Using an Enterprise Directory Service
Instead of using the Windchill Directory Server that is bundled with your Windchill solution for the end users in the Enterprise LDAP service, you can use an enterprise directory service such as the Microsoft Active Directory Service (ADS). Each enterprise directory service entry contains attributes for the user. For example, user entries can have attributes for the user’s full name, email address, and organization.
The installation process can set up the enterprise directory service as the Enterprise LDAP node. If this was not done, an additional directory service can be established that uses the enterprise directory service.
Usually, users in an enterprise directory service are managed through a third party tool and the Windchill user database object is created automatically the first time the user logs into the Windchill solution.
