Hans, Thaks for your help, my sshd_config options match yours, sshd_config doesnt recognises GSSAPIKeyExchange and GSSAPITrustDNS options. I continue to receive the "we sent a gssapi-with-mic packet, wait for reply" DEBUG message and the ssh tries password auth. i saw something related to krb5.keytab, do you know something about this file? thank you, marcello On Mon, Jan 4, 2010 at 3:01 PM, Hans van Zijst <hans@xxxxxxxxxxx> wrote: > Hi Marcello, > > A while ago I created the same construction that you want: ssh to a Linux > machine and login automatically with Kerberos.
