LDAP Directory
MIT's LDAP Directory Service (ldap.mit.edu) is MIT's implementation of the standard LDAP protocol for providing directory services. It provides access to user and group membership information sourced from Moira and updated in real time, allowing application developers or administrators looking to integrate their applications with MIT's enterprise data.
As an example, wikis.mit.edu (based on Atlassian Confluence) makes use of the LDAP service for user lookups.
