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： A domain controller (DC) side plugin supports one time passwords natively in Kerberos, Part of the key material is static and the other part is dynamic, thereby leveraging properties unique to each to securely support one time passwords in an operating system. The user is permitted to type in the one time passcode into a logon user interface. Rather than calling the SAM APIs to get the static passwords, vendors may register callbacks on the DC to plugin their algorithm. These callback functions will return the dynamically calculated passcodes for the user at a specific point in time. This passcode will then be treated as a normal password by the DC.

摘要： Systems and methods for negotiating an encryption algorithm may be implemented in the context of encryption-based authentication protocols. The invention has the added benefit of providing a system an method that need not interfere with the standard operation of authentication protocols. A first computer, or client computer, can send a negotiation request to a second computer, or server computer. The negotiation request can specify that the client computer supports a selected encryption algorithm. In response, the server computer can return a subsession key for encryption using the selected encryption algorithm. Both client and server may then switch to encryption in the selected encryption algorithm, using the subsession key to encrypt future communications.

摘要： NTLM compliant clients and servers are mutually authenticated in accordance with the Kerberos authentication protocol without migrating the clients or servers to Kerberos. With an RPC framework, a target name is generated from the server host name. The target name includes an indication that mutual authentication is to be accomplished. During the initial stages of the RPC session, the target name is sent to the server. If the server recognizes the target name, the client and server are mutually authenticated in accordance with the Kerberos protocol. If the server does not recognize the target name, the client is authenticated in accordance with the NTLM authentication protocol.
