Overview#
LDAP is an Abbreviation of Lightweight Directory Access Protocol which is a Protocol.However, most of our references will use LDAP
LDAP or LDAP is a protocol that may be used to communicate with a DSA.
LDAP is an open standard that uses the Basic Encoding Rules (Basic Encoding Rules) subset of ASN.1 to encode communication for each LDAP Message.
LDAP is a request-response type of protocol where each request is followed by a response.
There are several LDAP Protocol Exchanges which can be one or more request and zero or more responses
An Introduction to LDAP #
An Introduction to LDAP for basic information.Some Views on LDAP#
LDAP Result Codes #
Remember, LDAP is simple, there is a limited number of server LDAP Result Codes.LDAP Searches #
As LDAP Searches are the most common interaction in LDAP, we have a LOT of information on the subject.LDAP Server Implementations #
LDAP servers, or DSA are available form several sources as LDAP Server ImplementationsLDAP Browsers #
The most common LDAP Client or DUA is the LDAP Browsers. We have a list of the LDAP Browsers we know about.Why LDAP is Important #
Why we think LDAP is Important. As primarily folks that integrate with many systems, we see the ins and outs of communication with many different types of systems on a daily basis.LDAP Best Practices#
