OpenAM Authentication via Gosuslugi Portal

Original article: https://github.com/OpenIdentityPlatform/OpenAM/wiki/Login-via-“Госуслуги-РФ”-OAuth2-Identity-Provider

Preparation

Register an Organization on the Gosuslugi Portal

In order to use authentication through the ESIA, you need to register your organization on the Gosuslugi portal. To do this, you need to have a confirmed account of the head of the organization on the portal.

Next, you need to register your information system on the ESIA technology portal. To do this, go to the link https://esia.gosuslugi.ru/console/tech and authenticate with the account of the head of the organization. On the “Информационные системы” tab, click “Добавить систему” and fill in the properties on the link. The main thing to pay attention to is the system mnemonic, i.e. client_id, system URL - a list of allowed URLs to which redirection will be performed after successful or unsuccessful authentication in ESIA, as well as the algorithm of electronic signature formation - must be GOST3410_2012_256.

The process is described in more detail in document https://digital.gov.ru/ru/documents/6190/ section 3.1.1

Send System Registration Application to the Ministry of Digitization

After you have registered an information system, you must obtain a certificate from an accredited certification center (List of accredited certification centers at https://digital.gov.ru/ru/activity/govservices/certification_authority/).

The algorithm of electronic signature formation is GOST R 34.10-2012. The certificate must contain the OGRN of the legal entity that is the operator of the information system and can be issued for the employee of the legal entity or for the organization.

Next, you need to fill an application to gain access to the test environment as described in https://digital.gov.ru/ru/documents/4244/ paragraph 9 and send it to the e-mail address of the Ministry of Digitization.

After your system is registered in the test environment, you can proceed to OpenAM configuration.

OpenAM Installation

If you have already installed OpenAM, you can skip this section. For demonstration purposes, we will configure OpenAM in a Docker container.

Network Setup

Add the OpenAM hostname and IP address to the hosts file

127.0.0.0.1 openam.example.org

On Windows systems, the hosts file is located at C:Windows/System32/drivers/etc/hosts; on Linux and Mac it is located at /etc/hosts.

Install OpenAM in Docker

Start the Docker image of OpenAM by mounting the key and certificate issued earlier to the container.

docker run -h openam.example.org -p 8080:8080 --name openam \
 -v ./openam-esia.key:/usr/openam/esia/openam-esia.key:ro \.
 -v ./openam-esia.pem:/usr/openam/esia/openam-esia.pem:ro openidentityplatform/openam:latest

Once the OpenAM server is running, perform the initial configuration by running the following command and wait for the configuration to complete.

docker exec -w '/usr/openam/ssoconfiguratortools' openam bash -c \
'echo "ACCEPT_LICENSES=true
SERVER_URL=http://openam.example.org:8080

DS_DIRMGRDN=cn=Directory Manager

OpenAM Configuration

Setup ESIA Authentication Module

Open the OpenAM administrator console at http://openam.example.org:8080/openam. In the login field enter the amadmin value, in the password field enter the value specified in the ADMIN_PWD setting, in this case passw0rd.

In the console, select the root realm and then select Authentication → Modules from the left menu. In the opened list, click the Add Module button.

Enter the module name, for example, esia and the module type - OAuth 2.0 / OpenID Connect.

Press the Create button . Fill in the settings according to the table:

Configuring the ESIA Authentication Chain

Open the OpenAM admin console, select realm and from the left menu select Authentication → Chains . Click the Add Chain button and enter a name for the chain, for example esia . Click the Create button.

Press the Add a Module button.

Add module esia , Criteria set to Requisite. Press the `OK button .

Test the solution

Logout the OpenAM admin console, and open the ESUA authentication chain link: http://openam.example.org:8080/openam/XUI/?service=esia. If everything is configured correctly, you will be redirected to the ESIA authentication portal. Enter the user’s credentials. After successful authentication to the ESIA, the ESIA will request consent to access the data passed in the scope parameter. After accepting the consent, you will be redirected to the OpenAM console with the user’s ESIA credentials.
