  CMS 12 Salesforce: Excessive failed login attempts.

  Allow user to accept or deny mai_trk_* cookies

In accordance with GDPR regulations, you can choose whether you want to accept cookies for Marketing Automation connectors. (Normally, the cookie is created when you submit a marketing automation form.)

Customers are responsible for presenting the cookie option dialog box to the user, obtaining the response, and then passing the response to Optimizely through the IPersonalizationEvaluator.AcceptCookies property. If the user chooses not to accept the cookies, some or all functionality of the connector will not work; the form will post successfully but personalization features will not.
