Function not implemented

I tried to authenticate the server with user name and password with the below url, there was error prompted in the server console.

http://servername/names.nsf?login&Username=Shibu%20Mathew&Password=welcome2lotus

HTTP Web Server: Function Not Implemented Exception

Please help me to fix this issue

Solution

You probably get this error because the server has been set up to use basic authentication (and not session-based authentication).

Try using http://<username>:<password>@servername/ instead.
