Figure 5-6. Error: Username Already Exists
Note
If you are already a member of redhat.com, you can use the same user name and pass-
word. However, you must continue with the registration process to create your System
Profile.
Your username has the following restrictions:
Cannot contain any spaces
•
Cannot contain the characters &, +, %, or '
•
Is not case-sensitive, thereby eliminating the possibility of duplicate usernames differing
•
only by capitalization
In addition, the following restrictions apply to both your username and password:
Must be at least four characters long
•
Cannot contain any tabs
•
Cannot contain any line feeds
•
Passwords are case-sensitive for obvious reasons.
If you have already registered a machine and created a System Profile, you can add a
new machine to your account. Run the Red Hat Network Registration Client on the
new machine you wish to add, and enter your existing Red Hat Network username and
password. The new machine is added to your existing account, and you can log into Red
Hat Network with your username and password to view all your systems simultaneously.
