Introduction #

The purpose of this document is to explain how to integrate NTLM Single Sign-On (SSO) into the Liferay portal with an example. By default, the portal uses its own authorization, i.e. user name and password, to identify a user. Liferay portal supports external authorization methods like Lightweight Directory Access Protocol (LDAP) to any compliant LDAP database as well as a Central Authorization Service (JA-SIG CAS), OpenID, and OpenSSO, Computer Associate’s (CA) Siteminder.

Overview #

Suppose that you have a server: Microsoft Active Directory Server (ADS) with IP e.g. 192.168.2.230 and a domain, e.g., cignex.net. By default, the port number is 389.

Users and groups are in CN=Users,DC=CIGNEX,DC=NET

The administrator: CN=Administrator,CN=Users,DC=CIGNEX,DC=NET

We are planning to integrate this NTLM in Liferay portal.

ADS Settings #

Default settings #

Check the checkbox Enabled.

Check the checkbox Required.

Select Microsoft Active Directory Server.

Connection #

Connect to the ADS server

Base Provider URL: for example, ldap://192.168.2.230:389.

Base DN: for example, CN=Users,DC=CIGNEX,DC=NET

Principal: for example, CN=Administrator,CN=Users,DC=CIGNEX,DC=NET

Credentials: the password of the Administrator.

Users Mapping #

Note: use Authentication Search Filter: (cn=@screen_name@) for screenName login

Groups Mapping #

Import and Export #

Save when you are ready.

NTLM Settings #

Check the checkbox Enabled.

Input Domain Controller: for example, cignex.net.

Input Domain: e.g., 192.168.2.230.

Note that the server (where Liferay portal installed) must have access on the domain by the domain controller.

You should get similar screenshot as follows.
