here's what you need to do:
while logged in to the database with "myuser" run this:
show grants current_user();
if you don't see that myuser has select, insert, update, (blah ..)
access to user1.* and all other databases you want him to have access to
, then you need to grant access to myuser for the ones that are missing.
to grant access run something like this:
GRANT ALL ON scooby.* TO 'myuser''localhost' IDENTIFIED BY 'dooby'
lark -- net
To reply to me directly, delete "despam".
