Enable two-factor authentication to Identity Manager clients via SAML federation
This article is valid for Smart ID 20.11 and later.
This article describes how to enable two-factor authentication to the Smart ID Identity Manager clients Identity Manager Operator and Smart ID Self-Service.Â
This is solved by setting up a SAML 2.0 federation in Digital Access with Identity Manager as a Service Provider and an Identity Provider, such as Smart ID Digital Access component.Â
Prerequisites
Installations
Identity Manager must be set up:
Installed Identity Manager, see Install Identity Manager.
The identity provider must be set up. If Digital Access component is used, see here:
Installed Digital Access component, see Deploy Digital Access component
Network Time Protocol (NTP) of Digital Access component must be set up. See Deploy Digital Access component
Certificates
SSL server certificates for https communication:
For Identity Manager, SSL server certificate in PKCS#12 format.Â
Example:Â idm.p12
For Digital Access as identity provider, SSL server certificate and private key as PKCS#8 PEM files.Â
Example: Certificate: da.pem, Private Key: da.key.pem
SAML certificates for signing and encryption:
For Identity Manager, SAML certificate in PKCS#12Â format.Â
Example: idm.saml.p12For Digital Access as identity provider, SAML certificate and private key as PKCS#8 PEM files.
Example:Certificate: da.saml.pem, Private Key: da.saml.key.pemÂ
If you need instructions to create demo certificates or extract certificates to the required formats, see Create or extract certificates for SSL and SAML.
Set up Identity Manager as service provider
Set up authentication profile
To integrate Identity Manager with SAML SSO, the SAML authentication profile must be used.
In Identity Manager Admin, go to Authentication Profiles, and add a new profile with the type SAML SSO Core Object. See Set up authentication profile in Identity Manager.
Open the created authentication profile for editing.
Go to the Core Object Configuration tab and do the following settings:
In Identity template, select one or more core object types, for example, Employee and Contractor, on which the core object search will be performed. The first matching template will be used.
In User name field, select the core object field to match the user principal, for example UPN or Email. Identity Manager will use it to search the core object in the selected identity template.
In User display, enter fields in a comma separated list, for example FirstName, LastName. These fields are used to display the logged in user in Identity Manager Operator or Smart ID Self-Service.
Upload keystore file
The defined keystore file must contain the certificates and the private key used for signing and decryption.
A keystore is mandatory to configure. Trying to save a configuration without a keystore, triggers an error message.Â
Go to the SAML Configuration tab. Â
Under Keystore configuration, click the upload symbol, browse for the keystore file and select it.Â
In Password, enter the keystore password. If objects in the key store are protected with a password, then they must have the same password as the keystore.Â
When the keystore configuration has been uploaded, then Available key aliases shows a list of the aliases of all available private keys in the key store.
Create service provider metadata files
Each SAML federation can have multiple service providers, for example Identity Manager, Smart ID Self-Service and any other application to be included in the federation. Each service provider must have a metadata file.Â
For each service provider, do the following to create a metadata file:Â
Create a metadata file in .xml format, and give it a file name such as IdM_saml_metadata.xml.
Open the file for editing. Copy and paste the example file content from below.
Do the following changes:
In entityID: enter a meaningful name for the service provider, for example https://<idmhost>/sp.
Replace certificate data with the base64 encoded SAML certificate, for example idm.saml.pem.
In Location: enter the location like this:Â http://<idmhost>/saml/SSO/alias/<alias>.
For example:
http://<idmhost>/saml/SSO/alias/explorer
http://<selfservicehost>/saml/SSO/alias/self-serviceÂ
Or if both applications are on the same machine:
http://<idmhost>/idm/saml/SSO/alias/explorer
http://<idmhost>/selfservice/saml/SSO/alias/self-service

This table describes some elements and attributes of the Service Provider metadata xml file:Â
Element | Attribute | Description |
---|---|---|
EntityDescriptor | The common root element for definitions of IDP and SP. | |
 | entityID | By convention, a symbolic URL can be used both for an IDP and a SP but any identifier is allowed. The number of characters is limited to 1024. |
 | xmlns:md | Namespace definition of SAML V2.0 metadata. |
KeyDescriptor | Provides information about the cryptographic key(s) an entity uses for signing and encryption. The contents, including the certificate, follow the XML Signature standard. | |
 | use | Allowed values are "signing" and "encryption". This attribute is optional. If it is not used the assumption is that the same certificate is used for both signing and encryption. |
NameIDFormat | Elements indicate what SAML name identifier formats the service supports. | |
SPSSODescriptor: | Element for the definition of a SP. | |
 | protocolSupportEnumeration | Support for the SAML V2.0 protocol namespace. |
 | AuthnRequestsSigned | Indicates if the SAML request sent by the SP must be signed. This attribute is optional. Defaults to "false" if not set. |
 | WantAssertionsSigned | Indicates if the Assertion elements in the SAML response must be signed. This attribute is optional. Defaults to "false" if not set. |
The signature check is a fundamental security mechanism of the SAML protocol. Therefore, it is strongly recommended to set AuthnRequestsSigned and WantAssertionsSigned to true. | ||
AssertionConsumerService | The service the SP defines to process the SAML response. | |
 | Binding | Mapping of the SAML protocol message onto a standard communication protocol. Value "urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST" required. |
 | Location | The URI under which the endpoint is reachable. Must include the path /saml/SSO/alias/<alias>. |
 | index | A unique integer of the endpoint for reference in a protocol message. |
Upload service provider metadata files to authentication profile
After the metadata files have been created they must be uploaded to the authentication profile in Identity Manager Admin. Multiple service providers can be configured, for example for the different Identity Manager applications and any other applications to be included in the federation.Â
Open the SAML SSO authentication profile that was created earlier.
Go to the SAML Configuration tab. Â
Under Service Provider Configuration, do the following for each service provider:
Click on the + button to add a service provider.Â
In Service Provider Details, define the service provider as follows:Â
In Configuration file, click on the upload symbol and select the metadata file.Â
In Alias, enter a name to define the service provider. This must match the <alias> in the Location in the metadata file. If needed, multiple aliases can be given to the same application.
Example: explorer or self-service. ÂIn Alias for Signing Key and Alias for Encryption Key, enter the names of the private keys for signing and encryption that must be available in Available Key Aliases.Â
Additional configurations for Smart ID Self-Service
Configure SAML in Smart ID Self-Service
Smart ID Self-Service has additional configuration options directly in the program.Â
Multiple Self-Service instances with the same tenant, but different authentication methods, are allowed. If, for example, there are two Self-Service instances and both of them use the same tenant, one instance can use SAML whereas the other one doesn't.
Also, you can configure a button "Sign In with Single Sign-On" on the login page instead of automatically redirecting to the Identity Provider.
SAML and automatically redirecting are enabled by default, you can change this behavior in config.json.
To disable SAML for a Self-Service instance, add
"enabled": false
to its config.json. By default it is enabled.ÂTo turn of automatic redirecting to the Identity Provider, add
"enforced": false
to its config.json. By default it is enforced. This means that this instance of Self-Service will show a button "Sign In with Single Sign-On" on the login page. If SAML is disabled for this instance of Self-Service this property has no effect. With this option you can use Pre-Login Processes while having SAML enabled.
Example: config.json
/prime-ussp/assets/config/config.json
...
{
...
"saml": {
"enabled": true
"enforced": true
}
}
Â
Set up communication between Smart ID Self-Service and Identity Manager
Open the file \prime_ussp\WEB-INF\classes\application.yaml.
Adapt the baseUrl so that it points to where the Identity Manager main client is deployed. If you use HTTPS instead of HTTP you must ensure that the SSL server certificate of Identity Manager is trusted by the java environment that runs the Smart ID Self-Service (tomcat).
Make sure that cookie forwarding is activated, that is, that there are empty values for the property
sensitiveHeaders
for the SAML routes in the configuration file.This is the default configuration.
Example: application.yaml
prime: … baseUrl: http://localhost:8080/idm … zuul: … routes: … saml: path: /saml/** sensitiveHeaders: url: ${prime.baseUrl}/saml/
Â
Install Identity Provider server certificate
To have a secure communication between the identity provider and Identity Manager, server certificates must be provided by each server.Â
Example - Add server certificate in Digital Access component:Â
Log in to Digital Access Admin.
Go to Manage System > Certificates.
In Server Certificates, click Add Server Certificate…Â
Enter a Display Name and browse for the files, to define Certificate and Key:
Click Next > to finish the wizard.Â
Set up identity provider, for example Digital Access component
Import Identity Provider SAML certificate
Private keys are used to digitally sign SAML messages and encrypt their content. Both parties need their own key-pair that could be created in self-signed mode (for testing purpose) or received from a public key infrastructure (for productive systems).Â
Example - Enable Digital Access to use the SAML certificate for signing:
Log in to Digital Access Admin.
Go to Manage System > Certificates.
In Server Certificates, click Add Server Certificate…Â
Enter a Display Name and browse for the files, to define Certificate and Key:
Â
Click Next > to finish the wizard.
Optional: Create DNS name for identity provider
As identity provider, you can use any SAML2 compliant system. Follow the instructions of that software in order to configure it as SAML IdP. If you use Digital Access as identity provider, follow the steps here to create a DNS name.
Example - Create a DNS name for the Digital Access access point:
Log in to Digital Access Admin.
Go to Manage Resource Access >Â Global Resource Settings.
Go to the DNS Name Pool tab.
Add a new DNS name for the access point. Give the DNS name, for example idp.hag.local, and select the corresponding Digital Access server certificate, for example hag.local.pem.
Click Add and then Save. Â
Create SAML Federation
The identity provider must be configured to define the SAML federation with the service provider, using the metadata created in Identity Manager.Â
Example - Add service provider in Digital Access:
Go to Manage Resource Access > SAML Federation.
Click Add SAML Federation....
Enter a Display Name, for exampleÂ
IDENTITYMANAGER
.Check Acting as Identity Provider.
Uncheck Import metadata automatically.
Go to the Export tab.
Give a unique Entity ID: for exampleÂ
https://hag.local/idp
.Select the Signing Certificate, for exampleÂ
SAML IdP Signing
.Go to the Role Identity Provider tab and click Add service provider...
Verify that SAML 2.0 is checked.
Upload SAML 2.0 metadata, click Choose file and select the file that was created before (for example IdM_saml_metadata.xml). Click Next.
Confirm the message about the signer certificate by clicking Yes.
Click Finish Wizard.
Click on the created service provider, to open it.
The Display Name and Entity ID is now updated according to the metadata file.Â
Disable Require signed authentication requestÂ
Go to the Assertion Settings tab.
In Subject > Select source of subject: select E-mail. This is the unique identifier Identity Manager uses in standard cases, and will be used when Digital Access sends a SAML ticket to Identity Manager.
Go to the tab Manage Access Rules.
Select any suitable access rule or leave it as Any Authentication. Â
Click Finish Wizard and then Add.Â
Repeat the same steps to add Smart ID Self-Service as an additional service provider. Â
Download SAML metadata
After the service provider was configured successfully in the identity provider, the SAML metadata must be downloaded and uploaded in Identity Manager.
Example - Download the metadata from Digital Access:Â
Go to Manage Resource Access > SAML Federation.
Click on the created service provider, to open it.
Go to the tab Export.
Click Download metadata.
Upload the metadata file to the SAML Authentication Profile in Identity Manager and select the Type as METADATA. No File Properties needs to be configured for the identity provider meta-data.
Upload identity provider metadata to SAML authentication profile in Identity Manager
After the metadata files have been created they must be uploaded to the authentication profile in Identity Manager Admin. This section describes how to upload the identity provider metadata files.Â
Open the SAML SSO authentication profile that was created earlier.
Go to the SAML Configuration tab. Â
Under Identity Provider Configuration, do the following:
In Configuration File, click the upload symbol to browse for and select the metadata file that has been provided from the identity provider, for example downloaded from Digital Access.Â
In Attribute Type, select either option for where the authentication information shall be communicated:Â
NameIDÂ refers to the subject of a SAML response. Use an appropriate value that matches the desired field in the CoreObject.
Attribute Statement refers to attributes associated with the subject of a SAML response.
If Attribute Statement was selected, then also enter one or more names in Attribute Name.Â
