These instructions document how to configure uPortal itself to perform authentication against LDAP. It is also possible to [configure the bundled CAS instance|http://www.ja-sig.org/wiki/x/ogvP], or some other CAS server, to connect to LDAP instead of following this approach.
Add the ldap connection context to ldapContext.xml
<bean id="defaultLdapServer" class="org.jasig.portal.ldap.ContextSourceLdapServerImpl">
<property name="ldapContextSource" ref="legacyLdapContext"/>
<property name="uidAttribute" value="uid"/>
<property name="baseDN" value="ou=People, dc=myuniv, dc=edu"/>
</bean>
<bean id="legacyLdapContext" class="org.springframework.ldap.core.support.LdapContextSource">
<property name="url" value="ldap://ldap.myuniv.edu:389"/>
<property name="userName" value=""/>
<property name="password" value=""/>
</bean>
Add the SimpleLdapSecurityContextFactory to security.properties
## This is the factory that supplies the concrete authentication class root=org.jasig.portal.security.provider.UnionSecurityContextFactory root.simple=org.jasig.portal.security.provider.SimpleSecurityContextFactory root.ldap=org.jasig.portal.security.provider.SimpleLdapSecurityContextFactory
If you need to uPortal to cache user passwords, you may add the cache security context factory:
## This is the factory that supplies the concrete authentication class root=org.jasig.portal.security.provider.UnionSecurityContextFactory root.simple=org.jasig.portal.security.provider.SimpleSecurityContextFactory root.simple.cache=org.jasig.portal.security.provider.CacheSecurityContextFactory root.ldap=org.jasig.portal.security.provider.SimpleLdapSecurityContextFactory root.ldap.cache=org.jasig.portal.security.provider.CacheSecurityContextFactory
