SSO (Shibboleth) with ZMS

Dear Community

We want to use a Singl-Sign-On service for ZMS. We have to use
Shibboleth as SSO Authentication/Authorization tool.

I only found information about a plone installation or about
deprecated guides (with FastCGI) for Zope but nothing for ZMS itself.

- Does someone made any experiences with ZMS and Shibboleth (or other
SSO services).

- And what about the PluggableAuthService? Could I use this to
implement a shibboleth plugin? If so, how can I use it (didn't find
much documentation).

Thanks in advance!
