-h2. Configure the SSO server
+h2(#configure). Configure the SSO server
-First, copy the example configuration file:
+The package has installed three configuration files in @/etc/arvados/sso@:
<notextile>
-<pre><code>~/sso-devise-omniauth-provider$ <span class="userinput">cp -i config/application.yml.example config/application.yml</span>
-</code></pre></notextile>
+<pre><code>/etc/arvados/sso/application.yml
+/etc/arvados/sso/database.yml
+/etc/arvados/sso/production.rb
+</code></pre>
+</notextile>
+
+The SSO server runs from the @/var/www/arvados-sso/current/@ directory. The configuration files in @/etc/arvados/sso/@ are symlinked to @/var/www/arvados-sso/current/config/application.yml@, @/var/www/arvados-sso/current/config/database.yml@ and @/var/www/arvados-sso/current/config/environments/production.rb@.
The SSO server reads the @config/application.yml@ file, as well as the @config/application.defaults.yml@ file. Values in @config/application.yml@ take precedence over the defaults that are defined in @config/application.defaults.yml@. The @config/application.yml.example@ file is not read by the SSO server and is provided for installation convenience only.
-Consult @config/application.default.yml@ for a full list of configuration options. Local configuration goes in @config/application.yml@, do not edit @config/application.default.yml@.

h3(#uuid_prefix). uuid_prefix
Generate a uuid prefix for the single sign on service. This prefix is used to identify user records as originating from this site. It must be exactly 5 lowercase ASCII letters and/or digits. You may use the following snippet to generate a uuid prefix:

+
+There are other configuration options in @/etc/arvados/sso/application.yml@. See the "Authentication methods":install-sso.html#authentication_methods section below for more details.
h2(#database). Set up the database
Generate a new database password. Nobody ever needs to memorize it or type it, so make a strong one:
<notextile>
-<pre><code>~/sso-devise-omniauth-provider$ <span class="userinput">ruby -e 'puts rand(2**128).to_s(36)'</span>
+<pre><code>$ <span class="userinput">ruby -e 'puts rand(2**128).to_s(36)'</span>
abcdefghijklmnopqrstuvwxyz012345689
</code></pre></notextile>
+Configure the SSO server to connect to your database by updating @/etc/arvados/sso/database.yml@. Replace the @xxxxxxxx@ database password placeholder with the new password you generated above. Be sure to update the @production@ section.
+
+<notextile>
+<pre><code>$ <span class="userinput">edit /etc/arvados/sso/database.yml</span>
+</code></pre></notextile>
+
Create a new database user with permission to create its own databases.
<notextile>
-<pre><code>~/sso-devise-omniauth-provider$ <span class="userinput">sudo -u postgres createuser --createdb --encrypted -R -S --pwprompt arvados_sso</span>
+<pre><code>$ <span class="userinput">sudo -u postgres createuser --createdb --encrypted -R -S --pwprompt arvados_sso</span>
Enter password for new role: <span class="userinput">paste-database-password-you-generated</span>
Enter it again: <span class="userinput">paste-database-password-you-generated</span>
</code></pre></notextile>
-Configure SSO server to connect to your database by creating and updating @config/database.yml@. Replace the @xxxxxxxx@ database password placeholders with the new password you generated above. If you are planning a production system, update the @production@ section, otherwise use @development@.
+Rails will take care of creating the database, based on the information from @/etc/arvados/sso/database.yml@.
+
+Alternatively, if the database user you intend to use for the SSO server should not be allowed to create new databases, the user and the database can be created like this:
<notextile>
-<pre><code>~/sso-devise-omniauth-provider$ <span class="userinput">cp -i config/database.yml.example config/database.yml</span>
-~/sso-devise-omniauth-provider$ <span class="userinput">edit config/database.yml</span>
+<pre><code>$ <span class="userinput">sudo -u postgres createuser --encrypted -R -S --pwprompt arvados_sso</span>
+Enter password for new role: <span class="userinput">paste-database-password-you-generated</span>
+Enter it again: <span class="userinput">paste-database-password-you-generated</span>
+$ <span class="userinput">sudo -u postgres createdb arvados_sso_production -E UTF8 -O arvados_sso -T template0</span>
</code></pre></notextile>
-Create and initialize the database. If you are planning a production system, choose the @production@ rails environment, otherwise use @development@.
+{% include 'notebox_begin' %}
+If you are installing on CentOS6, you will need to modify PostgreSQL's configuration to allow password authentication for local users. The default configuration allows 'ident' only. The following commands will make the configuration change, and restart PostgreSQL for it to take effect.
+<br/>
<notextile>
-<pre><code>~/sso-devise-omniauth-provider$ <span class="userinput">RAILS_ENV=production bundle exec rake db:setup</span>
-</code></pre></notextile>
+<pre><code>$ <span class="userinput">sudo sed -i -e "s/127.0.0.1\/32 ident/127.0.0.1\/32 md5/" /var/lib/pgsql/data/pg_hba.conf</span>
+$ <span class="userinput">sudo sed -i -e "s/::1\/128 ident/::1\/128 md5/" /var/lib/pgsql/data/pg_hba.conf</span>
+$ <span class="userinput">sudo service postgresql restart</span>
+</code></pre>
+</notextile>
+{% include 'notebox_end' %}
-Alternatively, if the database user you intend to use for the SSO server is not allowed to create new databases, you can create the database first and then populate it with rake. Be sure to adjust the database name if you are using the @development@ environment. This sequence of commands is functionally equivalent to the rake db:setup command above:
+h2(#reconfigure_package). Reconfigure the package
+
+Now that the @/etc/arvados/sso/application.yml@ and @/etc/arvados/sso/database.yml@ files have been updated, we need to reconfigure our installed package. Doing so will create and/or initialize the database and precompile the assets.
+
+On a Debian-based system:
<notextile>

-~/sso-devise-omniauth-provider$ <span class="userinput">RAILS_ENV=production bundle exec rake db:seed</span>
-</code></pre></notextile>
+<pre><code>~$ <span class="userinput">sudo dpkg-reconfigure arvados-sso</span>
+</code></pre>
+</notextile>
+
+On a Red Hat-based system, we need to reinstall the package instead:
+
+<notextile>
+<pre><code>~$ <span class="userinput">sudo yum reinstall arvados-sso</span>
+</code></pre>
+</notextile>
h2(#client). Create arvados-server client
Use @rails console@ to create a @Client@ record that will be used by the Arvados API server. The values of @app_id@ and @app_secret@ correspond to the values for @sso_app_id@ and @sso_app_secret@ in the "API server's SSO settings.":install-api-server.html#omniauth

-h2(#assets). Precompile assets
-
-If you are running in the production environment, you must precompile the assets:
-
-<notextile>
-<pre><code>~/sso-devise-omniauth-provider$ <span class="userinput">RAILS_ENV=production bundle exec rake assets:precompile</span>
-</code></pre>
-</notextile>

h2(#authentication_methods). Authentication methods
Authentication methods are configured in @application.yml@. Currently three authentication methods are supported: local accounts, LDAP, and Google+. If neither Google+ nor LDAP are enabled, the SSO server defaults to local user accounts. Only one authentication mechanism should be in use at a time.
