Feature #4637
Updated by Peter Amstutz over 9 years ago
The SSO server has a (at least partial) capability to link multiple external provider accounts to the same user account. However, we currently bypass this capability and store the user id directly on the user record in "identity_url". We should:
* Remove the "identity_url" column and migrate it's contents to the 'authentications' table
* Enable users who are already logged in with one account to link additional accounts by logging in to other providers.
