I have an actually pretty simple task but I am having a really hard time to achieve it:
We have a library providing basically all membership- and profile-related data and action and exposing those via defined interfaces and models.
For example there's a GetUser(id) method, a Login(username, password) method, ResetPassword etc. etc.
So technically all I would need to do is just to write a wrapper to be used by sitefinity which will proxy the authentication and profile related calls to the library.
Unfortunately, this "just" is getting bigger and bigger the more I try to figure out the "right" way. First I've tried to implement a custom MembershipDataProvider (like here: https://www.progress.com/documentation/sitefinity-cms/custom-membership-provider-full-code), but when it came to GetUsers() I had to let it go, because although there IS the possibility to create a IQueryable, I cannot Select the Model.User objects from my entities bcs the UserName property is read-only and calling the setUserName method in the initializer will cause an enumeration of the IQueryable. Btw we have about 150k of users in the database so working on a List instead of IQueryable is not an option.
Afterwards I did a lot of retries but with minor success... Any Ideas how I could achieve what I need? the Requirements are pretty simple:
Please help :)
