I have developed a variety of Custom ASP.NET managed security providers, for Membership, Profile, and Roles, automatically handling a variety of federated identity management scenarios. I would like to leverage these in DNN. THis leads to two questions:

1) Is there a DNN configuation that can use all of these? I am familiar with using the standard SQL membership provider from DNN, but how about Role and Profile?

2) Some of my DNN pages take advantage of ASMX-based Web Services using AJAX based on the same server. Has anyone set up DNN and ASP.NET in a server farm to share cookies, so the same identity can apply to both the DNN pages ans the Web Services they call...

Thanks in advance
