have a question regarding the PBI in SSRS tech preview. We have a custom authentication provider rather than the standard AD provider that SSRS 2016 ships with. All works as expected in SSRS except that AD accounts are not used to log in. Report builder allows you to provide a dialog than then authenticates with the provider in SSRS. When saving a PBIX file to SSRS from PBI desktop, you are not prompted for credentials and I assume that it just takes some token based on the identity of the user running PBI desktop. Basically, you are not able to save to SSRS. This is something that should be fixed, and I assume the issue is on both the SSRS server side and also on the PBI client. The reason I say this is because when I change the auth provider to standard out of the box for SSRS 2016 (AD) the file saves, but when I set SSRS back to custom auth I am not able to run the PBI report in SSRS site. This is a showstopper for us since we have to use a custom auth provider in SSRS. I was told during the PBI Premium webinar this is supposed to be supported, any input as whether this is yet fixed?
thank you
