Hi all:
We encountered a strange bug when query job history using sacct. As show
below, we try to list user hpczbzt's job, and sacct do filter the right jobs
belong to this user. But there username is displayed as phywht.
> sacct -X --user=hpczbzt
--format=jobid%16,jobidraw,user,uid,partition,start,end,AllocCPUS,state%20
JobID JobIDRaw User UID Partition
Start End AllocCPUS State

The UID showed by sacct is right, and actual UID of phywht is 6272 as shown
below:
> id phywht
uid=6272(phywht) gid=6272(phywht) groups=6272(phywht)
> id hpczbzt
uid=6270(hpczbzt) gid=6270(hpczbzt) groups=6270(hpczbzt)
Those 2 system accounts are both stored in ldap. Also we have checked them
to be consistent on either slurmctld and slurmdbd node. What's more,
scontrol and squeue can show the right username as hpczbzt:
> scontrol show job 9884265
JobId=9884265 JobName=af_test_session
UserId=hpczbzt(6270) GroupId=hpczbzt(6270) MCS_label=N/A
Priority=519 Nice=0 Account=acct-phywht QOS=normal
JobState=RUNNING Reason=None Dependency=(null)
..
> squeue --user=hpczbzt
JOBID PARTITION NAME USER ST TIME NODES
NODELIST(REASON)
9884265 a100 af_test_ hpczbzt R 11:43:46 1 gpu04
9882328 dgx2 repeat_V hpczbzt R 7:07:56 1 vol05
..
So is there any guess about why only sacct display the wrong username?
