Map user names for Analysis Services data sources and change login to Data Source is gone

[kdmishra]

Previously I could go into manage gateware, go to the Gateway cluseter, choose the data source, and then add/edit the credentials that accessed the data source. Furthermore, for tabular data sources, I could map user names. This is completely gone today. This was my one way around a data source issue we were receiving. 

This is what I used to have to manage my gateway and data source:

https://docs.microsoft.com/en-us/power-bi/connect-data/service-gateway-enterprise-manage-ssas

Now I have something that looks like this with no way to manage my data source or add user mapping.

I can only do user mapping or change data source login credentials if I add a new data source. But only when I do an add. I can never go back and edit. 

Where is this hidden now? This was our main way of correcting "can't connect to data source" issues.

I ran into the same issue this morning, and your suggestion of turning off Tenant Administration works as far as exposing the data sources. But the problem still remains with editing user mappings on existing data sources. Adding a new rule does not light up the Save button. In fact nothing I do to an existing data source lights up the Save button. This is a huge problem. Because of the way our email addresses and AD user names are, we have to map users quite often. We also have a lot of data sources. Microsoft needs to fix this right now!!

Here we have the same problem with editing user mappings on existing data sources. Changes do not light up the Save button. We have found that we can save changes again if we delete a great part of the user mappings, it seems now to be limited to 64 mappings. And we had a lot more working previously! Microsoft needs to fix this right now!

I just figured it out. 

In my first image on the right, there is a button called "Tenant Administration". If I turn it off, then I have access to the data sources. 

They made this change today (at least in our account) but none of the documentation reflects it yet. Ugh.
