I used the custom forms authentication sample from Codeplex / MSDN to use as a starting point. One quick (dumb?) question is, the machine running SSRS is 64-bit. Do I need to compile the forms authentication DLL as 64bit? Thanks, Chris

anyone?

Hi Chris, Generally, compiling for "Any CPU" is fine. Since you are using Reporting Services 2008 R2, you can also compile the assembly for x64 platform.
