AI Summary: The task is to debug an OAuth2 authentication failure in the free5GC open-source 5G core network. The authentication fails when using certificates generated by OpenBao (a HashiCorp Vault fork), but works with pre-generated certificates. The problem appears to be related to certificate verification, and requires investigation of the certificate generation process, the free5GC configuration (NRF and AUSF), and the OAuth2 implementation within the free5GC components. Debugging will involve analyzing logs, configuration files, and potentially inspecting the certificate chain.
