when i ssh to DOMAIN\user@localhosts-name authentication works fine through gssapi-with-mic:
debug3: remaining preferred: gssapi,publickey,keyboard-interactive,password
debug3: authmethod_is_enabled gssapi-with-mic
debug1: Next authentication method: gssapi-with-mic
debug2: we sent a gssapi-with-mic packet, wait for reply
debug3: Wrote 112 bytes for a total of 1255
debug1: Delegating credentials
debug3: Wrote 2816 bytes for a total of 4071
debug1: Delegating credentials
debug3: Wrote 80 bytes for a total of 4151
debug1: Authentication succeeded (gssapi-with-mic).
when I connect to a different machine It just seems to stop half way through the gssapi-with-mic authentication:
debug1: Next authentication method: gssapi-with-mic
debug2: we sent a gssapi-with-mic packet, wait for reply
debug3: Wrote 112 bytes for a total of 1255
debug1: Delegating credentials
debug3: Wrote 2816 bytes for a total of 4071 <----- ????
debug1: Authentications that can continue: publickey,gssapi-keyex,gssapi-with-mic,password,keyboard-interactive
How should I go about finding out what happened differently the second time. How can I find out if/why the auth was rejected by kerberos?
