We are planning to implement security extentions.

The sample solution is working fine for reporting services enterprise edition, but this is not working for standard edition as security extentions are not supported by standard edition.

Is there any way to implement security extentions for standard edition achieving single sign on with a .NET application ?

Any suggestions, tips, tricks, pitfalls?

Custom security is supported all the way down to Workgroup edition with SSRS 2005.|||

Thanks, for the update.

I have not given much details, I want to achive custom security extentions working for standard edition of reporting services using SQL Server 2000 with service Pack 3.

Please do let me your suggestions.
