-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi,
I'm pleased to (finally) announce the availability of my GSSAPI Key Exchange patch for OpenSSH 4.7p1. Whilst OpenSSH contains support for doing GSSAPI user authentication, this only allows the underlying security mechanism to authenticate the user to the server, and continues to use SSH host keys to authenticate the server to the user. For many sites who already have security infrastructures such as Kerberos deployed, managing large numbers of SSH host keys is an additional, unneccessary, burden. GSSAPI key exchange allows the use of security mechanisms such as Kerberos to authenticate the server to the user, removing the need for trusted ssh host keys, and allowing the use of a single security architecture. This patch adds support for the RFC4462 GSSAPI key exchange mechanisms to OpenSSH, along with adding some additional features to the GSSAPI code that is already in the tree. The patch implements: *) gss-group1-sha1-*, gss-group14-sha1-* and gss-gex-sha1-* key exchange mechanisms. (#1242) *) Support for the null host key type (#1242) *) Support for CCAPI credentials caches on Mac OS X (#1245) *) Support for better error handling when an authentication exchange fails due to server misconfiguration (#1244) *) Support for GSSAPI connections to hosts behind a round-robin load balancer (#1008) *) Support for GSSAPI connections to multi-homed hosts, where each interface has a unique name (#928) (bugzilla.mindrot.org bug numbers are in brackets) There are no code changes since the previous release. As usual, the code is available from http://www.sxw.org.uk/computing/patches/openssh.html I'm also interesting in hearing from people who might be interested in testing some new cascading credentials delegation code. When you renew your Kerberos credentials on the client, this code will automatically propagate these renewed credentials to the server, allowing the seamless renewal of credentials across ssh sessions distributed across many different machines. If you have an interest in testing this code in a non-production environment, please let me know! Cheers, Simon. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (Darwin) iD8DBQFG/CG9qWndc26pXmcRAikbAKDLw84hjqy2Z4dF6/H4ZmK6/gY4XwCffEWm FQleDwIuPJI8sJQ/I9SSRDo= =RJHh -----END PGP SIGNATURE----- ________________________________________________ Kerberos mailing list [email protected] https://mailman.mit.edu/mailman/listinfo/kerberos
