Livio Spring ffe9570776 fix(saml): improve error handling (#8928) ... # Which Problems Are Solved There are multiple issues with the metadata and error handling of SAML: - When providing a SAML metadata for an IdP, which cannot be processed, the error will only be noticed once a user tries to use the IdP. - Parsing for metadata with any other encoding than UTF-8 fails. - Metadata containing an enclosing EntitiesDescriptor around EntityDescriptor cannot be parsed. - Metadata's `validUntil` value is always set to 48 hours, which causes issues on external providers, if processed from a manual down/upload. - If a SAML response cannot be parsed, only a generic "Authentication failed" error is returned, the cause is hidden to the user and also to actions. # How the Problems Are Solved - Return parsing errors after create / update and retrieval of an IdP in the API. - Prevent the creation and update of an IdP in case of a parsing failure. - Added decoders for encodings other than UTF-8 (including ASCII, windows and ISO, [currently supported](efd25daf28/encoding/ianaindex/ianaindex.go (L156))) - Updated parsing to handle both `EntitiesDescriptor` and `EntityDescriptor` as root element - `validUntil` will automatically set to the certificate's expiration time - Unwrapped the hidden error to be returned. The Login UI will still only provide a mostly generic error, but action can now access the underlying error. # Additional Changes None # Additional Context reported by a customer		2024-12-03 10:38:28 +00:00
