I'm OK with this text. Typo: know => known in the last sentence.

> IKE is the preferred key management protocol for IPsec. It is used for

> negotiate authenticated keying material for use within those SAs. The

> and digital certificates) had several shortcomings related to use of IKEv1

> leverage the use of legacy authentication systems (e.g. RADIUS databases)
> to authenticate a remote user to a security gateway; and it could not be
> used to configure remote users with network addresses or other information
> needed in order to access the internal network.

> Two Internet Drafts were written to address these problems: Extended
> Authentication withn IKE (XAUTH) (draft-beaulieu-ike-xauth) and The ISAKMP
> Configuration Method (draft-dukes-ike-mode-cfg). These drafts did not
> progress to RFC status due to security flaws and other problems related to
> these solutions. However, many current IKEv1 implementations incorporate
> aspects of these solutions to facilitate remote user access to corporate
> VPNs. Since these solutions were not standardized, there is no assurance
> that the implementations adhere fully to the suggested solutions, or that
> one implementation can interoperate with others that claim to incorporate
> the same features. Furthermore, these solutions have know security issues.
> Thus, use of these solutions is not recommended, and these Internet Drafts
> are not specified in this roadmap.
