+h3(#pre-activated). Pre-activate user by email address
+
+You may create a user account for a user that has not yet logged in, and identify the user by email address.
+
+1. As an admin, create a user object:
+
+<pre>
+{
+ "email": "foo@example.com",
+ "username": "barney",
+ "is_active": true
+}
+</pre>
+
+2. Create a link object, where @tail_uuid@ is the user's email address, @head_uuid@ is the user object created in the previous step, and @xxxxx@ is the value of @uuid_prefix@ of the SSO server.
+
+<pre>
+{
+ "link_class": "permission",
+ "name": "can_login",
+ "tail_uuid": "email address",
+ "head_uuid: "user uuid",
+ "properties": {
+ "identity_url_prefix": "xxxxx-tpzed-"
+ }
+}
+</pre>
