I just setup Virtualmin GPL on a new dedicated server for some friends of mine. They have not touched the configuration of it, however after 2 days for some reason Virtualmin/Webmin will not take the login credentials of a virtual server account I created on there. I have changed the password multiple times for this account, but the login screen keeps rejecting it with the following logged in /var/log/secure:
Jan 24 21:37:39 storman webmin: Invalid login as [hidden] from 126.96.36.199 Jan 24 21:37:45 storman webmin: Invalid login as [hidden] from 188.8.131.52
Now here's the strange thing, I can login with this exact username / password over FTP! This is the main administrative username for this account that it will not take. In addition, I can also add "Extra Admins" to this virtual server and it will allow this person to login without an issue as well.
