SAML with ADFS

Discover how Pleasant Password Server will enhance KeePass for business

The following steps can be used to setup an configure SAML SSO, with ADFS (Active Directory Federated Services). Other providers can be used with SAML SSO as well, see the related links below.

This can use your existing AD/LDAP connection and allow these users to be authenticated once using LDAP credentials and not be prompted again if they are already signed in.

Applies to: Versions 7.9.9+, Enterprise+SSO

Initial ADFS Setup:

Use the reference link below to set up an ADFS environment:

Requirements:

An environment with 2 machines:

  • A server acting as:
    • Domain Controller (DC), Directory Name Service (DNS), and Active Directory Federation Services (ADFS) server
  • A server acting as:
    • the Service Provider (or Relying Party)
    • with Pleasant Password Server installed

Setup Overview - Configure SAML SSO for ADFS

  • Create a Group Managed Service Account (GMSA) for use by ADFS
  • Create and install a certificate (3rd-Party / Self-Signed) for ADFS to use
  • Install the ADFS server role
  • Configure ADFS with the certificate and GMSA previously created
  • Add DNS records

Part 1 - Enable SAML in Password Server

Activate External Authentication:

  1. Go to the configuration page:
    • Users & Roles > Authentication Services
  2. Click Add SAML Configuration
  3. Provide an Issuer Name value
    • This value identifies your Pleasant Password Server application to the Identity Provider (ADFS), for example:
      • https://fs.mydomain.com/adfs/services/trust
    • Alternatively, some providers may allow this:
      • Pleasant Password Server
    • This value will be needed during step 2
    •  Edit SAML SSO Configuration
  4. Adjust the SSO Session Lifetime
    • If using Single Log Out (SLO), this value should be increased so the the session data is kept longer
    • However, if users are signing out often, i.e. daily, this value does not need to be larger
  5. (optional) Provide a certificate for digitally signing SAML requests and responses
    • Single Log Out (SLO) on ADFS requires that the requests be signed
    • See the addendum sections below for instructions on creating and configuring a signing certificate
      • Note: only .pfx or .p12 formats are accepted currently. Use the steps mentioned here to convert (Option A, step 2).
    • This certificate can be a self-signed certificate for ADFS
    • Be sure that your IIS user account (or AppPool) has read permissions to the imported certificate
  6. Save the configuration
  7. Another screen will show the SAML Configuration values:
    • For example:
    • SAML Configuration Review
    • Save the values for:
      • Issuer Name, Assertion Consumer Service URL, and Single Log Out Service URL
    • If using a certificate for signing you will also need to export the public key
    • If the URLs are directed to localhost, but this is not the URL you intend to use then you should sign in via that URL first

  • Users imported from the same Active Directory that AD FS is using will automatically be able to sign-in via AD FS
  • Users MUST be manually imported OR manually sign-in to Password Server if auto-import is enabled before AD FS sign-in is possible
  • If not importing users, the username must match the value of the SAM Account Name that AD FS is using
  • Users may still sign-in locally instead of using AD FS
  • If Single Log Out was configured, then signing out of Password Server will also sign the user out of AD FS (and other AD FS sessions)
  • To sign in or out of Password Server and other applications configured to use AD FS, use this page:
