Problem

When the user is created from t5connect and the same user try to login in translate5 with 'sso' provider, the translate5 does not know that this is the same user.

INFO: in sso we use auto-generate login because in translate5 one mail can exist for multiple logins.

Solution

The solution should be:

 - check for email as login after the iss and sub check fails.

• if the user exist, update the iss and sub
• if the user does not exist, try to save the user with the email as login
• if this also fails, auto-generate the login like before, and update the additional data
