permission denied on object

I connect in my database "test" with the user "teste" by SQL QueryAnalyzer (localhost;DatabaseName=test;SelectMethod=cursor),
but when i run the SQL (select * from user) return the error
"SELECT permission denied on object 'user', database 'test', owner 'teste'.

I already put all permission to the user "user".

My database test has a table "user". The owners "teste" and the Types "User"
The user "teste" has all permission to the table "user" (select, update, insert ...)

what i need to do ? Whats wrong ?The user may possibly be denied access to the table or a member of a group that is denied access to the table or possibly a member of db_denydatareader.
