Northern Trail Outfitters (NTO) has deployed my domain.

To make sure that all of the Salesforce users log in using the branded login URL after deploying my domain, and give them a grace period for updating their bookmarks, the administrator should set the Redirect policy to Redirect with a warning to the same page within the domain. This will redirect users who try to log in from https://login.salesforce.com or another domain to https://nto.my.salesfo rce.com, and show them a warning message that they need to update their bookmarks. Setting the Login policy or preventing login from https://login.salesforce.com will not redirect users or give them a warning. Filtering with Form Factor will not affect log in URL.
