glossaryThis article describes briefly what it is and what it's used for.


What is LDAP?

LDAP the Lightweight Directory Access Protocol, is a way of centrally storing information in a heirarchical way.  It is most commonly used by authentication servers to allow users to log on to various machines using the same credentials.

  • OpenLDAP is the open source alternative.


Which version of LDAP should you use?

  • If you have exclusively Windows XP clients, you can use both OpenLDAP and Active Directory.
  • If you have Windows, Linux and Mac OSX clients, Active Directory is your best bet.
