Map user names for Analysis Services data sources

Hi Anonymous ,

Thanks for your replies, I do not understand much how to use wildcard, as the link you shared also not really mention in detail about this. However, my problem is from the platform of MS, there is error somehow with blank pace and the buttons in mapping users do not work at all to me. There is no pace/raw for me to add new user, as usually there is a blank box raw, where I can add email and ID of users, then clicking add new rules, then save. But now that blank box raw is disappeared and the button "add new rules" didn't work also. 

I tried on many web browser from MS Edge, Firefox, Chrome.... but it doesn't work, I cannot add even only 1 user. Could you please help me in this case?

Thanks,

Thu
