In our computer cluster we have several machines with the submit role, as some users prefer to use different specific machines to send their jobs. I would like to change this to only having one submit machine in the cluster but making it transparent to users so that they all can still submit jobs from any machine.
When trying to use the "condor_submit" command with the "-name" option in order to specify the address of the submit machine, I get the following error:
Submitting job(s)I set up the cluster using the "get_htcondor" tool, so I do not know a lot about the authentication method set up during installation, but I guess it is the default one.
ERROR: Failed to connect to queue manager <ommitted for privacy>
AUTHENTICATE:1003:Failed to authenticate with any method
AUTHENTICATE:1004:Failed to authenticate using FS
AUTHENTICATE:1004:Failed to authenticate using IDTOKENS
I read the Security section in the documentation and found the
"File System Remote Authentication" method (https://htcondor.readthedocs.io/en/latest/admin-manual/security.html?highlight=remote%20file%20system%20authentication#file-system-remote-authentication),
which is perfect for our cluster, as all machines share a common
/home directory and a LDAP central authentication is set up. I
just create a "/home/condor-authenticate" folder with the common
user group as owner and set up write permissions for the group.
I tried to configure HTCondor by adding the following lines to the end of the condor_config file:
FS_REMOTE_DIR = /home/condor-authenticateand then running "condor_reconfig". However, when I then check with "condor_config_val" the values of these variables, FS_REMOTE_DIR is correctly set but SEC_DEFAULT_AUTHENTICATION_METHODSÂ still shows its previous value ("IDTOKENS, FS") and sure enough, I still get the same error as before.
SEC_DEFAULT_AUTHENTICATION_METHODS = FS_REMOTE, IDTOKENS, FS
What am I doing wrong? Should I set these variables elsewhere? Do I need to restart the local condor_master to change this?
I'm using HTCondor version 9.5.0
