SpnegoTAICommands group (deprecated)

Use the Jython or Jacl scripting languages to configure security with wsadmin.sh. The commands and parameters in the SpnegoTAICommands group can be used to create and manage configurations that are used by the Simple and Protected GSS-API Negotiation Mechanism (SPNEGO) trust association interceptor (TAI).

Deprecated feature:

In WAS v6.1, a trust association interceptor (TAI) that uses the Simple and Protected GSS-API Negotiation Mechanism (SPNEGO) to securely negotiate and authenticate HTTP requests for secured resources was introduced. This function was deprecated in WAS Version 7.0. SPNEGO web authentication has taken its place to provide dynamic reload of the SPNEGO filters and to enable fallback to the application login method. depfeat

The SpnegoTAICommands command group includes the following commands:



addSpnegoTAIProperties

The addSpnegoTAIProperties command adds properties in the configuration of the Simple and Protected GSS-API Negotiation Mechanism (SPNEGO) trust association interceptor (TAI) for the application server.

Target object None

Parameters and return values

-spnId

This is the SPN identifier for the group of custom properties that are to be defined with this command. If not specified, an unused SPN identifier is assigned. (String, optional)

-host

Host name portion in the SPN used by the SPNEGO TAI to establish a Kerberos secure context. (String, required)

-filter

Defines the filtering criteria used by the class specified with the above attribute. If no filter is specified, all HTTP requests are subject to SPNEGO authentication. (String, optional)

-filterClass

Name of the Java class used by the SPNEGO TAI to select which HTTP requests will be subject to SPNEGO authentication. If no filter class is specified, the default filter class, com.ibm.ws.security.spnego.HTTPHeaderFilter, is used. (String, optional)

-noSpnegoPage

Specifies the URL of a resource that contains the content the SPNEGO TAI will include in the HTTP response to be displayed by the (browser) client application if it does not support SPNEGO authentication. (String, optional).

If you do not specify the noSpnegoPage attribute then the default is used: 

"
<html>
<head>
<title>SPNEGO authentication is not supported.
</title>
</head>" +
"
<body>SPNEGO authentication is not supported on this client.
</body>
</html>";

-ntlmTokenPage

Specifies the URL of a resource that contains the content the SPNEGO TAI will include in the HTTP response to be displayed by the (browser) client application when the SPNEGO token received by the interceptor after the challenge-response handshake contains a NT LAN manager (NTLM) token instead of the expected SPNEGO token. (String, optional).

If you do not specify the ntlmTokenPage attribute then the default is used: 

"
<html>
<head>
<title>An NTLM Token was received.
</title>
</head>" + "
<body>Your browser configuration
is correct, but we have not logged into a supported Windows Domain." + "
<p>Please login to the application
using the normal login page.
</html>";

-trimUserName

Whether (true) or not (false) the SPNEGO TAI is to remove the suffix of the principal user name, starting from the @ that precedes the Kerberos realm name. If this attribute is set to true, the suffix of the principal user name is removed. If this attribute is set to false, the suffix of the principal name is retained. The default value used is true. (String, optional)
