title: What SonarQube plugins support SSO?
body: <p>I see "Authentication and authorization can also be delegated to an external system: LDAP or Active Directory with the SonarQube LDAP Plugin, PAM with the SonarQube PAM Plugin or Crowd with the SonarQube Crowd Plugin. SSO is also supported through the SonarQube OpenID plugin" in <a href="http://docs.sonarqube.org/display/SONAR/Security" rel="nofollow">SonarQube documentation page</a></p>
  
  <p>It seems that only SonarQube OpenID plugin supports SSO.</p>
  
  <p>But I see about Active Directory plugin: "It automatically logs in user using Single Sign On (SSO) with Active Directory Credentials in Microsoft Active Directory Environments." <a href="https://github.com/SonarQubeCommunity/sonar-activedirectory" rel="nofollow">here</a>.</p>
  
  <p>Also "the LDAP plugin now supports Single Sign On (SSO)" from <a href="https://blogs.msdn.microsoft.com/visualstudioalm/2015/11/13/support-for-active-directory-and-single-sign-on-sso-in-the-sonarqube-ldap-plugin/" rel="nofollow">here</a>.</p>
  
  <p>My questions:</p>
  
  <ol>
  <li>Do Active Directory plugin or SonarQube LDAP Plugin supports SSO?</li>
  <li>Crowd plugin do not support SSO, right?</li>
  <li>Can I use Crowd plugin + some another plugin or tool to support SSO (For example OpenId plugin+Crowd plugin, LDAP Plugin+Crowd plugin)?</li>
  </ol>
  
  <p>I use Crowd to authentificate my services.</p>
