In this step, a Kerberos Principal representing Oracle Web Logic Server is created on the Active Directory. In our example, the principal name will be [email protected] The machine hosting Oracle Web Logic Server doesn't have to be part of domain. An 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. In the Proxy Settings dialog box, ensure that all desired domain names are entered in the Exceptions field. The principal name would be something like [email protected] The SPN is used in the process of mutual authentication between the client and the server hosting a particular service. The client finds a computer account based on the SPN of the service to which it is trying to connect. Verify that the proxy server address and port number are correct. The ktpass command-line tool enables an administrator to configure a non-Windows Server Kerberos service as a security principal in the Windows Server Active Directory. This identity assertion provider decodes Simple and Protected Negotiate (SPNEGO) tokens to obtain Kerberos tokens, validates the Kerberos tokens, and maps Kerberos tokens to Web Logic users. You need to configure a Negotiate Identity Assertion provider in your Web Logic security realm in order to enable SSO with Microsoft clients. klist—Lists your and both current and expired HSI tickets.kpasswd—Allows you to change your Kerberos password.

COM -Djava.security.krb5.kdc=MACHINEC -Djava.login.config= krb5-Djavax.use Subject Creds Only=false Web Logic Server includes a security provider, the Negotiate Identity Assertion provider, to support single sign-on (SSO) with Microsoft clients.

You can always do a klist both to see your tickets and locate your credentials cache.

For this example, we will authenticate, getting a ticket granting ticket, and list this out.

The system will request your current password before allowing you to enter and confirm a new password. Defaults, output, and some syntax can differ between Kerberos clients, so refer to the man pages on the machine you are using to confirm the details. For these examples, assume a user "someuser" with uid (scientist number) 1234.

Log in to a target client machine on which you wish to use HSI.
