Hi,
I am not familiar with the e-smith phpmyadmin rpm you mentioned but I used the standard phpmyadmin, install it into the path, Primary/html/phpmyadmin and then use htaccess and htpassword to enable users, as many as I want, each with their own private password.
In order to do this, you will need to find the htaccess rpm for e-smith or if you e-mail me directly, I can send it to you.
Just another way of doing it...
Cheers
