LDAP Directory Information

LDAP Directory Information esembrat3
Drupal Version

Lightweight Directory Access Protocol (LDAP) is an open protocol for sharing directory information and can be used as an alternative to CAS to allow users to log in to a web application using their GT Account Username and password.  Unless your application doesn't support CAS, it's best to use it instead of LDAP, since LDAP requires obtaining a special GTED LDAP user account for your application.

If you just want basic directory information for users without the ability to do user authentication, there is a public GT LDAP server called 'Whitepages' that can be queried from any server or workstation on-campus.
