On Ubuntu Guests root access is configured via sudoers. This should not be changed because of security reasons.
Webmin and ssh outside of Cloudmin work as expected. In Cloudmin no ssh login is possible: Message: ssh login failed, user does not have root access.
Just to use the features ssh and login, it would be great to allow ssh login without root privilege.
At the moment webmin acces is granted at webmin -> webmin-servers, but not in the cloudmin module.
