Establishing connection

Antavo’s single sign-on (SSO) solution is implemented through the communication of three different servers.

First, the connection between the identity provider (IdP) and the Keycloak server needs to be established. The client’s IdP stores the login data of their users. SAML 2.0 / OIDC protocol is used for connecting this information with the Keycloak server.

The following table defines the attributes that are configurable at the integration of SSO.

Config Name

Required

Should be filled out by

Description

Service Provider Entity ID

(tick)

Client

The SAML Entity ID that the remote Identity Provider (IdP) uses to identify requests from this Service Provider. By default, this setting is set to the realms base URL <root>/realms/{realm-name}.

Single Sign-On Service URL

(tick)

Client

The SAML endpoint that starts the authentication process. If your SAML IdP publishes an IDP entity descriptor, the value of this field is specified there.

Single Logout Service URL

(error)

Client

The SAML logout endpoint. If your SAML IdP publishes an IdP entity descriptor, the value of this field is specified there.

Backchannel Logout

(error)

Antavo/Client

The SAML logout endpoint. If your SAML IDP publishes an IDP entity descriptor, the value of this field is specified there.

Backchannel Logout

(error)

Client

Toggle this switch to ON if your SAML IDP supports back channel logout.

NameID Policy Format

(error)

Client

The URI reference corresponding to a name identifier format. By default, Keycloak sets it to urn:oasis:names:tc:SAML:2.0:nameid-format:persistent.

Principal Type

(error)

Client

This attribute specifies which part of the SAML assertion will be used to identify and track external user identities. It can be either Subject NameID or SAML attribute (either by name or by friendly name). Subject NameID value can not be set together with urn:oasis:names:tc:SAML:2.0:nameid-format:transient NameID Policy Format value.

Principal Attribute

(error)

Client

If a Principal type is non-blank, this field specifies the name ("Attribute [Name]") or the friendly name ("Attribute [Friendly Name]") of the identifying attribute.

Allow create

(error)

Client

Allow the external identity provider to create a new identifier to represent the principal.

HTTP-POST Binding Response

(error)

Antavo/Client

Controls the SAML binding in response to any SAML requests sent by an external IDP. When OFF, Keycloak uses Redirect Binding.

HTTP-POST Binding for AuthnRequest

(error)

Antavo/Client

Controls the SAML binding when requesting authentication from an external IDP. When OFF, Keycloak uses Redirect Binding.

Want AuthnRequests Signed

(error)

Antavo

When ON, Keycloak uses the realm’s keypair to sign requests sent to the external SAML IDP.

Signature Algorithm

(error)

Client

If Want AuthnRequests Signed is ON, the signature algorithm to use.

SAML Signature Key Name

(error)

Antavo

Signed SAML documents sent using POST binding contain the identification of signing key in KeyName element, which, by default, contains the Keycloak key ID. External SAML IDPs can expect a different key name. This switch controls whether KeyName contains: * KEY_ID - Key ID. * CERT_SUBJECT - the subject from the certificate corresponding to the realm key. Microsoft Active Directory Federation Services expect CERT_SUBJECT. * NONE - Keycloak omits the key name hint from the SAML message.

Force Authentication

(error)

Antavo

The user must enter their credentials at the external IDP even when the user is already logged in.

Validate Signature

(error)

Antavo

When ON, the realm expects SAML requests and responses from the external IDP to be digitally signed.

Validating X509 Certificate

(error)

Antavo

The public certificate Keycloak uses to validate the signatures of SAML requests and responses from the external IDP.

Sign Service Provider Metadata

(error)

Antavo/Client

When ON, Keycloak uses the realm’s key pair to sign the SAML Service Provider Metadata descriptor.

Pass subject

(error)

Client

Controls if Keycloak forwards a login_hint query parameter to the IDP. Keycloak adds this field’s value to the login_hint parameter in the AuthnRequest’s Subject so destination providers can pre-fill their login form.

Attribute Consuming Service Index

(error)

Client

Identifies the attribute set to request to the remote IDP. Keycloak automatically adds the attributes mapped in the identity provider configuration to the autogenerated SP metadata document.

Attribute Consuming Service Name

(error)

Client

A descriptive name for the set of attributes that are advertised in the autogenerated SP metadata document.

SAML 2.0 metadata configuration

The following is an example of metadata for a SAML 2.0 system entity acting as a service provider. This xml XML is exportable from the IdP side and these data need to be sent over to Antavo to Antavo’s administrator – they will import it to Keycloak’s server for you.

Configuring the SSO

...

module

Next, a connection needs to be established The next step is to establish the connection between the Antavo platform and the Keycloak server .
The platform and the Keycloak are connected through through the configuration of the SSO module in the Backoffice. This can be accessed from the Backoffice’s Module page by typing Single Sign-On or SSO into the search field.

...

The following use case illustrates setting up the SSO provider on a demonstration account. This is configured by the Antavo administrators.Find the configuration page of the SSO module by clicking on the (blue star) icon in the sidebar and typing 'SSO' into the search bar of the Modules menu.

...

The page provides the interface to set up the connection with the following fields:

  • URL

  • Realm

  • Client ID : platform

  • Client secret: this
    This is generated during the Keycloak configuration.

  • Federation field : uid (default)Scopes: openid profile email- default value is uid

  • Scopes

Info

Please contact the Antavo Service Desk before you start configuring the module or want to make changes in the settings.

Setting up SSO login for Backoffice users
Anchor
user-login
user-login

The SSO Source and SSO ID of backoffice Backoffice users have to be added on the user editor interface to enable SSO login. Please note, that SSO login is enforced for all users by default, meaning users can log in to the backoffice Backoffice through SSO unless you turn off this restriction.
Please find instructions on the configuration of these settings here.
