I installed my gerrit on Ubuntu server.
As gerrit said:The first people who logined gerrit is Administrator.
So I logined first with openID (google account),and I am the Administrator indeed.
But,when next day I relogin gerrit with my google account, I become a new register. The id is 100001(Administrator 's id is 100000),but both email are google's email,and are same.
What happened?
The easiest way is to temporarily disable authenticated logins.
Edit your [auth] statement in gerrit.config to look like this:
[auth]
type = development_become_any_account
And then force login as the admin, grant yourself access and then restore the [auth] config.
Keep in mind that anyone with access to your server during this time will also be able to be any account, so setup a firewall or something to narrow access down to just your workstation while you complete the above steps.
