# OAuth Config
gitlab_rails['omniauth_enabled'] = true
gitlab_rails['omniauth_allow_single_sign_on'] = ['azure_oauth2']
gitlab_rails['omniauth_sync_email_from_provider'] = 'azure_oauth2'
gitlab_rails['omniauth_sync_profile_from_provider'] = ['azure_oauth2']
gitlab_rails['omniauth_sync_profile_attributes'] = ['name','email']
gitlab_rails['omniauth_block_auto_created_users'] = false
gitlab_rails['omniauth_auto_link_ldap_user'] = true
gitlab_rails['omniauth_external_providers'] = ['azure_oauth2']
gitlab_rails['omniauth_providers'] = [
 {
 "name" => "azure_oauth2",
 "args" => {
     "client_id" => "Client_ID",
     "client_secret" => "Client_Secret",
