  What is authentication? - a definition from Whatis.com - see also: authenticate
- Authentication is the process of determining whether someone or something is, in fact, who or what it is declared to be.
In private and public computer networks (including the Internet), authentication is commonly done through the use of logon passwords.
Logically, authentication precedes authorization (although they may often seem to be combined).

In computer security, Authentication is the process by which a computer, computer program, or another user attempts to confirm that the computer, computer program, or user from whom the second party has received some communication is, or is not, the claimed first party.
The problem of authorization is often considered to be identical to that of authentication: however, there are many cases in which these two problems are different.
It is not known whether these cryptographically based authentication methods are provably secure since unanticipated mathematical developments may make them vulnerable to attack in future.

 Authentication Encyclopedia Article @ ColorfulImaginations.com (Colorful Imaginations)   (Site not responding. Last check: )
Authentication (Greek: αυθεντικός = real or genuine, from 'authentes' = author) is the act of establishing or confirming something (or someone) as authentic, that is, that claims made by or about the thing are true.
Authenticating an object may mean confirming its provenance, whereas authenticating a person often consists of verifying their identity.
In computer security, authentication is the process of attempting to verify the digital identity of the sender of a communication such as a request to log in.

 Authentication
Authentication tools provide the ability to determine the identity of a party to an interaction and to ensure that a message came from who it claims to have come from.
Authentication is used as the basis for authorization (determining whether a privilege will be granted to a particular user or process), privacy (keeping information from becoming known to non-participants), and non-repudiation (not being able to deny having done something that was authorized to be done based on the authentication).
Instead, an "authentication server" creates a collection of "session secrets" (derived from its knowledge of the secrets of the sender and receiver in a particular interchange) that are used by the sender and receiver for authentication of messages during a particular interaction.

 Authentication
Authentication is one of the most powerful features offered by the KeyServer Package, but it is also one of its most complex.
Other authentication methods that distinguish one user from another can be used to set up groups of users, and then different license pools can be assigned to groups within each Control.
Authentication methods are stored in separate modules, which must be stored in the Authentication Methods folder within the KeyServer Data Folder in order to be accessible to the KeyServer.

 Authentication - CryptoDox
Authentication is different from authorization; which is the process of giving individuals access to system objects based on their identity.
Authentication merely ensures that the individual is who he or she claims to be, but says nothing about the access rights of the individual.
Instead, an "authentication server" creates a collection of "session secrets" that are used by the sender and receiver for authentication of messages during a particular interaction.

 RFC 2941 (rfc2941) - Telnet Authentication Option   (Site not responding. Last check: )
The purpose of the AUTHENTICATION option is to provide a framework for the passing of authentication information through the TELNET session, and a mechanism to enable encryption of the data stream as a side effect of successful authentication or via subsequent use of the telnet ENCRYPT option.
Requesting authentication information may be done as a way of verifying the validity of the client's credentials after an extended period of time or to negotiate a new session key for use during encryption.
The actual authentication mechanism is described in the authentication suboption specifications, and the security of the authentication option is dependent on the strengths and weaknesses of the authentication suboption.

 Controlling Access to the Switch Using Authentication   (Site not responding. Last check: )
Authentication configuration applies both to console and Telnet connection attempts unless you use the console and telnet keywords to specify the authentication methods to use for each connection type individually.
After a user authenticates to the switch using Kerberos and wants to Telnet to another switch or host, whether this will be a Kerberized Telnet depends on the authentication method that the Telnet server uses.
Any authentication requests received during the deadtime interval (such as other users attempting to login to the switch) are not sent to a RADIUS server marked dead.

 Authentication, Authorization and Access Control - Apache HTTP Server
Authentication is any process by which you verify that someone is who they claim they are.
Because of the way that Basic authentication is specified, your username and password must be verified every time you request a document from the server.
Authentication by username and password is only part of the story.

 Authentication, Authorization, and Access Control
Authentication is equivalent to showing your drivers license at the ticket counter at the airport.
As with basic authentication, a simple utility is provided to create and maintain the password file which will be used to determine whether a particular user's name and password are valid.
And so every time a document is accessed which is secured with basic or digest authentication, Apache has to open up those text password files and look through them one line at a time, until it finds the user that is trying to log in, and verifies their password.

 Authentication
For the duration of the authentication, the user's name is tied to connections originating from the IP address from which the user authenticated.
The differences among the various authentication schemes are largely transparent to the user; the user performs the same sequence of tasks to be authenticated against any of the four types of authentication.
When users authenticate using their account in the Firebox Domain, WatchGuard automatically adds their IP address to all Firebox Domain groups of which they are a member (and conversely removed when they end their authentication).

 PostgreSQL: Documentation: Manuals: PostgreSQL 8.0: Client Authentication
Authentication is the process by which the database server establishes the identity of the client, and by extension determines whether the client application (or the user who runs the client application) is permitted to connect with the user name that was requested.
The method used to authenticate a particular client connection can be selected on the basis of (client) host address, database, and user.
It is possible to place the authentication configuration file elsewhere, however; see the hba_file configuration parameter.

 Welcome to the E-Authentication site
Control costs associated with authenticating the identity of a large number of end users by eliminating the need for each agency to create and maintain a separate credentialing system for each of their online applications.
The policy issued by OMB in Memorandum M-04-04 and by the National Institute of Standards and Technology in Special Publication 800-63 (NIST SP 800-63), and industry standards such as the Security Assertion Markup Language (SAML), form the foundation of the Federation.
Together these foundational pieces provide agencies a policy-compliant and standards-based framework for authentication and identity services that enable the reuse of identity credentials across government applications.

 Django | Documentation | User authentication in Django
The authentication that comes with Django is good enough for most common cases, but you may have the need to hook into another authentication source -- that is, another source of usernames and passwords or authentication methods.
If the first authentication method fails, Django tries the second one, and so on, until all backends have been attempted.
is_authenticated() is not an available method on AnonymousUser, so you can't use it in each webrequest.
