Problem to set up OmniAuth with SAML

Hi,

I have problem to set up SAML authentication via OmniAuth using this guide:
http://doc.gitlab.com/ce/integration/omniauth.html

I’m having latest CE edition GitLab 7.11.4 b725318 (on Debian Wheezy), normal authentication and LDAP is working fine and I set this in /etc/gitlab/gitlab.rb

## For setting up omniauth
## see https://gitlab.com/gitlab-org/omnibus-gitlab/blob/629def0a7a26e7c2326566f0758d4a27857b52a3/README.md#omniauth-google-twitter-github-login

gitlab_rails['omniauth_enabled'] = true
gitlab_rails['omniauth_allow_single_sign_on'] = false
gitlab_rails['omniauth_block_auto_created_users'] = true
gitlab_rails['omniauth_providers'] = [
         {
            "name" => "saml",
             args: {
                     assertion_consumer_service_url: 'https://git-ssc.cz.oracle.com/users/auth/saml/callback',
                     idp_cert_fingerprint: '21:36:43:B4:A2:40:5A:A4:81:96:4B:94:79:8B:EE:14:FE:D7:A6:CC',
                     idp_sso_target_url: 'https://fedlogin-stage.oracle.com/fed/idp/samlv20',
                     issuer: 'https://git-ssc.cz.oracle.com',
                     name_identifier_format: 'urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress'
                   }
          }
 ]

gitlab-ctl reconfigure worked fine, but I cannot see SAML button in login, neither metadata or callback urls works (404 error),

Examining logs I found this in sidekick logs:

2015-06-10_10:09:30.34371 Could not find a strategy with name `Saml'. Please ensure it is required or explicitly set it using the :strategy_class option.

Any hints, ideas how to fix?

Thanks

I think I got it - although online documentation is already referring to SAML provider, it’s not yet available in latest omnibus release. I’ll try to upgrade when new omnibus release will be available
