Description of problem:
I've just installed RHEL5 and I receive a message like "connection problem" when
I try to register to RHN with an account with a short password (5 letters).
I have change the password and it works now.
But there is no error message even in log file /var/log/up2date.
It also doesn't like passwords with spaces, but gives the same generic
"connection problem" message.
