Hey People,
this probably needs to be in a SharePoint forum, but there aren't any "MS supported" SharePoint forums, so I'll start here and see how I go.
I recently set up an SSRS2008R2 instance on an existing SP2007 server, in SP integrated mode and used the SSRS2008 (not R2) add-in for SharePoint to hook it up.
It looks like I've got all the Kerberos hooked up correctly and I can get the logged in SP user to pass all the way through into my SQL2008R2 Datawarehouse DB and my SSAS2008R2 cubes. (Yes I'm using Windows Integrated/Kerberos all the way through)
However I'm finding that if a second user accesses the reports (same dataconnection and datasets, but potentially different report) within a couple of minutes of the first user, the second user connects to the DB/Cubes as the first user.
I've enabled HTTP logging for SSRS and can see that when SP hands the request over (SSRS and SP are on the same machine. SQL and SSAS are on a separate server) to SSRS, it's connecting as the first user.
It seems like SP (the SSRS2008 add-in/compoents?) is caching the credentials passed to SSRS.
Has anyone else seen this?
Let me know if there's more detail I can provide.
Thanks
Craig
