I upgraded now completely on the Juno release. A different problem now appears.

Due to the LDAP identity backend driver for the default domain, user logins are used for trustor_user_ids. This work without any problems as long as the login name does not contain the dot character. Unfortunately are most of our users created using a pattern like givenname.surename.

This leads then to the following error in keystone:

2015-01-02 16:19:45.587 3984 WARNING keystone.common.wsgi [-] Invalid input for field 'trustor_user_id'. The value is 'marcus.klein'.

And then the heat-engine failes with:
