Problem while Creating a Repository Connection in RTC

I am trying to create Repository Connection using eclipse client on
RTC , so its asking for URL,Username and Password.I tried with ADMIN
as Username because its mandatory field.But i am getting error
message as UserName and Password is invalid.When I installed JAZZ
server by using Installation Manager, thats time its not asking for
any Username and Passwod.(I am usinmg trail version of RTC).
Please suggest me what process i have to follow.

Thanks In advance.

You need to first run "setup" on your server, which is when you will
specify your administrator user-id and password.

Instructions on how to run setup are provided by the readme file opened
by default at the end of your installation of the Jazz Team Server.
In particular, see the help topic "Running the setup wizard" in the
on-line documentation.
