Re: [HTCondor-users] How to add new users

[Steven C Timm <timm@xxxxxxxx>]

There are various ways to do it.  At Fermilab we have at various times required an x.509 certificate to submit and then had a mapfile of which certificates were allowed to submit, or htcondor also has the capacity to call out to an external server.  We are shifting to requiring "scitoken" access and having a mapfile of which scitokens

are allowed to submit and to which unix user they will be mapped.  Both of those techniques are so-called

remote submit where the users do not actually log into the submit host or have a shell on it, the condor_submit tool just contacts the remote schedd (access point) on its port.

There are a number of ways to configure the way htcondor recognizes its own users..you can have users that correspond to the unix usernames on the system or you can artificially make identities up that have nothing to do with the unix user names on the system, or you can run them all as "nobody".

Hi Cole,

How then do users get permission to submit jobs into the queue? Is it, if you have permission to be on the access point, you can submit?

I don't have any strict needs and have no firm opinions on the matter.

Here in Exeter, we are investigating using using ColdFront for our access management and they have a Slurm plugin <https://github.com/ubccr/coldfront/tree/master/coldfront/plugins/slurm>. And because HTCondor has such a nice Python API, I was going to see if I might be able to cobble together an equivalent plugin for this ecosystem.

But I couldn't find equivalent functionality, hence the question.

Cheers,
Matt

Hi Matthew,

At the moment condor does not have any tool or way of doing this. One could try to do some clever stuff with security and configuration but that can be long ,difficult, and isn't the same as just being able to allow or deny a user access to condor on an access point. However, this has been a topic of discussion with a design proposal in the works. So, if you have any strict needs and/or requirements regarding this don't be afraid to bring those to light for us.

Cheers,

Hi All,

I spend a decent portion of my time these days managing Slurm accounts
with https://slurm.schedmd.com/sacctmgr.html, but realized today that I
can't think of the equivalent tool the HTCondor ecosystem.

How exactly do new users get permission to submit jobs to the queue,
beyond being allowed on an Access Point?

Cheers,
Matt
