Description of problem:
Unable to authenticate with user/admin after running foreman-installer.  I originally was hitting this using rhel-osp-installer.  It fails in puppet because it needs to authenticate over the API.  I tried using foreman-installer directly to take rhel-osp-installer/staypuft out of the picture and still end up with the same situation where I cannot authenticate as the admin user.

Version-Release number of selected component (if applicable):
[root@staypuft ~]# rpm -qa | grep foreman
foreman-proxy-1.6.0.21-1.el6sat.noarch
foreman-installer-1.5.0-0.4.RC2.el6ost.noarch
foreman-1.6.0.29-1.el6sat.noarch
rubygem-foreman_api-0.1.11-6.el6sat.noarch
foreman-postgresql-1.6.0.29-1.el6sat.noarch
foreman-selinux-1.6.0.3-1.el6sat.noarch


How reproducible:
Always

Steps to Reproduce:
1. Apply workaround for bug 1121697
2. Run foreman-installer -i
3. Disable configuration for foreman_plugin_bootdisk, foreman_plugin_setup (rpms not provided), so the only configuration items are: puppet, foreman, foreman_proxy.
4. Save and run

Installer completes, with the usual message, including:

  * Foreman is running at https://staypuft.example.org
      Default credentials are 'admin:changeme'

Actual results:
Trying to log in to the web UI gives "Incorrect username or password".  

Trying to authenticate in the rails console fails, although the user is present -

[root@staypuft ~]# su - foreman --shell /bin/bash
-bash-4.1$ cd /usr/share/foreman
-bash-4.1$ scl enable ruby193 'RAILS_ENV=production rails console'
