How to limit use of same email for different users

 

You can set Max accounts when authenticating with email matching. This setting allows two or more users to have same email for login:

  1. When the password differs, user is uniquely defined and can authenticate successfully.
  2. When the passwords are the same, user will NOT be logged in - instead will be asked to enter full username.
  3. When multiple users are matched, the number of matched users is checked against setting Max accounts when authenticating with email matching - if number of matched users is bigger than the limit, the authentication will fail, otherwise succeed.

TIP: Setting Enable email matching on authentication must have default value ("Yes") in order to test this.

Step 1

Click Security in Configuration menu.

Step 2

Set Max accounts when authenticating with email matching to "2" and click "Save" button.

Step 3

Set testuser1 email tim@islonline.com and password test1.

Step 4

Set testuser2 email tim@islonline.com and password test2.

Step 5

Login with tim@islonline.com and password test1 - you should be logged in as testuser1.

Step 6

Login with tim@islonline.com and password test2 - you should be logged in as testuser2.

Step 7

Set testuser3 email tim@islonline.com and password test3.

Step 8

Login with tim@islonline.com and test3 - you should get "Unable to login with user "tim@islonline.com". Please use full username: \\\username or \\domain\username".
