ADSI and Reporting Services Permission issue.

I have a stored proc that calls on a view in sql server. The view is
actually my Active Directory LDAP query. I have already created a
linked server and account for my user name jkim.
I have a report that polls data from this stored proc. After I set the
datasource which uses an account "sqluser", I try to the run the report
and I get this:
An error has occurred during report processing. (rsProcessingAborted)
Get Online Help
Query execution failed for data set 'DispatchActivity'.
(rsErrorExecutingCommand) Get Online Help
OLE DB provider 'ADSDSOObject' reported an error. The provider
indicates that the user did not have the permission to perform the
operation.
The data source uses the account "sqluser" which is an account that's
stored in the report server. I'm pretty sure this is what's causing
the error. Does 'sqluser' have to be an actual Active Directory user
for it to have access to the ADSDSOObject?
I don't know if I'm making any sense.nevermind, i figured it out.
i didn't check the "use as windows authentication" checkbox in the
datasource.
