Re: [Condor-users] Condor losing stored credentials
It's just occurred again now. I looked immediately in SchedLog on the submit machine and found
this:
03/02 13:16:07 (pid:3940) Failed to log in
wibt@GHOSTVILLE with err=1311
Does anyone know what that error number
indicates?
thanks,
Hi
all,
I have a program
that produces condor jobs, waits for some to finish, inspects results and
produces more jobs until convergence of a statistic is reached. It sits in
the background and runs for weeks, keeping a cluster occupied until it's done,
which means it's running condor_submit about 5000 times per day (half-hour jobs,
100 slots).
The problem I'm
having is that occasionally, Condor will lose its stored credentials (we're
using windows auth but not run-as-owner) and cause condor_submit to fail.
Usually if I wait half an hour then run condor_store_cred add, all is good again
but obviously I can't do that in the middle of the night and I don't want it to
stop running overnight.
Sometimes,
condor_store_cred itself fails with a "Bad password" error, even though the
password is perfectly good. I've had a few situations where store_cred is
refusing to accept the correct password though authentication in general is
working on the rest of the network, i.e. I can login to machines,
etc.
Has anyone else seen
this problem or know of a solution?
Can someone tell me
the circumstances under which Condor decides to discard the stored
credentials? If there's some sort of transient issue with windows auth on
our domain, that might help me look for it. It looks like there is some
sort of transient thing going on where condor fails to authenticate, which (I
think) is the common cause for condor_submit to discard credentials and for
condor_store_cred to refuse to accept a new password. And it's only condor
that's having this problem.
(This is
7.4.2. I realise that there's now 7.4.4 released but getting an upgrade
past the Config Control Board is hard because this is on a classified
network. I can certainly do an upgrade though if this is a known bug that
has been fixed).
thanks,
