Bypassing SSO property on oVirt 4.0

  • 772

I have upgraded oVirt engine from 3.6 to 4.0, after the upgrade i could not access the webadmin portal, the welcome page displays this message:

The client is not authorized to request an authorization. It's required to access the system using FQDN.

After reading on oVirt 4.04 Release Notes i learned this was due to Single Sign-On using OAUTH2 protocol, ovirt requires me to access the engine with FQDN, unfortunately I'm managing my resources remotely with just one public IP and i don't own any domain name. how do i get around this issue?. If it can be of any help, below is my oVirt engine setup summary

  1. You can specify an alternative FQDN simply by editing the SSO_ALTERNATE_ENGINE_FQDNS variable in /etc/ovirt-engine/engine.conf.d/11-setup-sso.conf on the oVirt Engine.

    Then restart the engine daemon:

    # systemctl restart ovirt-engine.service

    If you have no control over DNS you can improvise using local /etc/hosts files. A dirty-ish hack but should be effective enough to get things working
