SAML Integration

Overview

The Morpheus SAML identity source integration allows customers to add user SSO to Morpheus, authenticated by external login SAML providers.

To add a SAML integration:

  1. Navigate to Administration > Tenants

  2. Select a tenant.

There are 4 sections with fields that need to be populated depending on the desired configuration:

  • SAML Configuration

  • Role Mappings

  • Role Options

  • Assertion Attribute Mappings

SAML Configuration

LOGIN REDIRECT URL

This is the SAML endpoint Morpheus will redirect to when a user signs into Morpheus via SAML.

SAML LOGOUT REDIRECT URL

The url morpheus will post to when a SAML user log out of Morpheus to log out of the SAML provider as well.

INCLUDES SAML REQUEST PARAMETER

Yes (recommended) - the AuthN request will be sent via the ?SAMLRequest= parameter in the URL (GET)

No - the the AuthN request will be submitted in the body of the request (POST) .. NOTE:: The SAML SP documentation should mention which binding to use but GET is most common

SAML REQUEST

No Signature - No signature is used on the SAML request

Self Signed - A self-signed X.509 Certificate is gentered after clicking SAVE CHANGES. This signature value can be used by the SAML SP to verify the authenticity of the request

Custom RSA Signature - Import a custom RSA Private Key and respective X.509 Certificate. This signature value can be used by the SAML SP to verify the authenticity of the request

SAML RESPONSE

Do Not Validate Assertion Signature - The SAML response signature from the SAML SP will not be validated

Validate Assertion Signature - The SAML reponse signature from the SAML SP will be validated. Enter the SAML SP X.509 certificate in the Public Key field

Role Mappings

DEFAULT ROLE

Role any SAML user will be assigned by default

ROLE ATTRIBUTE NAME

The name of the attribute/assertion field that will map to Morpheus roles, such a MemberOf

REQUIRED ROLE ATTRIBUTE VALUE

Attribute/assertion value that a user must be assigned/a member of to be authorized, such as group or role in the SAML SP. This is obtained from the attribute/assertion defined in the ROLE ATTRIBUTE NAME field

<Morpheus ROLE NAME>

Additional roles that can be mapped to a user, which will add to the DEFAULT ROLE. Attribute value that a user must be assigned/a member of to be authorized, such as group or role in the SAML SP. This is obtained from the attribute/assertion defined in the ROLE ATTRIBUTE NAME field

Note

For more on Identity Source role mapping permissions, see the associated guide in our KnowledgeBase.

Role Options

ENABLE ROLE MAPPING PERMISSION

When selected, Tenant users with appropriate rights to view and edit Roles will have the ability to set role mapping for the Identity Source integration. This allows the Tenant user to edit only the role mappings without viewing or potentially editing the Identity Source configuration.

MANUAL ROLE ASSIGNMENT

When selected, administrators can manually edit Roles for users created through this identity source integration from the user detail page (Administration > Users > Selected user).

Assertion Attribute Mappings

GIVEN NAME ATTRIBUTE NAME

SAML SP field value to map to Morpheus user First Name

SURNAME ATTRIBUTE NAME

SAML SP field value to map to Morpheus user Last Name

EMAIL ATTRIBUTE

SAML SP field value to map to Morpheus user email address

Once populated, select SAVE CHANGES and the SAML identity source integration will be added.

In the Identity Sources section, important information for configuration of the SAML integration is provided. Use the SP ENTITY ID and SP ACS URL for configuration on the external login SAML provider side.

Note

In some cases, the SAML provider may need these values before providing the LOGIN REDIRECT URL and other values. When creating the integration, the NAME and LOGIN REDIRECT URL can contain any values, then selecting SAVE CHANGES will generate the above values. The NAME and LOGIN REDIRECT URL can be edited later, once the SAML configuration is created in the SAML provider.

  • ENTITY ID

  • SP ACS URL

  • LOGIN REDIRECT URL

  • SP METADATA

Note

Different SAML providers will have different field names and requirements. An Okta SAML Dev environment was used for the example integration in this article.

Okta SAML SSO

For Okta SAML integration, the following fields are mapped:

  • LOGIN REDIRECT URL : Identity Provider Single Sign-On URL

  • ENTITY ID: Audience URI (SP Entity ID)

  • SP ACS URL: Single sign on URL

Onelogin SAML SSO

For Onelogin SAML integration, the following fields are mapped:

  • LOGIN REDIRECT URL : SAML 2.0 Endpoint (HTTP)

  • SAML LOGOUT REDIRECT URL : SLO Endpoint (HTTP)

  • SIGNING PUBLIC KEY : X.509 Certificate

  • ENTITY ID: ACS (Consumer) URL Validator

  • SP ACS URL: ACS (Consumer) URL
