Authentication server

An authentication server provides a <a href="/facts/Network_service/GdLvd2ml">network service</a> that applications use to <a href="/facts/Authentication/64y4S69b">authenticate</a> the credentials, usually account names and passwords, of their users. When a client submits a valid set of credentials, it receives a <a href="/facts/Cryptographic/e94PEVau">cryptographic</a> ticket that it can subsequently use to access various services.
Authentication is used as the basis for <a href="/facts/Authorization/FYFAkCH2">authorization</a>, which is the determination whether a <a href="/facts/Privilege_(computing)/7eS1wna4">privilege</a> may be granted to a particular user or <a href="/facts/Process_(computing)/Vcq7EnUV">process</a>, <a href="/facts/Privacy/C269YalS">privacy</a>, which keeps information from becoming known to non-participants, and <a href="/facts/Non-repudiation/uNAP1YIf">non-repudiation</a>, which is the inability to deny having done something that was <a href="/facts/Authorized/FYFAkCH2">authorized</a> to be done based on the <a href="/facts/Authentication/64y4S69b">authentication</a>.
Major authentication <a href="/facts/Algorithm/fnl5NmRt">algorithms</a> include <a href="/facts/Password/WEoul230">passwords</a>, <a href="/facts/Kerberos_(protocol)/RMXs3P1w">Kerberos</a>, and <a href="/facts/Public_key_encryption/gowoFTxS">public key encryption</a>.
