From the openSUSE bug report:
Jose Castro Leon from CERN reported a vulnerability in the way the Keystone LDAP backend authenticates users. When provided with an empty password, the backend would perform an anonymous LDAP bind that would result in successfully authenticating the user. An attacker could therefore easily impersonate and get valid tokens for any user. Only Keystone setups using LDAP authentication backend are affected.
