Question

I have followed this tutorial and setup everything to get ready to go with FBA.

Any solutions to resolve this problem?

When I gone through this Test Lab Guide the requirement says to use Windows Server 2008 R2 Enterprise With SP1 but i have installed Windows Server 2008 R2 Standard with SP1, does that makes any difference?

Answer 1

I don't know if it is the exact solution but it worked for me.

Here's what i did, I installed SQL Server 2012 Enterprise SP1 + SP2 instead of Express and Forms Based Authentication started working like a charm.

Thanks for your help guys.
