When I attempt to login to Virtualmin with a user that is not root, then I always get the login failed error with the correct password. I have changed the password and it still doesn’t work, how do I fix this?
P.S. I just created a test user, he can’t loging to port 10000, I say the only user allowed is root or Administration username as displayed in Virtual Server Summary
Virtualmin/Webmin is an administrative tool. Regular users (usually managed in the Mail and FTP Users page in Virtualmin, found by clicking “Edit Users”) can use Usermin for reading mail, resetting passwords, and optionally a bunch of other stuff. Only the domain owner user can perform administrative tasks, though you can create other users with some administrative capabilities. (And some permissions can be granted to regular users, like editing databases. But that can be a little trickier.)
If you expect a virtual server owner to login to Webmin/Virtualmin (i.e. port 10000) then you should make sure that Webmin login enabled feature is turned on at virtual-server.name - Edit Virtual Server page.
