The documentation at http://opennebula.org/documentation:rel2.2:plan advises the reader to use the useradd command as follows:

useradd -d /srv/cloud/one -g cloud -m oneadmin

This, by default creates a user account that is disabled, i.e. a "!" entry exists in the password field of /etc/shadow.

The documentation does not advise the reader/user how to activate the oneadmin account or to create a password (activates the account), thus a reader/user following the steps as described will end up setting up a cloud system that cannot work.

The reader/user should be advised to setup a password for the oneadmin account, even if no interactive login to this account is necessary to administer the cloud. The password can be a random password generated by makepasswd.
