Return username in report instead of email address in Power BI Report Server

Hello,

I'm using the DAX function, username() in a Row-Level Security role.  In Power BI Desktop, this functions returns the username in this format: domain\user which is expected.  However, when I publish the report to Report Server, this function returns the user's email address.

 

How can I return the username in this format domain\user?

I've created a support ticket with Microsoft and they've informed me that this is an expected behavior. In that, the USERNAME() dax funtion returns UPN instead of domain\user format when report is published to Power BI Report Server.

Are you sure you are deploying to an on-prem report server?

 

As noted in the example here USERNAME - DAX Guide 

 

USERNAME() should return the name in domain\user format unless you are quering AzureAS or the Power BI Service in which case it returns the same value as USERPRINCIPALNAME() (which is an email address format)

Hi @d_gosbell , 

I'm sure I'm deploying to Report Server. See image below.  Also, authentication in through an on premise Active Directory.  Is there any setting in a config file on Report Server in which needs to be changed to make this work?

I'm not aware of any config setting that would change this. I've never seen this behaviour before.

 

This might be some AD configuration. When you look in the top right corner of the report portal what format is the username there? Is it domain\user or user@domain ?  You might need to open a support ticket with Microsoft to get help on this.

It displays the user's name. For example, John Doe.

What do you have using UserPrincipalName() ?

Hi @freginier ,

With UserPrincipalName() , I also get the email address which I believe is expected. However, I do not want to return the email address of a user but their username instead.  A user's username is going against my dataset. Email address is not.
