SYMPTOMS
Consider the following scenario. You try to visit a Web site that uses RSA SecurID authentication. A Web publishing rule in Microsoft Internet Security and Acceleration (ISA) Server 2004 publishes the Web site that you try to visit. You have enabled Web access authentication cookies for the domain. In this scenario, ISA Server prompts you for your credentials. Additionally, the Web server also prompts you for your credentials.

Note ISA Server must validate your credentials and then pass the validation to the upstream Web server. The Web server itself must not prompt you for your credentials. When you enable domain cookies, ISA Server must prompt you for your credentials one time.



CAUSE
This problem occurs because RSA SecurID authentication and validation fails for single sign on (SSO) from ISA Server to the upstream Web server that uses RSA Authentication Agent 5.3.



RESOLUTION
To resolve this problem, apply the fix that is described in the RSA SecurCare Online Knowledgebase article, ID16753. For more information about this fix, visit the following RSA SecurCare Online Web site:
