Kinit no credentials cache file found validating tgt
If your client machine uses role principals for HSI transfers, you do not need to worry about executing Kerberos commands yourself; you just invoke hsi without further ado.
Contact your division sysadmin/CSAC representative to find out if your machine is equipped with this infrastructure, or if there is one you should use that is so equipped.
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 Web Logic Server (Oracle Web Logic Server) domain, based on the same credentials, and without the need to type in a password again.
The purpose of this feature is to enable a client browser to access a protected resource on Oracle Web Logic Server, and to transparently provide Oracle Web Logic Server with authentication information from the Kerberos database via a SPNEGO ticket.
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.
Here’s the servlet code used in our case (Simple Test Servlet.java): import javax.servlet. The server will then use the information for authentication and grant access to the resource if the authenticated user is authorized to access it. In order for cross-platform authentication to work, Oracle Web Logic Server can be used to parse SPNEGO tokens in order to extract Kerberos tokens which are then used for authentication thus providing transparent authentication to the end user.(Kerberos is responsible for authentication only; authorization is still handled by Oracle Web Logic Server.) Following configuration is used to demonstrate this scenario: Note that although above configuration is used for this scenario, SPNEGO should work for older versions of browsers, Oracle Web Logic Server, JDK, and so on.

If Oracle Web Logic Server is using Oracle JDK, specify following options in the Oracle Web Logic Server java command line: -Dsun.security.krb5.debug=true -Djava.security.krb5.realm=SECURITYQA.
