SYMPTOMS

When you use SecurID authentication to request a Web page that is published by a Web publishing rule in Microsoft ISA Server 2000, you are not redirected to the requested URL after you enter the correct credentials on the SecurID logon page. Instead, ISA Server responds with the SecurID logon page and prompts you to enter your SecurID credentials again.

This problem occurs if all the following conditions are true:
  • You have installed ISA Server Feature Pack 1 and SecurID authentication on your system, and you have enabled the SecurID authentication Webfilter.
  • You have two Web publishing rules. The initial Web page request is served by the first Web publishing rule. This rule has no SecurID authentication enabled. The page that is published by the first Web publishing rule links to another URL that is published by the second Web publishing rule. The second Web publishing rule has SecurID authentication enabled.
  • The second Web publishing rule processes the redirection. The second rule applies the same host name as the first Web publishing rule.

For more information about how to install ISA Server Feature Pack 1 and configure SecurID authentication, visit the following Microsoft Web site:

For more information about how to setup SecurID authentication in ISA Server 2000, visit the following Microsoft Web site:
http://www.microsoft.com/downloads/details.aspx?FamilyID=2f92b02c-ac49-44df-af6c-5be084b345f9&DisplayLang=en.
The problem does not occur if the initial request is immediately processed by the second Web publishing rule. For example, if the client first requests http://www.example.com, the page that is published by the first Web publishing rule redirects to http://www.example.com/securefolder/default.html. The second Web publishing rule processes this request, and the request is denied. If the client first requests http://www.example.com/securefolder/default.html, this problem does not occur.

CAUSE

This is a problem in the SecurID filter in ISA Server 2000. This filter does not send the correct redirection URL in response to a successful SecurID logon.

MORE INFORMATION


ISA Server 2000 implements RSA authentication as follows:
  1. If a client requests a Web site that is published by ISA Server, and SecurID is enabled on the Web publishing rule, the SecurID Web filter first responds with the SecurID logon page.
  2. After the client has successfully entered the SecurID credentials and submitted the page, the SecurID Web filter redirects to the page that was originally requested.


To enable or to disable the SecurID authentication Webfilter, follow these steps:
  1. In the ISA Microsoft Management Console (MMC), expand Servers and Arrays and the server name node.
  2. Expand Extensions, and then click Web Filters.
  3. Right-Click the Web Filter for RSA SecurID Webfilter.
  4. Click enable or disable.

To set SecurID authentication for your Web publishing rule, follow these steps:
  1. In the ISA MMC, expand Servers and Arrays and the server name node.
  2. Expand Access Policy, and then click Web Publishing Rules.
  3. Create a new Web Publishing Rule, or select an existing rule that you want to configure. Right-click the rule, and then click Properties.
  4. Click the RSA SecurID tab, and then click to select or to clear the Enable RSA Web Authentication Feature Set for this rule check box.


To troubleshoot this problem, use Microsoft Network Monitor to analyze the HTTP traffic. After the client submits the SecurID credentials, the HTTP response from the ISA Server may include a response that is similar to the following:
HTTP: Response to Client; HTTP/1.1; Status Code = 200 - OK
	HTTP: Protocol Version =HTTP/1.1
	HTTP: Status Code = OK
	HTTP: Reason =OK
	HTTP: Connection =close
	HTTP: Content-Length =733
	HTTP: Refresh = 1; URL=
Because the URL= field is empty, the client is not redirected to the original URL. After you install this hotfix, the response will look similar to the following:
HTTP: Response to Client; HTTP/1.1; Status Code = 200 - OK
	HTTP: Protocol Version =HTTP/1.1
	HTTP: Status Code = OK
	HTTP: Reason =OK
	HTTP: Connection =close
	HTTP: Content-Length =733
	HTTP: Refresh = 1; URL=/securefolder/default.html
