Can't Login Into CRM with Basic Security Role???

So I wanted to create a security role with minimum access to assign to users.  I did this basically allowing only access to accounts that are created by the user.  When the user tries to login into CRM however they get an Access Denied error.... When I switched the security role to something like System Admin they can login.

Is there somewhere in the security role itself that controls just being able to log into CRM?  This is Dynamics 2016 online.
