SAML 2.0 Auth Module
A SAML 2.0 authentication module lets you configure YouTrack as a SAML Service Provider (SAML SP). SAML supports single sign-on (SSO) across multiple domains.
When you enable an SAML 2.0 authentication module in YouTrack:
Your users log in to YouTrack with the credentials that are managed in a specified third-party identity provider (SAML IdP).
Your YouTrack users have fewer accounts and passwords to remember.
New users with accounts in the connected service can create their own accounts in YouTrack.
YouTrack can also be set up as a SAML IdP. However, the instructions for the identity provider setup are not described here. To learn how to use YouTrack as a SAML IdP, see SAML 2.0.
The SAML 2.0 authentication module supports both service-provider (SP) and identity-provider (IdP) initiation for single sign-on (SSO). The login request is based on how the user signs in to YouTrack.
If the user signs in through an external login portal or access management provider (for example, OneLogin), the request is initiated by the IdP.
If the user signs in by clicking the button for the IdP in the YouTrack login page, YouTrack initiates the request as SP.
To support this behavior, the
RelayState parameter for your SAML IdP must be empty. If you set a value for this parameter in the configuration for your IdP, the redirection to the internal Hub service results in a
Can't restore state error.
Add a New SAML 2.0 Authentication Module
To add a SAML 2.0 Authentication module:
In a service that you plan to use as a SAML identity provider for YouTrack Server, retrieve its parameters as the IdP.
If the IdP service does not provide a fingerprint of their certificate, create it applying SHA256. For example, you can use SAML Tool
In YouTrack Server, open thepage.
Click the New module button, then select SAML 2.0 from the list.
In the dialog, specify the parameters for the IdP service, then click the Create button.
The SAML 2.0 authentication module is created and enabled.
Configure the auth module by providing the names of the SAML attributes for user accounts in the Attributes section of the page.
The first section of the page displays settings that identify the authentication module and let you manage the connection to the SAML service.
Displays the type of service that is enabled for authentication in YouTrack. Built-in Authorization means that this module is provided by the internal Hub service and is not installed separately.
Stores the name of the authentication module. Use this setting to distinguish this module from other authentication modules in the Auth Modules list.
Displays the image used for the button that a user clicks to log in to YouTrack with a their account in the connected authorization service. You can upload a JPG, GIF or PNG file. The image is resized to 48 x 48 pixels automatically.
SAML SSO URL
The URL that YouTrack uses to redirect to the external identity provider. YouTrack only supports HTTP-redirect binding for sign-on.
IdP entity ID
The entity ID of the external identity provider.
The SHA-256 fingerprint of the identity provider SAML certificate. Use the SAML XML Metadata from your identity provider to generate the fingerprint.
SP entity ID
The URL that identifies YouTrack as a service provider.
Selects an SSL key that can be used to verify the identity of your YouTrack installation to the authentication service. When used, all requests that are sent to the identity provider from YouTrack are signed using the corresponding SSL certificate.
This list only displays keystores that have been imported into YouTrack. For more information, see SSL Keys.
The assertion consumer service URL used by YouTrack as a service provider.
The URL that YouTrack uses to provide metadata to the external identity provider.
The user who is responsible for the SAML 2.0 service provider configuration. The email address that is associated with this user account must be verified in YouTrack.
Attribute Mapping Settings
Settings in the Attributes section of the page let you map attributes for user accounts in the SAML service to fields that are stored in Hub accounts.
The name of the SAML attribute that stores the username.
The name of the SAML attribute that stores the email address.
Email verification state
Determines whether email addresses that are returned by the authentication service are stored as verified or unverified.
The name of the SAML attribute that stores the first name of the user.
The name of the SAML attribute that stores the last name of the user.
The name of the SAML attribute that stores the full name of the user.
Maps to the attribute that stores group membership assignments in the connected authorization service.
When this value is specified, you can map and sync group memberships in the authorization service with corresponding groups in Hub. For details, see Group Mappings.
The following options are located at the bottom of the page. Use these settings to manage Hub account creation and group membership, and to reduce the loss of processing resources consumed by idle connections.
Enables creation of Hub accounts for unregistered users who log in with an account that is stored in the connected authorization service. YouTrack uses the email address to determine whether the user has an existing account.
Determines how Hub sets the verification status of an email address when the authentication service does not return a value for this attribute.
Adds users to a group when they log in with an account that is stored in the connected authorization service. You can select one or more groups. New users that auto-join a group inherit all the permissions assigned to this group.
We recommend that you add users to at least one group. Otherwise, a new user is only granted the permissions that are currently assigned to the All Users group.
Sets the period of time to wait to establish a connection to the authorization service. The default setting is 5000 milliseconds (5 seconds).
Sets the period of time to wait to read and retrieve user profile data from the authorization service. The default setting is 5000 milliseconds (5 seconds).
Links to the Audit Events page in YouTrack. There, you can view a list of changes that were applied to this authentication module.
On the Group Mappings tab, you can map existing groups in the SAML service to the groups in Hub.
If you want to map groups in the SAML service to groups in Hub, you need to specify the Groups attribute that stores SAML group memberships in the Attribute Mapping section of the settings for this auth module.
When group mappings are configured, Hub checks for group memberships when users log in with accounts that are managed in the SAML service. Hub performs the following operations for each group from the SAML service that is mapped to a Hub group:
Users who are members of a mapped SAML group and are not members of the mapped Hub group are added to the group in Hub.
Users who are not members of a mapped SAML group and are members of the mapped Hub group are removed from the group in Hub.
Changes to group memberships in the authorization service are only applied in Hub when users log in using their accounts from the SAML service.
You can map multiple groups from the SAML service to a single target group in Hub. You can't map groups from the SAML service to more than one Hub group.
To map group from the SAML service to a group in Hub:
Open your SAML auth module.
Select the Group Mappings tab.
Click the Add mapping button.
The Add Mapping dialog opens.
Enter the name of the SAML group in the SAML group name field.
Select a group from the Target group list.
Click the Add button.
The mapping is added to the list.
The following sample configurations show you how to use the SAML 2.0 authentication module to support different user management scenarios.
Okta as SAML Identity Provider for YouTrack
Configuring Okta as a SAML IdP in YouTrack is an easy but not a straight-forward process. The trick is that to create an Auth module in YouTrack, you need to provide a unique URL for the IdP. However, in Okta, the IdP URL is specific for an application, and is generated when you create the application for the SAML SP. And to create an application for YouTrack as a SAML service provider in Okta, you need the unique URL that is generated in YouTrack only when you create the Auth module for Okta. This "URL loop" results in the loop in the configuration procedure: You create an application in Okta with a fake URL for YouTrack to generate the IdP URL, then you create an auth module in YouTrack to generate the SP URL, and after that you can provide the actual SP URL from YouTrack in the Okta application.
Okta supports two protocols for handling federated single sign-on, both of which are supported for authentication with YouTrack.
The setup described here uses the SAML protocol. The settings for this module are preconfigured for generic connections with various SAML providers. Additional configuration for SAML authentication with Okta is required.
The Okta Auth Module supports the OpenID Connect (OIDC) protocol. The settings for this module are preconfigured to support direct connections with the Okta service. With this module, you need to register Hub as a client application in Okta, but everything else relatively easy to set up.
Your choice of protocol depends mainly on your use case, but OIDC is generally recommended for new integrations.
To use Okta as IdP for YouTrack Server:
In Okta, create a new application for YouTrack Server service. Use any URLs for YouTrack Server as the SP. You need to correct it later. See the Okta documentation for setting up SAML application.
When you created the application, click the View Setup Instructions button to open a page with the parameters of your Okta IdP:
Download the certificate of your Okta IdP.
Create a fingerprint for the Okta certificate applying SHA256. For example, you can use SAML Developer Tools.
In YouTrack Server, openpage.
Click the New module button, then select SAML 2.0 in the drop-down list.
A New Module dialog is displayed in the right side-panel.
In the displayed dialog, specify the parameters of your Okta IdP. Click Create.
Configure the new module: Set up the SAML attributes.
Switch back to Okta. Edit the YouTrack application by storing the URLs that are generated during the creation of the authentication module. The settings in Okta should be configured as follows:
Single Sign On Url
Enter the ACS URL from the authentication module in Hub.
Use this for recipient and destination URL
Enable this option.
Enter the SP entity ID from the authentication module in Hub.
Assign the YouTrack application to groups and users that should be able to log in to YouTrack with Okta credentials.
That's it. Now the users can log in to YouTrack with their Okta credentials.
YouTrack as SAML Identity Provider for another YouTrack Service
If you have two YouTrack services, you can use one of them as a SAML Identity Provider and another one as the service provider.
In the YouTrack Server service that you use as the SAML IdP, open the Parameters of YouTrack as SAML 2.0 Identity Provider.page. For details about YouTrack as a SAML 2.0 Identity Provider, see
In YouTrack that you use as SAML service provider, open Auth Modules page.
Click New module, then, select SAML 2.0....
A New Module dialog is displayed in the right side-panel.
In the dialog, enter the parameters of the YouTrack service that you use as IdP, then click the Create button.
The new module is created.
The settings page for the new SAML auth module opens.
Configure SAML attributes:
In the Hub service that you are using as IdP, open the SAML 2.0 page from the Access Management section of the Administration menu, select the Registered Service Providers tab, then click the New service provider button.
Register the second YouTrack service as the SAML service provider.
To register the service provider, enter the same values that are currently stored in the settings for the SAML 2.0 authentication module. For more details, see Register a Service Provider.
You are all set! Now your users can log into the YouTrack SP with the credentials from the YouTrack service that you use as SAML IdP.
