Configuring NetApp ONTAP System Manager for SAML Authentication with VMware Identity Manager

======================================================================================

In this blog post, we will provide a quick walkthrough of configuring NetApp ONTAP System Manager to use VMware Identity Manager/Workspace ONE Access for SAML authentication. We will assume that your VMware Identity Manager and NetApp ONTAP System Manager environments are online and functional.

Step 1: Define User Accounts in NetApp ONTAP System Manager

——————————————————-

To begin, you must define user accounts in NetApp ONTAP System Manager to support your SAML users. If you are using existing user accounts, you will need to modify them. If you are using new user accounts, you will define them now. To do this, select the CLUSTER option from the left side of the NetApp ONTAP System Manager UI and choose Settings. Under the Security section, click the right arrow next to the Users and Roles section.

Step 2: Configure SAML IdP in VMware Identity Manager

———————————————-

Next, you will need to configure your SAML IdP in VMware Identity Manager. To do this, follow these steps:

a. Click the Catalog option from the left side of the VMware Identity Manager UI and choose New Application.

b. Enter a Name for your application (e.g., NetApp ONTAP System Manager), then click Next.

c. Under the Configuration portion of the wizard, paste the service provider metadata that you copied from the NetApp ONTAP System Manager UI into the URL/XML field, then click Next.

d. Scroll down and click on Advanced Properties. Ensure that the following options are enabled: Sign Response, Sign Assertion, and Include Assertion Signature. Set the Signature Algorithm to SHA256 with RSA and the Digest Algorithm to SHA256.

e. Click Next to continue.

f. On the Access Policies portion of the wizard, click the NEXT button to continue.

g. On the Summary portion of the wizard, click the Save and Assign button to save the definition and assign users who can access this new application.

Step 3: Configure SAML Authentication in NetApp ONTAP System Manager

———————————————————–

Now that your application configuration has been added to VMware Identity Manager, move back to the NetApp ONTAP System Manager interface and confirm that you have configured your SAML IdP and are ready to enable SAML authentication. Click the I have configured the IdP with the host URI or metadata checkbox, then click the Logout button.
