Cannot view user in the Security section of the database

How did you give him db_owner permission then?  There is a difference between an instance LOGIN and a database USER.  Are you sure you don't have the former and are missing the latter?

Forgot to attach screenshot. this zaj I have given him sysadmin permission

Hi,

Select the user to which you want to get displayed at your database.

go to properties - > User Mapping - > uncheck the database and check again

Check the DB_owner and click OK.

Your user should be displayed in the user column of the database where dbo is shown currently.

Thanks for your feedbacks.
One thing, this user zaj is sysadmin,could be that sysadmin user is not shown in the database's - security - user folder???
the reason is when i create a new user and add map them to a db, they are added but not this user.
Also when you see that screenshot, in the user column it shows dbo instead of zaj,why??

Did you Refresh the Security folder after giving him db_owner rights?
Also, check the login for the dbo. He might be him already.

yes i did, and i still cannot get this user in that security folder
