The following errata report has been submitted for RFC6749,
"The OAuth 2.0 Authorization Framework".

--------------------------------------
You may review the report below and at:
https://www.rfc-editor.org/errata/eid6017

--------------------------------------
Type: Technical
Reported by: Michael Osipov <1983-01-06@gmx.net>

Section: 2.3.1

Original Text
-------------
Clients in possession of a client password MAY use the HTTP Basic
   authentication scheme as defined in [RFC2617] to authenticate with
   the authorization server.  The client identifier is encoded using the
   "application/x-www-form-urlencoded" encoding algorithm per
   Appendix B, and the encoded value is used as the username; the client
   password is encoded using the same algorithm and used as the
   password.

Corrected Text
--------------
Clients in possession of a client password MAY use the HTTP Basic
   authentication scheme as defined in [RFC7617] to authenticate with
   the authorization server.

Notes
-----
RFC 2617 has been superseded by RFC7617 which clearly defines in section 2.1 how a charset can be provided to solve the usecase described with encoding.

The original text of this RFC violates the approach described for Basic authentication.

Instructions:

This erratum is currently posted as "Reported". If necessary, please
