LDAP Enumeration

LDAP: Lightweight Directory Access Protocol

LDAP (Lightweight Directory Access Protocol) is a software protocol for enabling anyone to locate data about organizations, individuals and other resources such as files and devices in a network - whether on the public Internet or on a corporate Intranet.

LDAP is a "lightweight" (smaller amount of code) version of Directory Access Protocol (DAP), which is part of X.500, a standard for directory services in a network.

Ports

  • 389 : LDAP (regular)

  • 636 : LDAPs (LDAP over TLS/SSL)

  • 3268 : msft-gc, Microsoft Global Catalog (LDAP service which contains data from Active Directory forests)

  • 3269 : msft-gc-ssl, Microsoft Global Catalog over SSL (similar to port 3268, LDAP over SSL)
