Users are displayed in EEM however they are not visible in the SOI console.
The user defined in the Active Directory may be defined in the format of user id, lastname, or firstname. SOI will only display users based on how they are defined in Active Directory.
Verify in Active Directory, how the users are defined in Active Directory. The users may be defined in the format of user id, last name, or first name. In the SOI console, go to the user tabs and then search on the users based on the format found in Active Directory.
