The foundations for providing secure access to information and rich personalized experiences are based on authentication and permissions. Most organizations have existing personnel databases and related authentication mechanisms already in place. Two-factor authentication is very common in the financial sector. The portal platform must be able to integrate with these authentication environments. Some common identity management platforms that are supported by Liferay Enterprise Portal include:
-LDAP Authentication and Synchronization
-Oracle Access Manager
-Novell Identity Manager
-Sun Identify Manager/Open SSO
Tying any of the above identity management systems into Liferay is a matter of configuration rather than programming. If you have a non-standard identity management system, understanding the portal platform security architecture will be necessary. In the case of Liferay, there is a straightforward mechanism available for hooking into external authentication systems in a “shim-like” fashion.
