Description

see RITM0628588 from Willis

1. For CDF job submission by JobSub client, do not send
Kerberos tickets to worker nodes by DEFAULT.
- CDF now can use Fermilab public dCache scratch for
grid I/O.
- CDF is the only group with Kerberos tickets, so we
want to help to eliminate this operational burden.
- Without Kerberos security restrictions, CDF will work
on getting CDF Fermigrid jobs to work reliably at
INFN/CNAF -- this would be a benefit to all of
Fermilab if this Tier-1 site is opened up to
opportunistic Fermigrid use by all.

2. CDF needs a user transition period for the phaseout of
Kerberos.
- We request a low impact, interim CDF JobSub option,
like --sendtkt, to specify that tickets
() are made and sent to worker
nodes. (Probably good to have a JobSub server
switch that can disable it for good, post transition.)
- The CDF only --outLocation submission option, and
job segment ticket renewal (kinit -R) features are off
by default unless --sendtkt is requested.

3. Please renew CDF JobSub keytabs
- Final renewal, no more after transition period.
- CDF keytabs expired two weeks ago, giving this
Fermigrid job submission failure: 'user authorization
failure for CILogin DN' (Kerberos ticket creation
failure on server). INC000000898600 fixed this for 8
active users. Below is list a for 30 users (including the
8) who want to run jobs in the near future.
