SSL according to RFC 2712. His comment is: This is a patch to openssl-SNAP-20010702 to support Kerberized SSL authentication. I'm expecting to have the full kssl-0.5 kit up on sourceforge by the end of the week. The full kit includes patches for mod-ssl, apache, and a few text clients. The sourceforge URL is http://sourceforge.net/projects/kssl/ . Thanks to a note from Simon Wilkinson I've replaced my KRB5 AP_REQ message with a real KerberosWrapper struct. I think this is fully RFC 2712 compliant now, including support for the optional authenticator field. I also added openssl-style ASN.1 macros for a few Kerberos structs; see crypto/krb5/ if you're interested.
