SSAS Remote connectivity issue

Hi ,

I installed SQL 2017 Deloper edition in my server. Installed with ABCDomian\Administrator.
I am able to connect SSAS with windows credentials.

Requirement is one user wants to connect SSAS remotely from his SQL management studio..He signin his PC with ABCDomain\xyz username. using his windows authentication not able to connect ssis.

I noticed there is no sql server authentication to connect ssas. Only windows credentails we can connect ssas? If some user from same domain wants to connect remotely then how?

How to conenct ssas using his account ABCDomain\xyz? Please help.

Thanks,
Jo
