SAML - Windows SSO authentication

The purpose of this document is to describe how to configure PhenixID server for federation with SAML2 using Windows SSO (Kerberos or NTLM) authentication.

Prerequisites

  • PhenixID Server configured according to this instruction: "Federation - Username and password"

  • Windows settings:
  • –  Install PAS on a Windows Server that is member of an active directory domain.
– Create service account
CN=phxid,CN=Users,DC=company,DC=local
  • – Change the service “PhenixID service” to be run by CN=phxid,CN=Users,DC=company,DC=local
  • – Register a DNS A record: 
A    phenixid.company.local    127.0.0.1
  • – Register SPN from a command prompt
:
    C:\Users\Administrator>Setspn -S HTTP/phenixid.company.local phxid

    Checking domain DC=company,DC=local
    Registering ServicePrincipalNames for CN=phxid,CN=Users,DC=company,DC=local

    HTTP/phenixid.company.local
    
Updated object

    C:\Users\Administrator>Setspn -S HTTPS/phenixid.company.local phxid

    Checking domain DC=company,DC=local
    Registering ServicePrincipalNames for CN=phxid,CN=Users,DC=company,DC=local
    
HTTPS/phenixid.company.local

  • – If testing with web browser directly on server, Loopback checks must be disabled. Do not use in prod environments!

    Example values used in the description above:
    http domain: phenixid.company.local
    
Service account: CN=phxid,CN=Users,DC=company,DC=local
    
(Change the above to match your environment)

Convert the Federation - Username and Password scenario to SAMLWindowsSSO

Open the Advanced tab and locate the Authentication - HTTP entry that was configured in the previous "Federation - Username and password" scenario.

Change the value of the name parameter from "PostUidAndPasswordSAML" to "SAMLWindowsSSO"

Click the plus sign next to "configuration" to add new parameters

Set "authProtocol" = "<Type of Windows SSO Protocol>"

<Type of Windows SSO Protocol> can either be set to "NTLM" or "Negotiate" (Kerberos).

  2. Delete the valve #1 (InputParameterExistsValidatorValve) and valve #3 (LDAPBindValve)
  3. Click Save
