[ptp-user] "Auth fail" when attempting to open connections
|
Hello,
I've been enjoying the "synchronized project" functionality in PTP as it
is the only way I can productively use Eclipse to work on code bases
that need to be compiled and run on centrally-hosted servers. I've been
using it successfully for the last month or two.
However, in the last few days, I've all of a sudden started getting
"Auth fail" errors when I attempt to synchronize and/or open connections
that previously worked without incident. (The full error text from
<workspace>/.metadata/.log is pasted below this message.) This happens
basically every time and (unfortunately) renders Eclipse useless to me
again.
This is coincident with -- and maybe caused by -- a recent update to
Java that was pushed to me by my OS a few days ago: from OpenJDK 7u85 to
7u91.
Unfortunately "Auth fail" is so vague as to be of no help to me at all
in trying to diagnose what's actually wrong. Some details:
* OS: Ubuntu 14.04
* Java: (as noted above) OpenJDK 7, though I also tried Oracle Java
1.7.0_80 with the same results
* Connection: via SSH using Kerberos (gssapi-with-mic) authentication
Can anyone offer advice as to how I can try to track down what the
underlying problem is?
Thanks!
-Jeremy
