Hi,
According to your tutorial,
http://www.redhat.com/docs/manuals/database/RHDB-2.1-Manual/guitools/x454.html
we need to provide the password of postgres when we
log in as 'postgres'.But as we know ,the default
installation of postgresql has no password for User
'postgres'.

I have also created several user using the command
line to try to connect using the graphical tool,and it
also failed.

Can you help me out?
