Dataedo Web SAML configuration with Duo

13th July, 2022

This guide will show how to configure Dataedo to work with a SAML identity provider. For this article, we'll be using Duo as the IdP, but similar steps can be taken for other providers too.

Initial configuration in Duo Admin Portal (SAML provider)

Open Duo Admin Portal and go to Enterprise Applications. Choose the Applications option, and click the Protect an Application button: Image title

On the new page, type in "generic saml" in the filter box, then press the Protect button in the Generic SAML Service Provider line: Image title

You should see a new page now: Image title

Scroll to the Service provider section. Type in a unique string (this can be e.g. the address of your Dataedo Web) in the Entity ID field - you will need this value later.

In the Assertion Consumer Service (ACS) URL field type in the address your Dataedo Web will be accessed on followed by /api/api/auth/assertion-consumer (for example https://your-Dataedo-Web.address/api/api/auth/assertion-consumer). Image title

In the Settings section, specify the name displayed for the users in Duo during login: Image title

Configure user access as usual, then click Save at the bottom of the page. Image title

Scroll back to the top of the page, then copy the adress marked as Metadata Url from the Metadata section - you will need it later.

Configuring SAML in Dataedo Web settings file

Find the installation path of Dataedo Web (default address is: *C:\Dataedo Web*), then go to Applications\API\ subfolder.

Right click and edit the appsettings.json file, and find the Saml2 section:

  "Saml2": {
    "IdPMetadata": "",
    "Issuer": "",
    "SignatureAlgorithm": "http://www.w3.org/2001/04/xmldsig-more#rsa-sha256",
    "CertificateValidationMode": "ChainTrust",
    "RevocationMode": "NoCheck"
  },

Paste the Metadata Url link in the IdPMetadata field (alternatively, paste in the path for the metadata xml file).

In the Issuer field, paste the address specified before in the Entity ID field field in Duo (you can check it in Service Provider > Identifier field in the application details in Duo Admin portal).

For the SignatureAlgorithm field paste in "http://www.w3.org/2001/04/xmldsig-more#rsa-sha256". If using a different signature algorithm, paste its link instead - for example, for RSA_SHA1 the field should have the http://www.w3.org/2001/04/xmldsig-more#rsa-sha1 value.

Find the Saml2Client section:

  "Saml2Client": {
    "DisplayName": "",
    "ClientUrl": "http://192.168.0.21:80"
  },

Fill the DisplayName field – this will be the name shown when logging in to Dataedo for the Identity Provider.

Make sure the ClientUrl field correctly leads to your Dataedo Web address.

After changes, the edited parts should look like this:

  "Saml2": {
    "IdPMetadata": "https://sso-a06d2d5e.sso.duosecurity.com/saml2/sp/DI7SDPCIHNSN9MOYP7QK/metadata",
    "Issuer": "Dataedo_PT_VM",
    "SignatureAlgorithm": "http://www.w3.org/2001/04/xmldsig-more#rsa-sha256",
    "CertificateValidationMode": "ChainTrust",
    "RevocationMode": "NoCheck"
  },
  "Saml2Client": {
    "DisplayName": "Duo Security",
    "ClientUrl": "https://127.0.0.1:443"
  },

Go to IIS Manager, and restart the Dataedo Web app for changes to take effect.

The next time you open Dataedo Web, you should have an option to login with Duo Security:

Clicking it will either take you to the Duo login page and then to your Dataedo Web page.
