These instructions document how to configure uPortal itself to perform authentication against LDAP. It is also possible to configure the bundled CAS instance, or some other CAS server, to connect to LDAP instead of following this approach.
Step 1. Add the ldap connection context to uportal-war/src/main/resources/properties/contexts/ldapContext.xml
uportal-war/src/main/resources/properties/contexts/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>
Step 2. Add the SimpleLdapSecurityContextFactory to uportal-war/src/main/resources/properties/security.properties
uportal-war/src/main/resources/properties/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:
uportal-war/src/main/resources/properties/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.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
Step 3. (Optional) Show Login Form for Guest User
If using import scripts
There seems to be a bug in the import script that won't allow you to import the channel if the comment below is left in place in uportal-war/src/main/data/default_entities/layout/guest.layout.xml (https://issues.jasig.org/browse/UP-3176)
<!--Uncomment to use local login <channel fname="login" unremovable="false" hidden="false" immutable="false"/>-->
- In order to show the login form for the guest user layout, go to uportal-war/src/main/data/default_entities/layout/guest.layout.xml file and remove the comment to include the local login form. Your resulting guest.layout.xml file should look like the code segment below without the comment:
uportal-war/src/main/data/default_entities/layout/guest.layout.xml
<layout xmlns:dlm="http://www.uportal.org/layout/dlm" script="classpath://org/jasig/portal/io/import-layout_v3-2.crn" username="guest">
<folder hidden="false" immutable="false" name="Root folder" type="root" unremovable="true">
<folder hidden="false" immutable="true" name="Header folder" type="header" unremovable="true">
<channel fname="login" unremovable="false" hidden="false" immutable="false"/>
</folder>
<folder hidden="false" immutable="false" name="Footer folder" type="footer" unremovable="false"/>
</folder>
</layout>
Step 4. Build and deploy the modifications
From the root of your uPortal distribution (i.e., /uPortal-4.x), execute the following command:
ant clean deploy-war
