The Lightweight Directory Access Protocol (LDAP / ˈ ɛ l d æ p /) is an open, vendor-neutral, industry standard application protocol for accessing and maintaining distributed directory information services over an Internet Protocol (IP) network. [1]
The term channel binding describes the man-in-the-middle attack prevention strategy to 'bind' an application layer, which provides mutual authentication, to a lower (mostly encryption) layer, ensuring that the endpoints of a connection are the same in both layers. There are two general directions for channel binding: unique and endpoint channel ...
The notion of binding is not fully developed until SAML 2.0. SAML 2.0 completely separates the binding concept from the underlying profile. In fact, there is a brand new binding specification in SAML 2.0 that defines the following standalone bindings: SAML SOAP Binding (based on SOAP 1.1) Reverse SOAP (PAOS) Binding; HTTP Redirect (GET) Binding
SAML assertions contain statements that service providers use to make access control decisions. For instance, authentication statements assert to the service provider that the principal did indeed authenticate with the identity provider at a particular time using a particular method of authentication.
For example, slapd (the standalone LDAP daemon) generally runs as a non-root user, and SASL-based encryption of LDAP traffic is natively supported. On large LANs, DNS servers may provide better nameserver functionality than NIS or LDAP can provide, leaving just site-wide identification information for NIS master and slave systems to serve ...
Token Binding is a proposed standard for a Transport Layer Security (TLS) extension that aims to increase TLS security by using cryptographic certificates on both ends of the TLS connection. Current practice often depends on bearer tokens, [ 1 ] which may be lost or stolen.
Simple Authentication and Security Layer (SASL) is a framework for authentication and data security in Internet protocols.It decouples authentication mechanisms from application protocols, in theory allowing any authentication mechanism supported by SASL to be used in any application protocol that uses SASL.
Security Assertion Markup Language 2.0 (SAML 2.0) is a version of the SAML standard for exchanging authentication and authorization identities between security domains.SAML 2.0 is an XML-based protocol that uses security tokens containing assertions to pass information about a principal (usually an end user) between a SAML authority, named an Identity Provider, and a SAML consumer, named a ...
