Hi Alain,
and welcome to the community. Generally speaking the user is not known if you didn’t install the correct seed data (seed data is the data you write to the database during install; there are different readers for different types of installations). So chances are that you selected a different type of installation during install between both systems (there is an option to install including demo data - which includes the admin user - or without).
I am suspecting that that is what is causing the difference in your case. So a re-installation may be the easiest solution. It may also be that locally you weren’t able to write to the database during install (the logs should have shown alot of errors then - you can check {scipio-folder}/runtime/logs/error.og for those). If that is the case, then it would be good if you checked your configuration or told us which options you have chosen during install.
If you wanted to install without seed data, then here’s a few thoughts: We generally recommend to use our demo data for your first installation and use it as a template to create your own “seed” data . But if you are sure that you want to run on a blank installation without having setup anything, then you can create an admin by running the following command from command line:
./ant load-admin-user-login
This will create a user login with admin privileges. After the initial login you will be asked for a new password. Please be aware, however, that in this case you will still need to manually setup your applications, add all permissions, setup your store & company info and such. So I really wouldn’t recommend it, unless you are sure that this is what you wanted to do
