zend server ce: Reset username

zend server ce: Reset username

I installed zend server on Ubuntu 12.04. I went to localhost:10082 to view
the console. I set a user name and password and then I was logged into the
console. The next day I tried logging in, but I must have forgotten the
user name.
How can I reset the user name?
I tried:
(1) Uninstall with apt-get purge `dpkg -l | grep zend | awk '{print $2}'`
(2) Reinstall, but the console does not ask me to set a user name and
password.
I also tried resetting my password because I thought the username was correct
(1) /usr/local/zend/bin/php /usr/local/zend/bin/gui_passwd.php <your new
password>
But still no luck.
How Can I remove everything and restart all over so I can reset the user
name?
