Starting from v7.6 of Aurora, administrators are able to add and invite users from social networks.
In Users screen of AdminPanel, with Users not in domain selected, you can add users from social networks by pressing New User button. You'll be asked to enter login and password.
Login should be full email address. To avoid confusion for users, it's recommended to have the same e-mail address in both social network and in Aurora. This is, however, not a requirement (for instance, some social networks don't provide the user's email address).
The password you supply for the user will be needed for using Mobile Sync feature. They don't have to use this password for logging into Aurora, as they can simply login with their social account directly. It's your responsibility to provide the user with their new password. Users you add are not notified about their new accounts created, so you might want to use a different approach, by inviting them via emal.
In Users screen of AdminPanel, with Users not in domain selected, you can invite users from social networks by pressing Invite User button.
You'll be asked to enter their email address which has to correspond to their email address registered in the particular social network supported by your Aurora installation.
The user you invite will receive a message suggesting to log into your Aurora installation via one of the social networks supported. The message will contain a link, but it's not required to follow it, users can simply use login screen of your Aurora setup - but it will only work if specific external service returns user's email address. In case of Twitter, for example, using the invitation link will be required.
Initially, users will not be able to use email access and mobile sync as there is no email information or password set. If users might want that, they'll need to configure their mail and password.
NB: Before inviting users, make sure you have Email for invite notifications specified in AdminPanel - Invitations tab under Common screen. In case of tenant login, it's Tenant tab. If email address is not specified there, it will not be possible to send invites.
