Tomcat 7 digest authentication issues

[Gomes Queries]

Hi,

I wanted to test my application with enabling digest authentication in Tomcat 7 server. I did required changes for enabling digest authentication in server.xml and web.xml files.
Now if i send request with digest authentication credentials in challenge response, the digest authentication is not successful. Server is sending Challenge request again... Is there any issue with the digest authentication in tomcat 7?
If anyone can point me in the right direction, I would be most grateful.
