Err 501 - Login

In a database using the following URL:

http://dev1/names.nsf?login&redirectto=%2Fapps%2Fopenntf%2Fxsnippets.nsf%2Fhome.xsp http://dev1/names.nsf?login&redirectto=%2Fapps%2Fopenntf%2Fxsnippets.nsf%2Fhome.xsp

I get the following message:

Error 501

HTTP Web Server: Function Not Implemented Exception

What should I set on the server to allow login redirection?

Subject: HTTP Error

Check to ensure that the function you are trying ot perform is supported by your JVM. This could be the issue.
