How it works

As already know the SSO module will allow users to login on your site via a social provider. Below a couple of cases how the module will handle the login and what it will do.

The Login process

1. The user clicks on of the social provider that are enabled.
2. The user will redirect to the social provider and will be asked for his login.
3. When the user enters the correct credentials, the user will be redirect to the EE site
4. On the main EE site, the SSO module will check if the user exists.
5. If the user does not exists:
   1. if member registration has been disabled.
      1. an error will be showed
   2. if member registration has been enabled.
      1. there will be a new member profile created for the user
      2. and a connect link will be made between the social provider and the EE site.
6. If the user exists
   1. if the setting "Allow social login to merge with non social accounts" is set to no there will be shown an error on the screen and the user will be asked to enter a new email address.
   2. if the setting "Allow social login to merge with non social accounts" is set to yes the user will be logged in on the account that already exists on the EE site.
   3. if the user has an account, that is connected to a social provider, it will always login on the existing account.
