Starting with ONTAP 9.3, you can configure Security Assertion Markup Language (SAML) authentication for web services. When SAML authentication is configured and enabled, users are authenticated by an external Identity Provider (IdP) instead of the directory service providers such as Active Directory and LDAP.
Before you begin
- You must have configured the IdP for SAML authentication.
- You must have the IdP URI.
Procedure
-
Create a SAML configuration so that ONTAP can access the IdP metadata: security saml-sp create -idp-uri
idp_uri -sp-host ontap_host_name
idp_uri is the FTP or HTTP address of the IdP host from where the IdP metadata can be downloaded.
ontap_host_name is the host name or IP address of the SAML service provider host, which in this case is the ONTAP system. By default, the IP address of the cluster-management LIF is used.
You can optionally provide the ONTAP server certificate information. By default, the ONTAP web server certificate information is used.
cluster_12::> security saml-sp create -idp-uri https://scspr0235321001.gdl.englab.netapp.com/idp/shibboleth -verify-metadata-server false
Warning: This restarts the web server. Any HTTP/S connections that are active
will be disrupted.

[Job 179] Job succeeded: Access the SAML SP metadata using the URL:
https://10.63.56.150/saml-sp/Metadata
Configure the IdP and Data ONTAP users for the same directory server domain to ensure that users are the same for different authentication methods. See the "security login show" command for the Data ONTAP user configuration.
The URL to access the ONTAP host metadata is displayed.
- From the IdP host, configure the IdP with the ONTAP host metadata.
For more information about configuring the IdP, see the IdP documentation.
- Enable SAML configuration: security saml-sp modify -is-enabled true
Any existing user that accesses the http or ontapi application is automatically configured for SAML authentication.
- If you want to create users for the http or ontapi application after SAML is configured, specify SAML as the authentication method for the new users.
- Create a login method for new users with SAML authentication: security login create -user-or-group-name user_name -application [http | ontapi] -authentication-method saml -vserver svm_name
cluster_12::> security login create -user-or-group-name admin1 -application http -authentication-method saml -vserver cluster_12
- Verify that the user entry is created: security login show
cluster_12::> security login show
Vserver: cluster_12
