Report Builder with Forms Authentication

Hi,

After implementing custom security extension for forms authentication, the report server works fine with Report Manager and web application. However, there is a problem with Report Builder.

It gives SecurityException "That assembly does not allow partially trusted callers.". Its becos I am using my own security assembly for authentication. I resolved this issue by using the following in my assemblyinfo.cs

[assembly: System.Security.Permissions.PermissionSet(System.Security.Permissions.SecurityAction.RequestMinimum, Name="FullTrust")]

However, now when I login to Report Builder it gives me error System.IO.FileNotFoundException. Its not able to find my security assembly.

I also tried giving FullTrust to the assembly using Framework 2.0 Configuration. I read somewhere that the ClickOnce application caches its last called settings in the manifest file and you have to delete the manifest and manually alter the security in the application settings(properties).

Is this true? Is there any solution to this issue? Is this really an issue with clickonce application?

This is really urgent. Any suggestions.

Thanks in advance.

Is there any solution to this?
This is really frustrating. We are duplicating all our security code into CustomSecurity Extension module. At least it stopped giving error at the point, where the call was made to an assembly. Dont know if it will really work, even after moving all the code to extension module.

I just hope someone from MS at least reads this post, if not care to reply.
I hope this helps someone.

Thankssql
