+Feature: Multi-tenancy
+  I want to make sure that users from different tenants are isolated from each other,
+  so that each tenant's data and users remain private and secure.
+
+  Note:
+  All users are managed via LDAP and are assumed to exist.
+  Tests will use existing users without creating or deleting them.
+
+  Prepared LDAP users:
+    | user  | tenant   | group                |
+    |-------|----------|----------------------|
+    | alice | tenant-1 | new-features-lovers  |
+    | brian | tenant-1 | -                    |
+    | carol | tenant-2 | -                    |
+    | david | tenant-2 | release-lover        |
+
+
+  Scenario: users from the same tenant can see each other
+    When user "Brian" searches for user "ali" using Graph API
+    Then the HTTP status code should be "200"
+    And the JSON data of the response should match
