摘要： This disclosure describes methods, systems and application programming interfaces for creating an advanced security negotiation package. This disclosure describes creating an advanced security negotiation protocol under a Simple and Protected Negotiation Mechanism (SPNEGO) protocol to negotiate an authentication scheme. The protocol describes defining a Windows Security Type (WST) Library message to protect negotiation data during the advanced security negotiation protocol. The protocol sends an initial message that carries multiple authentication messages to reduce redundant roundtrips and implements key exchanges by a mini Security Support Provider (SSP).

摘要： Architecture for natively authenticating a client application to a web server via HTTP authentication. The Web Services Architecture, and more specifically, Web Services Security, is leveraged to enable legacy applications to access web services transparently to the existing legacy applications. A security support provider (SSP) is created that employs WS-* protocol to at least emulate ws-trust and ws-mex thereby enabling policy exchange via an HTTP protocol stack. Policy can be exchanged via a WWW-Authenticate header enabling legacy applications to use the WS-* family of protocols without modifying the client application. The WS-* protocols are abstracted into a generic programming interface for native client application use.

摘要： Remote administrative privileges in a distributed system are disabled by default. To administer a remote system, express action is taken to elevate a user status to obtain remote administrative privileges. When local and remote systems communicate, information pertaining to the status of the logged on user is included in the communications. If the user wishes to legitimately administer a remote system, the user provides an explicit request. The request is processed. If the user is configured as an administrator of the remote system and the request contains an indication that the user's administrative status has been elevated, an authorization token is generated. The authorization token is utilized by the remote system to allow the user to administer the remote system.

摘要： A hint containing user mapping information is provided in messages that may be exchanged during authentication handshakes. For example, a client may provide user mapping information to the server during authentication. The hint (e.g., in the form of a TLS extension mechanism) may be used to send the domain/user name information of a client to aid the server in mapping the user's certificate to an account. The extension mechanism provides integrity and authenticity of the mapping data sent by the client. The user provides a hint as to where to find the right account or domain controller (which points to, or otherwise maintains, the correct account). Based on the hint and other information in the certificate, the user is mapped to an account. The hint may be provided by the user when he logs in. Thus, a certificate is mapped to an identity to authenticate the user. A hint is sent along with the certificate information to perform the binding. Existing protocols may be extended to communicate the additional mapping information (the hint) to perform the binding. A vendor specific extension to Kerberos is defined to obtain the authorization data based on an X.509 certificate and the mapping user name hint.

摘要： Modern network communications often require a client application requesting data to authenticate itself to an application providing the data. Such authentication requests can be redundant, especially in the case of stateless network protocols. When a full authentication is performed, a conversation identifier and one or more encryption keys can be agreed upon. Subsequent authentication requests can be answered with a fast reconnect token comprising the conversation identifier and a cryptographically signed version of it using the one or more encryption keys. Should additional security be desirable, a sequence number can be established and incremented in a pre-determined or a random manner to enable detection of replayed fast reconnect tokens. If the recipient can verify the fast reconnect token, the provider can be considered to have been authenticated based on the prior authentication. If an aspect of the fast re-authentication should fail, recourse can be had to the original full authentication process.

摘要翻译： 现代网络通信通常需要客户端应用程序请求数据对提供数据的应用程序进行身份验证。 这种认证请求可以是冗余的，特别是在无状态网络协议的情况下。 当执行完整认证时，可以同意会话标识符和一个或多个加密密钥。 随后的认证请求可以用包括会话标识符的快速重新连接令牌和使用该一个或多个加密密钥的加密签名版本来应答。 如果需要额外的安全性，则可以以预定或随机的方式建立和递增序列号，以便能够检测重放的快速重新连接令牌。 如果收件人可以验证快速重新连接令牌，则可以认为提供商已经根据先前的身份验证进行了身份验证。 如果快速重新认证的一个方面应该失败，则可能需要对原始的完整身份验证过程进行追索。

摘要： A client can communicate with a middle tier, which can then, in turn, communicate with a back end tier to access information and resources on behalf of the client within the context of a system that can scale well. Each individual back end can establish a policy that defines which computing device can delegate to that back end. That policy can be enforced by a domain controller within the same administrative domain as the particular back end. When a middle tier requests to delegate to a back end, the domain controller to which that request was directed can either apply the policy, or, if the domain controller is in a different domain than the targeted back end, it can direct the middle tier to a domain controller in a different domain and can sign relevant information that the middle tier can utilize when communicating with that different domain controller.

摘要翻译： 客户端可以与中间层进行通信，然后可以与后端层进行通信，以便在可以扩展的系统的上下文中代表客户端访问信息和资源。 每个单独的后端可以建立一个策略，定义哪个计算设备可以委托给该后端。 该策略可以由与特定后端相同的管理域中的域控制器实施。 当中间层请求委托给后端时，该请求所针对的域控制器可以应用策略，或者如果域控制器位于与目标后端不同的域中，则可以将中间层 到不同域中的域控制器，并且可以签署中间层在与该不同域控制器通信时可以利用的相关信息。
