2018-03-08_23-45-22_SAMLv2 authentication process

You can configure the Remedy Single Sign-On (Remedy SSO) server to authenticate users through SAMLv2 authentication. SAML V2.0 is implemented by forming a Circle of Trust that comprises a Service Provider (SP) and an Identity Provider (IdP).

The SP hosts and protects the services that the user accesses. Remedy SSO is configured as an SP for BMC products. The IdP authenticates users and provides details of the authentication information to the SP. 

The following image shows the tasks that you need to perform to configure the SAMLv2 authentication in Remedy SSO.

Configuring the SAMLv2 authentication


Before you begin  


To configure the SAMLv2 authentication 

  1. (Optional) Select the Enable AR authentication for bypass check box to enable bypass URL to authenticate against AR. For more information about enabling BMC Remedy AR System authentication for bypass, see Enabling AR System authentication for bypass.
  2. Enter the SAML details. For more information on parameters, see SAMLv2 authentication parameters.


SAMLv2 authentication parameters

 FieldDescriptionApplicable versions
Identity Provider 
ImportOpens a dialog box to import the IdP metadata. You can provide a URL or specify a local file to import the data. 
IdPEntity IDIdP entity ID that is obtained from an external IdP provider such as AD FS or Okta.
Examples: http://adfs.local/adfs/services/trust , http://www.okta.com/exk4mi22tbfhiAnIn0h7
 
Login URLLogin URL of the IdP that is obtained from an external IdP provider such as AD FS or Okta.
Examples: https://adfs.local/adfs/ls , https://dev-726770.oktapreview.com/app/bmcdev726770_oktaidp_1/exk4mi22tbfhiAnIn0h7/sso/saml
 
Logout URL

URL provided by IdP to which the user is redirected for SP initiated logout.

If you do not provide any value in this parameter, then the value in the Login URL field is used for both login and logout endpoints.

9.1.02 and later
Logout Response URLURL provided by IdP to which the user is redirected for IdP initiated logout.9.1.02 and later
HTTP Binding Type

HTTP binding for SP initiated logout URL.

9.1.02 and later
IdPSigning CertificateSigning certificate that is used by Remedy SSO to sign requests that are sent to IdP. 
User ID AttributeUser ID attribute that is used to retrieve the user id from the specified attribute in the SAML response. If it is not specified, the NameID will be used as the user id. 
NameID Format

Defines the name identifier formats supported by the service provider. Name identifiers are a way for providers to communicate with each other regarding a user.

The Name ID format list is an ordered list, the first Name ID has the highest priority in determining the Name ID format to use. If the user does not specify a Name ID to use when initiating single sign-on, the first one in this list is chosen and supported by the remote Identity Provider.

A persistent identifier is saved to a particular user's data store entry as the value of two attributes. A transient identifier is temporary and no data will be written to the user's persistent data store.

Note: For linking user accounts from SP and IdP (Remote Identity Provider) together, after logging in,the persistent nameID format must be on the top of the list.

 
Auth Context CompareSelect an option (exact, minimum, maximum, better) from the list. 
Auth ContextAuthentication context that maps the SAMLv2-defined authentication context classes to the authentication level set for the user session for the service provider. 
Auth Issuer

Issuer details that are used by SAML authentication request XML to inform the IdP about the entity ID of the service provider for this request.

If the value is not specified, by default SP entity ID of the current realm will be used as Issuer in SAML authentication request.

 
Assertion Time SkewTime offset between Remedy SSO and IdP.9.1.02 and later
Assertion Time FormatTime format used by assertions.9.1.02 and later

Sign Request

Specifies whether the IdP requires authentication request to be signed.

 
Force AuthenticationThe option to select enforce authentication. 
Enable Single LogoutEnables SP initiated single logout, that is, if the user logs out from one application, the user gets logged out from all applications that share the same session.9.1.02 and later
Sign Response

Specifies whether Remedy SSO requires a signed response from the IdP.

Remedy SSO validates the signature from the authentication response.

 
Compress RequestSpecifies whether to compress the SAML message to save space in the URL. 
Service Provider 
View MetadataDisplays Remedy SSO metadata that is configured in the SP Metadata Template field. If any required parameter is not entered, the system shows an error message for that parameter. 
Template 
Authentication Request TemplateTemplate used for SAML authentication request. You can select Default or Custom and also edit the template if required. 
SP Metadata Template

Service provider metadata template. You can select Default or Custom and also edit the template if required.

If you are enabling the IdP initiated single logout feature, include the following information in the SP metadata template after the <AssertionConsumerService> tag and then update the settings of the IdP with the new metadata.

<SingleLogoutService Binding="urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST" Location="%%LOGOUT_REQUEST%%" ResponseLocation="%%LOGOUT_RESPONSE%%"/>

where,

  • Location: Endpoint for the IdP to send the logout request. For example https://access.bmc.com:8443/rsso/receiver/Saml.
  • ResponseLocation: Endpoint for the IdP to send logout response after getting the logout request from Remedy SSO. For example, https://access.xyz.com:8443/rsso/receiver/Saml.
 


Configuring AD FS as a SAML IdP provider 

After you configure Remedy SSO as an SP and AD FS as the remote identity provider in the Remedy SSO Admin Console, perform the following steps to configure AD FS to handle the SAML protocol:

  1. Import certificates
  2. Configure Relying Party Trust
  3. Modify the secure hash algorithm

  4. Configure claim rule

  5. Export AD FS certificates

Importing certificates 

Perform the following steps to import certificates: 

  1. Export the SSL certificate of the Tomcat on which the Remedy SSO is deployed.

     Click here to expand to read the steps to export the certificate.
    1. When you open the Remedy SSO URL, click on the padlock symbol in the address line of the browser.
    2. In the Certificate window, click on the Details tab.
    3. Click Copy to File.
    4. In the Certificate Export Wizard, click Next.
    5. In the displayed page, select "DER encoded binary X.509 (.CER)".
    6. Click Next.
    7. Provide a name for the file and include the path in the file name.

    Note

    The Common Name (CN) attribute of this certificate must be the same as the FQDN of the Remedy SSO server.

  2. Go to the AD FS server.
  3. Import the following certificates through the mmc console to the Trusted Root Certificate Authorities folder.

    • Import the SSL certificate of the Tomcat on which the Remedy SSO. You must establish an https connection between Remedy SSO and AD FS.

       Click here to read the steps to import the certificates.
      1. From the Run dialog box, type mmc to open Microsoft Management Console (MMC).
      2. Open the File menu and click Add/Remove Snap-in…
      3. Select Certificates from the list of available snap-ins and click Add.
        The Certificates snap-in dialog box is displayed.

      5. Open Personal>Certificates from the explorer panel.
      6. On the Action menu, point to All Tasks, and then click Import to start the Certificate Import Wizard.
      7. Import the SSL certificate of the Tomcat on which the Remedy SSO is deployed and the Signing certificate.
      8. Open Trusted Root Certification Authorities>Certificates from the explorer panel.
      9. Import the SSL certificate of the Tomcat on which the Remedy SSO is deployed.
    • Signing certificate (optional) - Remedy SSO may sign SAML messages. In such a case, the certificate for verifying such signature must be provided. This certificate must be stored in a *.jks file and path to it should be specified in the Remedy SSO Admin UI (General>Advanced>SAML Service Provider>Keystore File).

Configuring Relying Party Trust 

  1. On the AD FS server, open the AD FS 2.0 Management application.
  2. On Trust Relationships tab, click Relying Party Trusts.

  3. Click Add Relying Party Trust. A wizard appears.

  4. Configure the following parameters:
    1. Select Import data about the relying party published online or on a local network.

    2. Copy the metadata web link that you received from the Remedy SSO. For example, https://rssoexample.bmc.com:8443/rsso/getmetadata.jsp?tenantName= <name of the corresponding tenant>.

      Note

      If you see a warning, you can ignore it. However, if you are unable to proceed with the configuration, the certificates were not exchanged correctly. Contact the Remedy SSO administrator for more information.

      In case of specific network settings when AD FS and Remedy SSO servers are not able to connect using SSL protocol, this error message may be normal and can be ignored. In this case, you can import the SP metadata into AD FS offline using an XML file.
