Configuring Shibboleth for Zoom

[Mak, Steve]

Employee Unique ID: The unique ID for the user. Use this for simplifying the process when users change their email address.
We tried this and couldn't get it to work. We had hoped that setting EPPN (or something very stable) to the Employee Unique ID mapping would prevent issues with users suppressing or changing their email address and found that to be false.

I never had full admin access to the Zoom SSO settings so I never got a chance to look for a setting to "track email address changes at login", so I can't speak of its existence or efficacy.

We also did not do any NameID configuration changes for our side. We simply send transient ID for NameID. I don't recall seeing documentation that Zoom could use NameID for anything.

The primary account identifier for Zoom is whatever attribute you put in the Zoom Email Address in the SAML mapping.

Yes, but you can also have Zoom track email address changes at login.  From Zoom's help:

Employee Unique ID: The unique ID for the user. Use this for simplifying the process when users change their email address. If your unique ID is in the NameID element, enter <NameID> instead.

I don't think that this was configurable when we first started with Zoom, but I wouldn't swear to that either.  FWIW we map email address to the user's actual email address and Employee Unique ID to eduPersonUniqueID.

We've done extensive SSO testing with Zoom and this is what we found.

We had a school use email address and eduPersonTargetedID as a fallback and if our users suppressed their email address the user would be logged into a new account based on their EPTID. Those with EPTIDs could not be easily invited to meetings.

We've tried a combo of Zoom Email mapped to email and Zoom Employee Unique ID to EPPN/employeeNumber, but all that did was create a complex account identifier, where if either changed it resulted in an error or a new account.

What we've settled on is this: Zoom Email mapped to EPPN, and we deny release of email address to Zoom. This is the only choice we had due to a desire to cross integrate with Canvas and other EDU services.

Donald,

We have Shibb configured with the usual SAML persistent NameID, and Zoom configured to pay attention to eduPersonUniqueID as the user identifier, mail for email address etc.  The config has been in place since last spring term, and we haven't had any issues with logins or invitations.

Referring to this URL:


https://support.zoom.us/hc/en-us/articles/201363003-Getting-started-with-SSO


...it states the following:


First, configure your IdP to send us the following

  *   Any unique identifier linked to nameID such as eduPersonTargetedID, persistentID, or mail
  *   (Optional) Accepted attributes are email (urn:oid:0.9.2342.19200300. 100.1.3), sn (urn:oid:2.5.4.4), and givenName (urn:oid:2.5.4.42).


Our plan would be to configure Shibboleth to set the nameID for Zoom to not be a user's email address. We want to use a better unique & never changing attribute, the user's eduPersonUniqueId attribute value. We will also send Zoom a user's mail, givenname and sn attribute values.


Is anyone's Shibboleth configuration for Zoom using something other than email as the nameID value?  If so have you encountered any issues with nameID not set as a users email value? Especially with SSO login, the emailing of or accepting invitations or using the Canvas LTI Pro component.
