I have successfully installed gerrit on local centos machine with help of http://dcycleproject.org/blog/82/setting-gerrit-centos-evaluation

I explored below links but did not find any relative information: Migrating from OpenID 2.0 to OpenID Connect OAuthWebSecurity Migrating from OpenID 2.0 to OpenID Connect
