PowerBI Service connection -> Kerberos encryption types

Hello

I set the connection between PowerBI Service and my on-premise SQL Analysis Services using Gateway. Everything working fine, I can refresh data set etc.

But security policies has changed and algorithm RC4_HMAC_MD5 from "Network security: Configure encryption types allowed for Kerberos" policy implemented on SQL Server was switched off. I tested it and looks like without RC4_HMAC_MD5 I can't set proper connection.

My question is, if there is any workaround to set proper connection without RC4_HMAC_MD5 algorithm turned on, for example using AES128/AES256?

Regards

Hi @Anonymous 

I think your problem is that RC4 encryption is off and you need to configure a new encryption type to refresh your dataset in Power BI Service.

You may refer to this Method :Method 1: Configure the trust to support AES128 and AES 256 encryption in addition to RC4 encryption

This method adds the newer encryption types to the trust configuration, and does not require any changes to the client or the service. 

Or you can refer to this Method:Method 3: Configure the trust to support AES128 and AES 256 encryption instead of RC4 encryption

This method resembles method 1 in that you configure the trust attributes.
