similar to: Incorrect description of GSSAPI vulnerability in 4.2 release note.

Hey all, perhaps someone might be able to shed a little light on this problem. Nothing I find in books and groups seem to address the problem. I'm trying to set up a series of connections with ssh that authenticate through GSSAPI. However, it seems that the credentials are not getting passed. >From the client.. debug1: Next authentication method: gssapi-with-mic debug2: we sent a

-----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

Hi all, I'm really struggling with getting Kerberos authentication to work between a FreeBSD host and a Linux host. I'm using the latest 6- STABLE code on the FreeBSD box, I've got forwardable Kerberos tokens (verified with "klist -f") and Kerberos and ssh are working fine in all other ways, but I can't get the Linux box to accept the Kerberos ticket as

Hi, This is to announce the availability of a new version of my GSSAPI key exchange patch for OpenSSH. The code is available from http://www.sxw.org.uk/computing/patches/openssh.html Changes since the last release are: *) Implement GSS group exchange *) Disable DNS canonicalization of the hostname passed to the GSSAPI library - an option is provided to allow this to be overriden on

Hello All, I noticed some different behaviour of GSSAPI Authentication mechanism in SSH and like to know the reasons for such behaviour. If I try GSSAPI auth for a user whose principal is not stored in KDC, the GSSAPI auth method is tried 2 times and it fails. If the user is stored in KDC and not having valid credentials, then SSHD tries GSSAPI one time and fails. The interesting part of

this is the proposed gssapi diff against OpenSSH-current (non-portable). note: if this goes in, the old krb5 auth (ssh.com compatible) will be removed. please comment. jakob Index: auth.h =================================================================== RCS file: /home/hack/jakob/mycvs/sshgss/auth.h,v retrieving revision 1.1.1.2 retrieving revision 1.3 diff -u -r1.1.1.2 -r1.3 --- auth.h

Hello, I'm trying to find clues on what may have changed for GSSAPI (Kerberos) authentication between OpenSSH 5.1p1 and 5.2p1. We have been using GSSAPI authentication for ssh for about 18 months with no problem with the OpenSSH build that is bundled with the FreeBSD operating system. All of those machines have OpenSSH 5.1p1. Last week I upgraded one of the servers to FreeBSD 8.0-BETA1

Will Simon Wilkinson's GSSAPI Key Exchange patch ever be incorporated into the OpenSSH source? http://www.sxw.org.uk/computing/patches/openssh.html I'm sure I'm not the only one that uses it and would like to see it become part of the OpenSSH source. Is there something missing or is there some technical/philosophical reason for not including it?

I can suggest a few things. krb5.conf ( if you use nfsv4 with kerberized mounts _ [libdefaults] ignore_k5login = true in But, it does not look like it in you logs your useing kerberized mounts. Im missing in SSHD_config : UseDNS yes And the defaults : # GSSAPI options GSSAPIAuthentication yes GSSAPICleanupCredentials yes Are sufficient for a normal ssh kerberized login. Optional,

Dear Sir and Madam: I'm writing to you on behalf of the MIT Kerberos team and several other parties interested in the availability of Kerberos authentication for the SSH protocol. We recently noticed that the OpenSSH developers had added support for the kerberos-2 at ssh.com user authentication mechanism. We are delighted but we believe additional steps are necessary, as explained

I think I had better update akk the kerberos and gssapi to the latest? Please advise.

Hi, thanks for your hints. DNS, /etc/resolf.conf, /ets/hosts seem to be correct. I'm able to do a kerberized ssh with a user from subdom2.subdom1.example.de (testuser at SUBDOM2.SUBDOM1.EXAMPLE.DE) But I'm not able to do the same with a user from example.de (user1 at EXAMPLE.DE). -- Regards, Andreas Am 01.11.2017 um 10:51 schrieb L.P.H. van Belle via samba: > I can suggest a few

An updated version of my patch for Kerberos v5 support is now available from http://www.sxw.org.uk/computing/patches/openssh-2.5.2p1-krb5.patch This patch includes updated Kerberos v5 support for protocol version 1, and also adds GSSAPI support for protocol version 2. Unlike the Kerberos v5 code (which will still not interoperate with ssh.com clients and servers), the GSSAPI support is based on

Hi, I am seeing a rather strange issue with openssh-5.3p1 (both client and server) under scientific linux 6. The systems in question are set up to authenticate against a Kerberos server. ssh'ing between machines works fine 99% of the time with the gssapi-with-mic method. But on occasion an ssh session will fail to spawn a sheel for the user after authentication. An example -vvv output in this
