Auth: error returned: 15029

Hello,
I am setting up a cluster with OpenPBS 20. I want the authentication to be handled by Munge. I installed Munge on all nodes and activated the service. Then I created a Munge key, copied it to all nodes (/etc/munge/munge.key), added the line PBS_AUTH_METHOD=MUNGE to /etc/pbs.conf on all nodes and restarted the nodes.

Now when I run qstat -a it gives me the following error:
# qstat -a
auth: error returned: 15029
auth: Failed to send auth request
No support for requested service.
qstat: cannot connect to server node01 (errno=15029)

Any idea what’s wrong?

Please check the /etc/pbs.conf file and see whether PBS_SUPPORTED_AUTH_METHOD=pwd
If not please set it and restart the pbs services.

It still doesn’t work. My head node acts as a compute node too. I have the following in /etc/pbs.conf:

PBS_SERVER= node01
PBS_START_SERVER=1
PBS_START_SCHED=1
PBS_START_COMM=1
PBS_START_MOM=1
PBS_EXEC=/opt/pbs
PBS_HOME=/var/spool/pbs
PBS_CORE_LIMIT=unlimited
PBS_SCP=/usr/bin/scp
PBS_LEAF_NAME=192.168.0.101
PBS_SUPPORTED_AUTH_METHOD=pwd
PBS_AUTH_METHOD=MUNGE

@dambuduk please set PBS_SUPPORTED_AUTH_METHODS=munge not pwd

With

PBS_SUPPORTED_AUTH_METHOD=munge
PBS_AUTH_METHOD=MUNGE

I get:
qstat -a
Connection refused
qstat: cannot connect to server node01 (errno=111)

@dambuduk Please change key name from PBS_SUPPORTED_AUTH_METHOD to PBS_SUPPORTED_AUTH_METHODS then restart pbs

Thank you @adarsh and @hirenvadalia ! Authentication with Munge works now.
