Hey there everyone, Well I have the OpenNebula installed on a vm with in my infrastructure but I am having issues adding my hosts to the frontend. I have chacked the ~/.one/one\_auth file on the frontend and the intended node and the passwords are the same however I changed my password in the GUI after I first got logged on This is the error I get at the cli trying to add one of my hosts **onehost create farragut -i kvm -v kvm -n dummy** **[HostAllocate] User couldn’t be authenticated, aborting call.** Just not sure what is causing this, and before you ask yes I have googled it several times and got things that really didn’t make sense to me. ---

Hi, If you change your password, you need to update the one\_auth file with the new one. That is where you set your username and password for the CLI commands. You can read more here: [http://docs.opennebula.org/4.12/administration/users\_and\_groups/manage\_users.html#user-authentication](http://docs.opennebula.org/4.12/administration/users_and_groups/manage_users.html#user-authentication) ---

Thank you sir i will give that a shot I appreciate your help, I would imagine they have to be changed in the frontend as well as all nodes correct? ---

> [@Nexusguy59](#): > > I will keep researching but this is very annoying. Yes, authentication can be annoying, but it’s there for a reason… My guess is that the VirtualMachinePoolInfo calls are failing because the scheduler was launched before the oneadmin password was changed in one\_auth. Try restarting the opennebula service. ---

Hello Carlos, ``` Thanks again, It appears that this is still an issue after ``` restarting OpenNebula Service and rebooting the host box to have a clean slate. I will have to keep researching, I am a noob so I am still learning how to diagnose and work in the OpenNebula environment. By the way I am going to try to install it on CentOS as the frontend and see if that works any better. Right now I am an all Ubuntu 14.04 and 15.04 Shop so-to-speak. Thank you very much for your help, Michael A Cooper Linux/Windows Web Administrator ---
