!!! Overview [{$pagename}] ([QoP]) is a property of certain [SASL Mechanisms] (especially the [DIGEST-MD5] and [GSSAPI] mechanisms) that can be used to protect the communication between the client and the server. There are three different [QoP] levels: * auth -- This indicates that the associated [SASL Mechanisms] should only be used for [Authentication] of the client connection. It should not provide any other protection for the client-server communication * auth-int -- This indicates that the associated [SASL Mechanisms]m should be used for [authentication], and then should also provide [integrity] protection for the [communication] between the client and server. [Integrity] protection will not prevent third-party [observers] from understanding the communication, but it will ensure that a [man-In-The-Middle] is unable to alter that communication in an undetectable manner * auth-conf -- This indicates that the associated SASL mechanism should be used for [authentication], and then should also provide [integrity] and [confidentiality] protection for the [communication] between the client and the server. This will ensure that third-party [observers] will [NOT] be unable to understand the [communication] !!
