AuthenticationSchemes Enumeration
Specifies protocols for authentication.
This enumeration has a FlagsAttribute attribute that allows a bitwise combination of its member values.
Namespace: System.NetAssembly: System (in System.dll)
| Member name | Description | |
|---|---|---|
| None | No authentication is allowed. A client requesting an HttpListener object with this flag set will always receive a 403 Forbidden status. Use this flag when a resource should never be served to a client. | |
| Digest | Specifies digest authentication. For additional information, see RFC2617 – HTTP Authentication: Basic and Digest Authentication. This document is available at http://www.rfc-editor.org | |
| Negotiate | Negotiates with the client to determine the authentication scheme. If both client and server support Kerberos, it is used; otherwise, NTLM is used. | |
| Ntlm | Specifies NTLM authentication. | |
| Basic | Specifies basic authentication. For additional information, see RFC2617 – HTTP Authentication: Basic and Digest Authentication. This document is available at http://www.rfc-editor.org. | |
| Anonymous | Specifies anonymous authentication. | |
| IntegratedWindowsAuthentication | Specifies Windows authentication. |
This enumeration is used to specify the method used to authenticate client requests being processed by HttpListener objects.
Note Basic authentication requires the exchange of a password and should therefore be avoided except in the case of secure, encrypted connections.
