I am struggling with getting my SP to update a table, grab the Identity of the new row and then creating a new folder by that name.  I have the SP written and tested...works PERFECTLY...as long as I run it as the SA or other sysadmin account.  I need my DNN users to be able to do so.

This is SQL 2008 and I have researched and try about every combination of  "execute as", proxy users, and even tried making my DNN account an SA equivalent...none of which worked.  I keep getting permission denied.  

Can someone point me to a solution OR an alternative method of creating this folder?

Pulling of hair, grinding of teeth, etc. etc.

Is the database local to DNN or external? Is the error from the SP execution or the folder creation on the file sys?

Sites are on the same server as SQL.  

Error is from attempt at the end of the proc:

/* Standard insert code for proc is here...it works fine - 

here is where we have a problem */

SET @RecordID = CONVERT(varchar(10),SCOPE_IDENTITY())

SET @FilePath = 'C:\Site1\Portals\0\Events\'

execute as login = 'domain\username'

/* Read in the folders in the */

INSERT INTO @DirTree(subdirectory, depth)

EXEC master.sys.xp_dirtree @FilePath

IF NOT EXISTS (SELECT 1 FROM @DirTree WHERE subdirectory = @RecordID)

SET @FilePath = 'C:\Site1\Portals\0\Events\' + @RecordID

EXEC master.dbo.xp_create_subdir @FilePath

REVERT

We get the following error from our site call:

Cannot execute as the server principal because the principal "domain\username" does not exist, this type of principal cannot be impersonated, or you do not have permission.

We have confirmed that we have the logins and users properly set up (as best we can tell)....and the proc runs fine when logged in as sysadmin role...we are just trying to get a folder created under Portals/0/events when someone adds a row to a table in the database

Most likely you are struggling with file system permissions.

I wouldn't create a folder in SQL, this should be done in your code behind.

It isn't a file system permission issue (for sure...using local windows admin account, domain admin account, and any other account I thought might work including service acct for SQL).

It has to do with some limitation in SQL 2008 that doesn't permit impersonation of a sysadmin account which is required to run xp_cmdshell....which yes I know is not the most secure process but that is what is available.

I am not writing code for this...been several years since I did any coding (I Buy Spy - DNN 5 days)...it would be a major waste of time for me to try to get back up to speed  and start coding again.  Not going to happen....ever again!

Just looking for a way to create a folder when I add a row to the table... just using a stored proc (limit to my coding!).

Thanks for the response though!
