Red Hat OpenStack 5 installation fails with packstack and external DB

Issue

With packstack from OSP5 beta packages the databases for the different service got created automatically when configure an external DB server and set CONFIG_MYSQL_INSTALL=n .

With the packstack version in RHEL6.5 OSP5 GA the DBs do not get created automatically. We upgraded Packstack to GA version:

openstack-packstack-puppet-2014.1.1-0.36.dev1220.el6ost.noarch
openstack-packstack-2014.1.1-0.36.dev1220.el6ost.noarch
openstack-packstack-doc-2014.1.1-0.36.dev1220.el6ost.noarch

This is how we execute Packstack:

packstack --timeout=1800 --debug --answer-file=packstack.txt

And this is the error we get:

10.1.20.47_keystone.pp:                           [ ERROR ]
