I am trying the Neutron Rocky installation guide, setting up the tenant networks option. The OS is Centos 7.
After going through all configurations on the controller, the Neutron server fails to start with the following error message in its log: NoSuchOptError: no such option auth_admin_prefix in group [keystone] This baffles me. There is no file under /etc that contains the string auth_admin_prefix. This config variable has been deprecated since Newton at least. Where does it come from? How can I remove it? I see the string mentioned in a few launchpad bug descriptions, but only in the context of deprecation warnings. The associated stack trace is reproduced below, plus a few additional log messages at the beginning. While "__file__" and "here" (mentioned in bug 1722444[1]) don't seem to trip Neutron or Keystone, "auth_admin_prefix" does. Thanks for inputs. Bernd.
