Vault signon OIDC with ADFS: How to see content of response from provider?

Hello,

I’m trying to have vault working with OIDC and Microsoft ADFS.
Following Azure Active Directory with OIDC Auth Method and External Groups | Vault | HashiCorp Developer I needed to leave groups_claims empty instead of groups in order to be able to sign in without permissions in vault (failed to fetch groups: “groups” claim not found in token). Even with group_claims=”roles” it failed.
verbose_oidc_logging is set to true and the audit_log has been enabled.

How can we see the detail of the response we receive from the OIDC provider ? I don’t see anything regarding this information in the logs or in the token detail (./vault token lookup token-dsfdsf…. )
The aim is to see what could be missing in the response I receive from the OIDC provider and see what can be used to map to.

Best Regards,

David
