Installed Webmin version 1.540 (http://sourceforge.net/projects/webadmin/). Opened web browser from another machine on local network and connected to webmin server on port 10000. Entered my ubuntu user name and password. Received this from Webmin server: Login failed. Please try again. This happens every time with known good user name and password until it blocks the connecting IP address for multiple failed attempts. Tested with the previous version of Webmin and have same problem. I forced a downgrade of sudo package from 1.7.4p4-5ubuntu5 to 1.7.2p7-1ubuntu2.1 and thereafter login to Webmin server was successful.
