Follow this guide to enable Zoom SSO with Shibboleth:
Single sign-on allows you to login using your company credentials. Zoom single sign-on (SSO) is based on SAML 2.0.
Zoom acts as the Service Provider (SP), and offers automatic user provisioning. You do not need to register as a user in Zoom. Once Zoom receives a SAML response from the Identity Provider (IdP), it checks if this user exists. If the user does not exist, Zoom creates a user account automatically with the received name ID.
Zoom can also work with other Service Providers such as PingOne, Okta, Centrify, Shibboleth, Gluu, and OneLogin. Zoom can also work with ADFS 2.0 SAML implementation.
First, login at https://zoom.us/account/sso. If you have a paid business or education account, you will see this option.
Second, you need to apply for a vanity URL for your company, like https://yourcompany.zoom.us.
Go to my Account and enter you desired vanity URL.
Third, configure your IdP to send us the following
Any unique identifier linked to nameID such as edupersonTargetedID, persistentID or mail (Optional) Accepted attributes such are email (urn:oid:0.9.2342.19200300.100.1.3), sn (urn:oid:18.104.22.168) and and givenName (urn:oid:22.214.171.124).
Lastly, enter your SSO information at https://zoom.us/account/sso. See the attached example from your idP xml metadata.
Sign-in page URL: <SingleSignOnService> Sign-out page URL: <SingleLogoutService> Certificate: <X509Certificate> * Note: Remove the Begin Certificate and End Certificate“ Issuer: <ID of EntityDescriptor> Binding: Choose http-post or http-redirect Default user type: Basic or Pro
Fourth, once configured, you can get the SP metadata XML file from : https://yourcompany.zoom.us/saml/metadata/sp
To start, all SSO users need to access https://yourcompany.zoom.us to login using a browser, or if you login from the desktop or mobile client, you need to enter domain name of your vanity URL under SSO login.
