Configure SAML

CSA as a service provider can be configured to support SAML (Security Assertion Markup Language) by configuring the Identity Provider endpoint.

SAML is configured in the Cloud Service Management Console.

SAML is used for Federated Identity Management to implement scalable, secure, Single Sign-On across organizations.

SAML Configuration on a CSA Fresh Install

Follow the below steps for SAML configuration on a CSA 4.7 Install:

1. Navigate to CSA_HOME/jboss-as/standalone/deployments/idm-service.war/WEB-INF/web.xml

   CSA_HOME is the directory in which CSA is installed.

   By default CSA_HOME is:

   Windows: C:\Program Files\HPE\CSA\

   Linux: /usr/local/hpe/csa/

2. Open web.xml file and uncomment the line:

   /WEB-INF/spring/applicationContext-saml.xml

3. Perform the following step (step 3) only in a HA Cluster environment on two or more CSA nodes:

   Open the file CSA_HOME/jboss-as/standalone/deployments/idm-service.war/WEB-INF/spring/applicationContext-saml.xml

   and uncomment the line

   <property name="entityBaseURL" value="http://localhost/idm-service"/>

   and replace with

   <property name="entityBaseURL" value="https://<fqdn>:<port>/idm-service"/>

4. Navigate to CSA_HOME/jboss-as/standalone/deployments/idm-service.war/WEB-INF/spring/applicationContext-security.xml

5. (Skip this step if HP SSO has been disabled manually.) Uncomment the segment between the lines:

   <!-- START SAML Web SSO with HP SSO --> and <!-- END SAML Web SSO with HP SSO -->:

   <!-- START SAML Web SSO with HP SSO -->

   <security:http pattern="/idm/v0/login" use-expressions="true" auto-config="false">
   <security:csrf disabled="true" />
   <security:custom-filter ref="requestTokenCompositeFilter" position="FIRST" />
   <security:custom-filter ref="hpssoProvidedFilter" before="PRE_AUTH_FILTER" />
   <security:custom-filter ref="hpssoIntegrationFilter" after="PRE_AUTH_FILTER" />
   <security:custom-filter ref="samlSsoFilter" before="CAS_FILTER" />
   <security:custom-filter ref="noPromptFilter" before="FORM_LOGIN_FILTER" />
   <security:http-basic />
   </security:http>
   <security:http pattern="/idm/v0/logout" use-expressions="true" auto-config="false">
   <security:csrf disabled="true" />

   <security:custom-filter ref="noPromptFilter" before="FORM_LOGIN_FILTER" />
   <security:http-basic />
   </security:http>

   <!-- END SAML Web SSO with HP SSO -->

6. (Skip this step if HP SSO has been disabled manually.) Comment out the segment below the line:

   <!-- START HP SSO ONLY Configuration -->:

   <!-- START HP SSO ONLY Configuration -->

   <security:http auto-config="false" pattern="/idm/v0/login" use-expressions="true">
   <security:csrf disabled="true"/>
   <security:custom-filter position="FIRST" ref="requestTokenCompositeFilter"/>
   <security:custom-filter before="PRE_AUTH_FILTER" ref="hpssoProvidedFilter"/>
   <security:custom-filter after="PRE_AUTH_FILTER" ref="hpssoIntegrationFilter"/>
   <security:custom-filter before="FORM_LOGIN_FILTER" ref="noPromptFilter"/>
   <security:http-basic/>
   </security:http>
   <security:http auto-config="false" pattern="/idm/v0/logout" use-expressions="true">
   <security:csrf disabled="true"/>
   <security:custom-filter position="FIRST" ref="requestTokenCompositeFilter"/>
   <security:custom-filter before="PRE_AUTH_FILTER" ref="hpssoProvidedFilter"/>
   <security:custom-filter after="PRE_AUTH_FILTER" ref="hpssoIntegrationFilter"/>
   <security:http-basic/>
   </security:http>

7. Restart the CSA service. See Restart CSA for instructions.

ADFS Group Claim Configuration

Pre-requisites:

Download CSA metadata and import to the ADFS machine.

This section contains two alternate ways to create a rule in Microsoft Server Manager to send group membership as a claim in Active Directory Federation Services (ADFS).

Rule creation method #1:

1. Open ADFS Management in the Server Manager.

2. In the console tree, navigate to ADFS >Trust Relationships.

3. Click Relying Party Trusts and select the trust where you will create the rule.

4. Right-click the trust and choose Edit Claim Rules.

5. In the Edit Claim Rules dialog, click Add Rule. The Add Transform Claim Rule Wizard is displayed.

6. In the Select Rule Template dialog, in the Claim rule template section, choose Send Claims Using a Custom Rule.

7. Enter a name for the rule.

8. In the Custom Rule box, enter the following rule syntax:

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

9. Click Finish to apply the changes.

Rule creation method #2:

Alternatively, you can add the rule using the following steps:

1. Open ADFS Management in the Server Manager.

2. In the console tree, navigate to ADFS >Trust Relationships.

3. Click Relying Party Trusts and select the trust where you will create the rule.

4. Right-click the trust party and choose Edit Claim Rules.

5. Click Add Rule. The Add Transform Claim Rule Wizard is displayed.

6. In the Select Rule Template dialog, in the Claim rule template section, select Send LDAP Attributes as Claims.

7. Enter a name for the rule.

8. Enter active directory in the attribute stores field.

9. For the LDAP attribute, select Token-Groups – Unqualified Names.

10. Create two rules.
    First rule, map samAccountName in LDAP Attribute (from the drop-down) to NameID in the Outgoing Claim Type.
    For second rule, for the outgoing claim type, specify any name but the same Outgoing Claim Type name should be used in the CSA SAML Configuration user interface under Attribute property.

11. Click Finish.

Exporting the ADFS Certificate and Importing the Certificate in Identity Management component

1. Go to certificates in the ADFS wizard. Select the option to Set Service Communications Certificate.

2. Select the certificate with 5 years validity (5 years is the default validity period; this comes up when you are configuring Certificate Services).

3. Select copy to file. Certificate import wizard will open. Leave the default settings and save it in CSA_HOME\jboss-as\standalone\deployments\idm-service.war\WEB-INF\classes\security.

4. Save the backup of samlKeystore.jks from CSA_HOME/jboss-as/standalone/deployments/idm-service.war/WEBINF/classes/security

5. Import the certificate of Identity Provider (IDP) to CSA_HOME/jboss-as/standalone/deployments/idm-service.war/WEB-INF/classes/security

   CSA_HOME is the directory in which CSA is installed.

   By default CSA_HOME is:

   Windows: C:\Program Files\HPE\CSA\

   Linux: /usr/local/hpe/csa/

6. Run the following command from the above directory path:

   keytool -import -alias adfs_alias -file your_certificate_name.cer -keystore samlKeystore.jks

7. Provide the Destination store Identity Management component password.

   Note nalle123 is the default password.

   Note Change the default password of samlKeystore.jks. After changing the password, update idm.saml.keystore.password in applicationContext.properties

Adding SAML Configuration for the Organization

1. In the Cloud Service Management Console, navigate to Organizations > Selected Organization > SAML.

2. In the SAML tab of the organization, provide the Identity Provider metadata URL in the SAML URL field. The Identity Provider metadata URL can be a web URL OR a relative directory path.

   • For example:

     Web URL for ADFS will be as shown in the format: https://<hostname>/FederationMetadata/2007-06/FederationMetadata.xml

     where <hostname> refers to the Identity Provider hostname.
     

   • For relative directory path, first create a metadata folder and then download metadata XML using the Identity Provider metadata URL and place the file to CSA_HOME/jboss-as/standalone/deployments/idm-service.war/WEB-INF/classes/metadata

     CSA_HOME is the directory in which CSA is installed.

     By default CSA_HOME is:

     Windows: C:\Program Files\HPE\CSA\

     Linux: /usr/local/hpe/csa/

     Restart the CSA service and set the SAML URL as: /metadata/FederationMetadata.xml,

     where FederationMetadata corresponds to the name of the metadata file.

3. The attribute name must be set to the name of Identity Provider attribute resolver.

   For Example: For ADFS, the attribute will be Outgoing Claim type of a Rule in the Relying Party Trust. For instance, Group.

4. Configure LDAP for your organization (select Organizations ->Selected Organization ->LDAP).

5. In the access control add the group.

   NOTE: Updating groups in access control is mandatory when groups are added before configuring SAML for an organization, irrespective whether it is fresh/upgrade setup.

   Note If CSA is configured for FIPS, see "Configure CSA to Use SAML" section in Cloud Service Automation FIPS 140-2 Compliance Configuration Guide for more information.

6. Download JCE Unlimited Strength Jurisdiction Policy Files from: http://www.oracle.com/technetwork/java/javase/downloads/jce8-download-2133166.html

7. Copy the local_policy.jar and US_export_policy.jar to jre/lib/security location.

   For Example: If CSA is using OpenJre, then the path must be CSA_HOME/openjre/lib/security/

   Windows: C:\Program Files\HPE\CSA\openjre\lib\security\

   Linux: /usr/local/hpe/csa/openjre/lib/security/.

SAML Configuration on a CSA Upgrade

To configure SAML when CSA is upgraded, complete the following steps:

1. Navigate to CSA_HOME/jboss-as/standalone/deployments/idm-service.war/WEB-INF/web.xml

   CSA_HOME is the directory in which CSA is installed.

   For example, CSA_HOME on Windows is C:\Program Files\HPE\CSA and on Linux is /usr/local/hpe/csa/

2. Open web.xml file and add new entry /WEB-INF/spring/applicationContext-saml.xml below the line

   /WEB-INF/spring/applicationContext-common.xml

3. Perform the following step (step 3) only in a HA Cluster environment on two or more CSA nodes:

   Open the file CSA_HOME/jboss-as/standalone/deployments/idm-service.war/WEB-INF/spring/applicationContext-saml.xml

   and add the line <property name="entityBaseURL" value="https://<fqdn>:<port>/idm-service"/> next to

   <!-- Filter automatically generates default SP metadata -->
   <bean id="metadataGeneratorFilter" class="org.springframework.security.saml.metadata.MetadataGeneratorFilter">
