By default standard users cannot delete other users jobs , only “root” user can delete other users jobs.  
If user1 and user2 are added as managers / operators then there is a possibility.

If you can share the output of the below commands

- qmgr -c ‘p s’ output
- cat /etc/sudoers | grep user
- qstat -Bf

Thank you for sharing the output, the configuration is correct and you are running 18.1.4 .  
If users are able to delete each other’s job by default, then it seems a bug to me. Please increase the log level , submit jobs as user1 , user2 , delete jobs as user1 and user2 , collect/upload the PBS logs and create a ticket.

It is worth performing an ruserok() test to see what the OS says about the users/systems involved. When checking to see if remote\_user1@remote\_host can delete local\_user2’s job, PBS will run the ruserok() system function (which consults hosts.equiv/rhosts, etc.) to allow/deny this. It can be tested with the following program run on the PBS server host:

```
/*
   Two use cases:
    1) User submitting job from remote host to server getting unexpected
        "Bad UID" message. That is, user doesn't have access when he thinks
        he should.
    2) User(s) can delete, etc other user(s) jobs. That is, one user is able
        to act as what he thinks is a different user, server sees them as
        being equivalent.

Build with "cc ruserok.c -o ruserok"

Usage (run on the PBS server system):

ruserok remote_host remote_user1 local_user2

where:

remote_host: the host from which the job is being submitted, or where the PBS client command is issued

remote_user1: the username of the user submitting the job, or issuing the client command

local_user2: the username of the user remote_user1 is trying to submit the job as, or owner of the job that remote_user1 is trying to act on with the client command
