Symfony\Component\Security\Core\Authorization\AccessDecisionManager::decideConsensus
Grants access if there is consensus of granted against denied responses.
Consensus means majority-rule (ignoring abstains) rather than unanimous agreement (ignoring abstains). If you require unanimity, see UnanimousBased. If there were an equal number of grant and deny votes, the decision will be based on the allowIfEqualGrantedDeniedDecisions property value (defaults to true). If all voters abstained from voting, the decision will be based on the allowIfAllAbstainDecisions property value (defaults to false).
