associating SQL database user to SQL Login

Need help from an SQL Coder/DB expert for 1 hour or so. I am trying to move a database from one machine to another. I have moved the mdf/log files to the NEW server under database name 'tibcodb'and attached the database. The NEW database has a user 'tibco' that owns most tables. I have created new SQL Login 'tibco' on new database that has same name as user on old database. I then ran: sp_change_users_login 'update_one', 'tibco', 'tibco' This gave my new SQL login 'tibco' access to the database. My problem is that if I go to database 'tibcodb' -> Users -> and select user tibco - there is stall no associated Login. Thisis a big problem for me. Need help on how to solve this.
