@Mathieu yes indeed, I worked on this with @pierrebrunet PR https://github.com/vatesfr/xen-orchestra/pull/9042
Do you have any logs in xo-server service?

@Mathieu Hi, you need to be sure to have signed assertion and signed response because only one won't be enough.

We have updated the doc when you saw the impact. Sorry for the inconvenience:

Hello,

I've updated the cert with signed assertion and response

I also tried with a brand new certificate.

Unfortunately, login is still failing.

From xo-server:

And here is the plug-in configuration:

I'm not expert at all in SAML, sorry not being able to debug deeper.

@Mathieu Hello, can you show us your plugin configuration (without the certificate for security purpose) please?

Edit: thank you!

Mathieu

@pierrebrunet Just posted it above

@Mathieu Hi, do you use XO from source or do you have an XOA license? Just to know how to help you more confortably

Mathieu

@pierrebrunet
XO from source, commit 1ee07 from today.

closed fix(plugin/auth-saml): add default config in SAML #9093

@Mathieu Hi,
We merged the PR linked above with new options. If you have time, can you confirm it is working for you?
It will fix the audience error and let you choose if you want to sign responses and assertions.

@pierrebrunet
I'm jumping in here as well. Reporting that the PR fixes it for Google Workspace as well!
However, the checkbox in GW is called "Signed response".
No further adjustments of the plugin itself was needed.
