[slurm-users] GRES GPU issues

I'm running  slurmd version 18.08.0...

It seems that the system recognizes the GPUs after a slurmd restart. I
tuned debug to 5, restarted and then submitted job. Nothing get logged to
log file in local server...

So, I turned on debug to 5 in slurmcltd in master server, and after I
submitted my job, it shows...
[2018-12-03T12:02:10.355] _job_create: account 'lnicotra' has no
association for user 1498 using default account 'slt'
[2018-12-03T12:02:10.356] _slurm_rpc_submit_batch_job: Invalid Trackable
RESource (TRES) specification

So, we use LDAP for authentication and my UID is 1498, but I created a user
in slurm using my login name. The default account for all users is "slt"
Is this the cause of my problems?
root at panther02 slurm# getent passwd lnicotra
lnicotra:*:1498:1152:Lou Nicotra:/home/lnicotra:/bin/bash

If so, how is this resolved as we use multiple servers and there are no
local accounts for them?

Thanks!
Lou
