I need to use the GSSAPITrustDns
option to connect to a round robin service using Kerberos authentication. This works correctly using OpenSSH 5.3 and 6.6.1p1 on a selection of machines.
I have an Arch linux machine that has OpenSSH 6.7 and my ~/.ssh/config
is common between all these systems. Under OpenSSH 6.7 I get the following error on any usage of ssh:
~/.ssh/config: line 91: Bad configuration option: gssapitrustdns
~/.ssh/config: terminating, 1 bad configuration options
This prevents ssh from doing anything on that machine until I manually remove those lines. Of course that means Kerberos authentication doesn't work on that machine. I can't seem to find anything about this issue so I'm asking here before looking into it closer.
