I reinstalled the system with the Identity Manager. In the previous installation the Extensions debugging used to work, when I attach to the mmsscript.exe process. With the new installation I attach the debugger to the same process but the execution doesn't stop on the breakpoint. I know that the Extension is applied to the account, because the account gets created according to the rules in the extension.One difference I noticed with this installation of Visual Studio, I do not have 'Attach to process...' choice in the debug menu, I have it only in the Tools menu. May be it matters, which account I am using to run Visual Studio? What am I missing?

Are you using Visual Studio Express? That version does not have the ability to attach to a process.Mark

I double-checked the in the Help>About. It is Professional Edition, Version 9.0.30729.1 SP

hi, some hints:do you you want to debug an extension of the Sycnronization Engine? I usually attach the miisserver.exe process instead of the mmsscript.exe.Do you get specific errors, when attaching the process, (eg. Symbols have been loaded)?Have you checked these posts:http://social.technet.microsoft.com/Forums/en-US/identitylifecyclemanager/thread/51f55fd6-bed7-412d-b410-d0ad4113f533/http://social.technet.microsoft.com/Forums/en-US/identitylifecyclemanager/thread/90590062-4676-45ae-8de9-31997d22d332http://social.technet.microsoft.com/Forums/en-US/identitylifecyclemanager/thread/896e4676-b604-4780-b59e-005313fd5167/Hope this helps/Matthias

Here is one thing you can try: Open your Project in Visual Studio Select <project name> Properties from the Project menu To open Advanced Compiler Options dialog click Advanced Compiler Options From the Generate debug info list, select Full. Go to the extensions folder and delete all files for this project.Recompile the project.Attach the debugger to the miisserver.exe process.Markus Vilcinskas, Technical Content Developer, Microsoft Corporation

Hello Markus,Thank you so much for your reply!!! Changing "Generate debug info" toFull and removing the extension project's files worked.The only difference I still have to attach to mmsscript.exe, miisserver.exe doesn't work.
