Dear Experts,

I have scenario where I have two users with same name but in different domains "domain1\user1" & "domain2\user1". Both have user profiles present in User Profiles

I have list where I am storing some data about them. the list contains a column "User Name" of type Person or Group. I am able to save data for my "Domain1\user1" but When I ctry to save data for "Domain2\user1" it is giving me error "The user does not exist or is not unique."

I checked in user information List, there I only found user "Domain1\user1".

Can any one help we with this. 

Regards,
