Leads from WebEx to Marketo via SSO?

[MariaMarketo]

There are three webinars for which we want to send a mailing out for. 

The webinars are held with "WebEx Event", which can be connected to Marketo via a LaunchPoint.

Now we do not have any explicit login data for WebEx Event, because the login is via SSO (Single Sign-on). How can we now establish the connection between Webex and Marketo?

+1 to Jay`s comment.

And just to add, a client is a Cisco partner and they kind of "have to" use Webex for webinars. Couple of months ago we tried with their engineering team to find a workaround to that issue, without success. Eventually they decided to set up a separate webex tenant, out of their primary domain, that does not have SSO. And this one works.

There are other threads on this in the community and the situation as of 2019 is that SSO is not supported in the launchpoint Webex connector
