We have configured our Blackberry Mobile Device Service to allow Kerberos authentication so users can access secured internally developed ASP.NET intranet applications on their Blackberry browser. The username and password authentication does not seem to be working correctly.
When a user attempts to access a page in the application on his or her Blackberry, the authorization works correctly if the specific page has been accessed recently on that user’s desktop computer. However if the user has not recently navigated to that exact page on his or her desktop computer, Blackberry returns a HTTP Error 500: Internal Server Error with the text “Login failed for user ‘NT AUTHORITY\ANONYMOUS LOGON’“.
The issue exists on all Blackberry models.
The web application ASP.NET version is 2.0.50727
The web application server is Microsoft server 2003 with IIS 6.0
The backend database is SQL Server 2003 (9.0.4053)
The Blackberry Enterprise Server version is 5.0.3 with MR4
