+== Allow users to have rights for shares of different domain
+
+Typically, preventing users to obtain rights for shares of another domain is a
useful security layer.
+However, in multi-tenancy deployments, this can be useful (for example,
students might be given access to a shared mailbox
+residing under the @university.edu domain with their @student.university.edu
address).
+
+Optional. Boolean. Defaults to false.
