I'm trying to get windows accounts into commerce so that I can connect a contact to a windows login.

I've set up MultiplexingRoleProvider like this:

<add name="MultiplexingRoleProvider" type="EPiServer.Security.MultiplexingRoleProvider, EPiServer" provider1="WindowsRoleProvider" provider2="CMSRoleProvider" providerMap1="WindowsMembership1Provider" providerMap2="CMSMembershipProvider" />

I've set up MultiplexingMembershipProvider like this:

<add name="MultiplexingMembershipProvider" type="EPiServer.Security.MultiplexingMembershipProvider, EPiServer" provider1="WindowsMembershipProvider" provider2="CMSMembershipProvider" />

Now I can't seem to get a windows account into neither cms nor commerce. Now I've tried to set up a page so that only authenticated users can access it. With a new browser window, I get the login screen.

I can't login with my windows account there.

When logging in now with my default admin login I get an error message stating that commerce tried to delete the windows account. That doesn't make sense.

[Exception: The method or operation is not implemented.]
   EPiServer.Security.WindowsMembershipProvider.DeleteUser(String username, Boolean deleteAllRelatedData) +60
   System.Web.Security.Membership.DeleteUser(String username) +171
   EPiServer.Business.Commerce.HttpModules.ProfileModule.Profile_MigrateAnonymous(Object sender, ProfileMigrateEventArgs pe) +1762
   System.Web.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +80
   System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +270

Q: How do I connect a windows account to a commerce contact?

Q: What is the profile module undertaking with Migrate_Anonymous, trying to delete the user, when logging in as administrator?
