}

In this file:
keystone/manifests/init.pp

this key defaults to this value:
 $sql_connection = 'sqlite:////var/lib/keystone/keystone.db',

But the error above is thrown by:

  if($sql_connection =~ /mysql:\/\/\S+:\S+@\S+\/\S+/) {
    require 'mysql::python'
  } elsif($sql_connection =~ /postgresql:\/\/\S+:\S+@\S+\/\S+/) {

  } elsif($sql_connection =~ /sqlite:\/\//) {

  } else {
    fail("Invalid db connection ${sql_connection}")
  }

which reports the password missing, although I have not sorted out where that 
value is constructed.  When I tried to feed it in directly with this in my 
openstack::keystone class invocation:

#          sql_connection => $hesco_openstack::params::sql_connection,

I get:

Error: Could not retrieve catalog from remote server: Error 400 on 
SERVER: Invalid parameter sql_connection at 
/etc/puppet/modules/dessalines/openstack/manifests/init.pp:24 
on node controller.example.com

And here I remain stuck, looking for clues on how to move forward.  
Any help would be appreciated.
