Setting up LDAP with Shibboleth Idp 2.4.0

Farrukh,

It's your choice whether authentication happens via an anonymous BIND or via a search by an authenticated DN.  The LDAP login module supports both.

In order to retrieve attributes about the user from a directory, the IdP will need a privileged user account to perform the search.

Thanks,
Nate.

I am wondering ifmy authentication problem with my ldap server is due to my not specifying bindDN and bindCredential in my edu.vt.middleware.ldap.jaas.LdapLoginModule configuration.

My Ldap server does not have a privileged user to create the connection with. Thus I do not specify bindDN and bindCredential in my edu.vt.middleware.ldap.jaas.LdapLoginModule configuration.

Is this the correct thing to do in my situation?

FWIW, The same config works fine in my webapp using spring-security.

    <bean id="contextSource" class="org.springframework.security.ldap.DefaultSpringSecurityContextSource">
        <constructor-arg value="ldap://localhost:33389/dc=springframework,dc=org"<ldap://localhost:33389/dc=springframework,dc=org>/>
    </bean>

    <bean id="userSearch" class="org.springframework.security.ldap.search.FilterBasedLdapUserSearch">
      <constructor-arg index="0" value=""/>
      <constructor-arg index="1" value="(uid={0})"/>
      <constructor-arg index="2" ref="contextSource" />
    </bean>

Any suggestions what else could I try?

I have been unsuccessful thus far in setting up IdP 2.4.0 with my test ldap server (spring-security-ldap-sample).

I have made the following config changes by adding config elements shown for each file below:


  *
conf/login.config

edu.vt.middleware.ldap.jaas.LdapLoginModule required
  ldapUrl="ldap://localhost:33389/dc=springframework,dc=org"<ldap://localhost:33389/dc=springframework,dc=org>
  baseDn=""
  ssl="false"
  userFilter="uid={0}";
};

  *
conf/handler.xml

    <!--  Username/password login handler -->
    <ph:LoginHandler xsi:type="ph:UsernamePassword"
                 jaasConfigurationLocation="file:///home/najmi/shibboleth/shibboleth-identityprovider-2.4.0/installation/conf/login.config"<file:///home/najmi/shibboleth/shibboleth-identityprovider-2.4.0/installation/conf/login.config>>
       <ph:AuthenticationMethod>urn:oasis:names:tc:SAML:2.0:ac:classes:PasswordProtectedTransport</ph:AuthenticationMethod>
    </ph:LoginHandler>

I then try and login at the idp/login.jsp page with well-known credentials. I get the error below.
ERROR

An error occurred while processing your request. Please contact your helpdesk or user ID office for assistance.

Error Message: Invalid IdP URL (HTTP 404)

Also, I notice that the login.jsp code "Log in to <idpui:serviceName/>"

renders as "Log in to Unspecified Service Provider". I guess this is telling that my config for the ldap provider is not being read for some reason.

I have done no customization of the login.jsp page beyond changing the logo.
What could be wrong and how can I debug this better.

TIA for your kind help.
