Keystone configuration issue in orchestrator.ini

In the oslo generated orchestrator configuration file, the keystone configuration is not properly defined:

in [DEFAULT]

#auth_url = <None>

is defined in this section

in [keystone_authtoken]

#auth_uri = <None>

#identity_uri = <None>

are defined in this section. If you configure these parameters in these section appropriately the astara orchestrator doesn't start up.
Here is the output of the error:

Resolution:

Define the auth_url in the [keystone_authtoken] section of the orchestrator process.
