|Issue||Protocol Transition fails and the user gets a 401 unauthorized message|
Protocol Transition does not work. User receives a 401 message in the browser.

2009-05-27 15:53:36 -0400 -  - <Debug> - AUTH_TYPE: Basic
The following messages do NOT appear in the ct_agent.log file. The absence fo the "WildCard map extension loaded" suggests a problem with the wildcard map.
2008-04-29 13:46:25 -0700 -  - <Debug> - Windows user token cache initialized, size : 3000, ttl:28800
The ct_tokengen.log shows startup information but there is no other messages in the log files.
|Cause||This may occur if the anonymous user account defined for the IIS application pool is not able to access content on the local server. By default the IIS server access content under the permission of the IUSER account. Since no content is served on the server the wildcard map is not called.|
|Resolution||If the IIS anonymous user account has been changed ensure that the account credentials are valid and that the user has sufficient privileges to serve anonymous content from the web server. If the account is a domain account ensure that this user is able to do a domain authentication. Right click on the "default web site" in the IIS manager and select the "Directory Security" tab. Click the "Edit" button under "Authentication and Access Control" and click "Enable Anonymous Access" and select the IUSER account.|
