[Mitaka] 'AttributeError: name' when using multiple domain with LDAP driver

I get 'AttributeError: name' when using multiple domain with LDAP driver.
Specifically, when I click 'Create Project', 'Manage Members', 'Modify Groups', 'Edit Project' and 'Modify Quotas' button on the 'Projects' page of 'Identify' menu, horizon makes those error messages below.

It doesn't seem to be related to keystone since there is no error message from keystone node and I can do those operations using CLI without any problem.
