QPR ProcessAnalyzer can use federated authentication with the SAML 2.0 protocol. When using the federated authentication, QPR ProcessAnalyzer works as a service provider (SP), and uses compatible external identity providers (IdP) to provide user identity (i.e. authenticating users). Commonly used identity providers are Azure AD and Microsoft Active Directory Federation Services (ADFS).

General

When QPR ProcessAnalyzer is configured as a SAML 2.0 service provider (SP), users can authenticate to QPR ProcessAnalyzer via the configured SAML 2.0 identity provider (IdP) by clicking Log in Using SSO button in the login screen. This redirects users to the identity provider for authentication. When the authentication is done, users are redirected back to QPR ProcessAnalyzer where user is then logged in.

Alternatively, QPR ProcessAnalyzer can automatically redirect users to the identity provider, so that users won't see the QPR ProcessAnalyzer's login screen. This automatic redirection occurs, when accessing the url /qprpa/api/saml, e.g. https://customer.onqpr.com/qprpa/api/saml. Redirection to this url can be configured to IIS, when users access the server name only, e.g. https://customer.onqpr.com.

When a user logs in to QPR ProcessAnalyzer for the first time, user account is created to QPR ProcessAnalyzer user management. This account can only log in using the federated authentication, because the user account doesn't have a password in QPR ProcessAnalyzer. User accounts are matched between QPR ProcessAnalyzer and the identity provider using usernames.

Notes regarding the federated authentication:

  • QPR ProcessAnalyzer needs to be configured to use https when SAML authentication is used.
  • QPR ProcessAnalyzer only supports setup using SAML metadata (e.g. setup using a public key is not supported).
  • QPR ProcessAnalyzer only supports SAML POST binding (e.g. SAML redirect binding is not supported).
  • When QPR ProcessAnalyzer has been configured to use an identity provider, QPR ProcessAnalyzer will fully trust information coming from the identity provider.
  • Currently the logout request to IdP is not supported by QPR ProcessAnalyzer.
  • SAML AuthnRequests are not signed (by QPR ProcessAnalyzer), and SAML Assertions must be signed (by the IdP) to be accepted by QPR ProcessAnalyzer.

Configuring SAML to QPR ProcessAnalyzer

To configure SAML authentication, both QPR ProcessAnalyzer and the identity provider service needs to be configured:

  1. QPR ProcessAnalyzer is configured by defining settings SAMLMetadataUrl, ServiceProviderLocation and optionally SAMLUserIdAttribute in the QPR ProcessAnalyzer configuration table.
  2. The identity provider configuration depends on which identity provide is used. See the chapters below for help how to configure Azure AD and ADFS as the identity provider.

If there are issues with the functioning of the authentication, please check the QPR ProcessAnalyzer logs.

Using Azure AD as Identity Provider

Azure Active Directory (AD) can be used as an identity provider to login to QPR ProcessAnalyzer. Configuration scenario (discussed above) for Azure AD is to use metadata. Following configurations are needed:

  1. Login to https://portal.azure.com, click Azure Active Directory, click App registrations and click New application registration.
  2. Define Name for the application, such as "QPR ProcessAnalyzer". Select Application type to be Web app / API. Define Sign-on URL to be https://SERVERNAME/api/samlsignin (where SERVERNAME is the name of your QPR ProcessAnalyzer server).
  3. When the Azure application has been created, from the applications settings click Properties.
  4. Click Azure Active Directory, click App registrations and click Endpoints. Copy the contents of the Federation Metadata Document field, and configure it to the QPR ProcessAnalyzer SAML_METADATA_URL setting (discussed above).

More information about Azure Active Directory: https://docs.microsoft.com/en-us/azure/active-directory/

Using ADFS as Identity Provider

ADFS (Active Directory Federation Services) can be used as an identity provider to login to QPR ProcessAnalyzer. For ADFS setup, follow the ADFS configuration guide in https://docs.microsoft.com/en-us/windows-server/identity/ad-fs/operations/create-a-relying-party-trust with the following notes:

  • Step 4: Select option Enter data about the relying party manually as metadata is not available.
  • Step 5: Name can be chosen freely.
  • Step 7: Disable option Enable support for the WS-Federation Passive protocol. Select option Enable support for the SAML 2.0 WebSSO protocol and define url https://SERVERNAME/api/samlsignin where SERVERNAME is the QPR ProcessAnalyzer server hostname.
  • Step 8: Define url https://SERVERNAME/api/samlsignin where SERVERNAME is the QPR ProcessAnalyzer server hostname.
  • Step 11: Select option Configure claims issuance policy for this application.

Example: 

c:[Type == "http://schemas.microsoft.com/ws/2008/06/identity/claims/windowsaccountname", Issuer == "AD AUTHORITY"]
=> issue(store = "Active Directory", types = ("http://schemas.xmlsoap.org/ws/2005/05/identity/claims/upn", "http://schemas.xmlsoap.org/claims/CommonName", "http://schemas.xmlsoap.org/ws/2005/05/identity/claims/emailaddress", "http://schemas.xmlsoap.org/claims/Group"), query = ";userPrincipalName,displayName,mail,tokenGroups;{0}", param = c.Value);
