN

dc=example,dc=org

The branch containing both ou=people and ou=guests.

idp.authn.LDAP.subtreeSearch

true

Enable subtree searching on the dc=example,dc=org branch.

Aggregate DN Resolver

This authenticator combines the results of multiple DN resolvers.

Add the idp.authn.LDAP.baseDN[12] and idp.authn.LDAP.userFilter[12] properties to conf/ldap.properties. The key values used in dnResolvers and authHandlers can be anything, but must tie a single DN resolver to a single auth handler. By default an error will occur if more than (1) DN is resolved.

In addition to these beans, the aggregateAuthenticator bean (in the example above) must be injected into the LDAP credential validator in password-authn-config.xml:

Code Block
<util:list id="shibboleth.authn.Password.Validators">
    <!-- Default bean uses the settings defined in ldap.properties -->
    <bean parent="shibboleth.LDAPValidator" p:authenticator-ref="aggregateAuthenticator" />
