Configure Identity service for token binding

Token binding embeds information from an external authentication mechanism, such as a Kerberos server or X.509 certificate, inside a token. By using token binding, a client can enforce the use of a specified external authentication mechanism with the token. This additional security mechanism ensures that if a token is stolen, for example, it is not usable without external authentication.

You configure the authentication types for a token binding in the keystone.conf file:

[token]
bind = kerberos

or

[token]
bind = x509

Currently kerberos and x509 are supported.

To enforce checking of token binding, set the enforce_token_bind option to one of these modes:

  • disabled

    Disables token bind checking.

  • permissive

    Enables bind checking. If a token is bound to an unknown authentication mechanism, the server ignores it. The default is this mode.

  • strict

    Enables bind checking. If a token is bound to an unknown authentication mechanism, the server rejects it.

  • required

    Enables bind checking. Requires use of at least authentication mechanism for tokens.

  • kerberos

    Enables bind checking. Requires use of kerberos as the authentication mechanism for tokens:

    [token]
enforce_token_bind = kerberos
  • x509

    Enables bind checking. Requires use of X.509 as the authentication mechanism for tokens:

    [token]
enforce_token_bind = x509
