Hello,
I have installed Phabricator on ubuntu 14.04.But when I enter phabricator.domain.com,it shows an authentication error "Authentication Failure
This Phabricator install is not configured with any enabled authentication providers which can be used to log in. If you have accidentally locked yourself out by disabling all providers, you can use phabricator/bin/auth recover <username> to recover access to an administrative account."
