  <p>Enable OmniAuth for an Existing User</p>
  
  <p>Existing users can enable OmniAuth for specific providers after the account is created. For example, if the user originally signed in with LDAP, an OmniAuth provider such as Twitter can be enabled. Follow the steps below to enable an OmniAuth provider for an existing user.</p>
  
  <pre><code>Sign in normally - whether standard sign in, LDAP, or another OmniAuth provider.
  Go to profile settings (the silhouette icon in the top right corner).
  Select the “Account” tab.
  ***Under “Connected Accounts” select the desired OmniAuth provider, such as Twitter.**    where ? I can't find!!!*
  The user will be redirected to the provider. Once the user authorized GitLab they will be redirected back to GitLab.
  </code></pre>
