I'm trying implement Shibboleth authentication on our DSpace 7.6, using
Google as the iDp.
I've got shibd running on Ubuntu 22.04, but when I download the Server
Metadata, I'm not getting a SP certificate (attached Metadata file).
I'm assuming that this a configuration issue, but the Shibboleth
documentation doesn't seem to be helpful on this point.

Controls session lifetimes, address checks, cookie handling, and the protocol handlers.
Each Application has an effectively unique handlerURL, which defaults to "/Shibboleth.sso"
and should be a relative path, with the SP computing the full value based on the virtual
host. Use of TLS is now assumed because browsers are enforcing it due to SameSite
restrictions. Note that while we default checkAddress to "false", this makes an assertion
stolen in transit easier for attackers to misuse.
