The client finds a computer account based on the SPN of the service to which it is trying to connect. The SPN is used in the process of mutual authentication between the client and the server hosting a particular service.

For DES-CBC-CRC cipher strength, make sure Use Kerberos DES encryption types for this account and make sure all options (except password never expires) are unchecked.ĭefine a Service Principal Name and Create a Keytab for the ServiceĪn SPN (Service Principal Name) is a unique name that identifies an instance of a service and is associated with the logon account under which the service instance runs.For RC4-HMAC-NT cipher strength, make sure all options (except password never expires) are unchecked.For AES256-SHA1 cipher strength, make sure This account supports AES 256 bit encryption is checked all others (except password never expires) are unchecked.For AES128-SHA1 cipher strength, make sure This account supports AES 128 bit encryption is checked all others (except password never expires) are unchecked.On the "Account" tab for user “negotiatestserver”,.Locate your newly created user in the Users tree in the left hand pane and double click it.Click Next.Ĭonfigure Your User to Comply with the Kerberos Protocol Verify that none of the password options are checked.Click Next, and enter a password (and of course, memorize it).Type in the user “negotiatetestserver” in the "Full Name" field and in the "Logon Name" field.Right click on the Usersnode and select New/User.Launch Programs/Administrative Tools/Active Directory Users and Computers tool.Create a User “negotiatetestserver” in Active Directory for Your Oracle WebLogic Server instanceįigure 2: Account tab showing properties for “negotiatetestserver” user on KDC The account type should be "User", not a "Computer" in the AD. In this case it’s part of OTHERDOM.DOM domain. In our example, the principal name will be The machine hosting Oracle WebLogic Server doesn't have to be part of domain. The principal name would be something like while the REALM.NAME is the administrative name of the realm. In this step, a Kerberos Principal representing Oracle WebLogic Server is created on the Active Directory. Create an Account for Oracle WebLogic Server Server

Oracle WebLogic Server's SPNEGO Token Handler code accepts and processes the token through GSS API, authenticates the user and responds with the requested URL.Ī Windows 2008 Server domain controller can serve as the Kerberos Key Distribution Center (KDC) server for Kerberos-based client and host systems.

The client re-sends the HTTP GET request + the Negotiate SPNEGO Token in an Authorization: Negotiate base64(token) header.

The TGS/KDC (MACHINEC) supplies the client with the necessary Kerberos Ticket (assuming the client is authorized) wrapped in a SPNEGO Token.

The client (Browser on MACHINEA) then requests the session ticket from the TGS/KDC (MACHINEC).

Oracle WebLogic Server (MACHINEB), running the SPNEGO Token Handler code, requires authentication and issues a 401 Access Denied, WWW-Authenticate: Negotiate response.

When the logged-on user (MACHINEA) requests a resource from Oracle WebLogic Server (MACHINEB), it sends the initial HTTP GET verb.

The following list of steps are a detailed breakdown of the cross-platform authentication design shown above. Note that although above configuration is used for this scenario, SPNEGO should work for older versions of browsers, Oracle WebLogic Server, JDK, and so on.įigure 1: Machine Configuration for SPNEGO/Kerberos scenario

KDC (MACHINEC) - Windows Server 2008 R2 Enterprise SP1.

Oracle WebLogic Server (MACHINEB) – Linux version 2.6.18-238.0.0.0.1.el5xen with Oracle WebLogic Server 12c (Oracle JDK 1.6) installed.

Browser Client (MACHINEA): Windows 7 Enterprise (IE 9.0/Firefox 7.0.1/Chrome 17 installed).

(Kerberos is responsible for authentication only authorization is still handled by Oracle WebLogic Server.)įollowing configuration is used to demonstrate this scenario: The server will then use the information for authentication and grant access to the resource if the authenticated user is authorized to access it. Oracle WebLogic Server will be able to recognize the ticket, and extract the information from it. Note that this feature also works for Java SE clients. The purpose of this feature is to enable a client browser to access a protected resource on Oracle WebLogic Server, and to transparently provide Oracle WebLogic Server with authentication information from the Kerberos database via a SPNEGO ticket.

This article describes how to enable Microsoft clients (browsers in this case), authenticated in a Windows domain, using Kerberos, to be transparently authenticated in a Oracle WebLogic Server (Oracle WebLogic Server) domain, based on the same credentials, and without the need to type in a password again.
