Re: [HTCondor-users] mapfile, passing variables

[Rita <rmorgan466@xxxxxxxxx>]

I am pretty sure I need these,Âhttps://htcondor.readthedocs.io/en/latest/admin-manual/configuration-macros.html#AUTH_SSL_CLIENT_KEYFILE andÂhttps://htcondor.readthedocs.io/en/latest/admin-manual/configuration-macros.html#AUTH_SSL_CLIENT_CERTFILE

But these are system level knobs. There must be some environment variable I can tune to allow it to use user's cert and key.

Jaime,Â

Thanks for the response.Â

I don't want to use FS authentication because I plan to submit jobs to a remote scheduler. I have been SSL thru the tutorial numerous times and I got the hang of SSL authenticationÂso I want to stick to it. I am at the point where I can create a separateÂSSL certificate for a user. I already have a few. But, I am not sure how a user can say, "use this certificate"...

Letâs back up a step.

I assumed you already had separate SSL certificates for each of your users, which you wanted them to use to authenticate to HTCondor when submitting jobs. It sounds like that is not the situation, in which case I would recommend a different authentication method. If the users are logged into the machine running the condor_schedd, then the FS authentication method is ideal. It doesnât require any additional configuration.

If the users will be submitting jobs from a remote machine, then I recommend the IDTOKENS authentication method. You would create an IDToken for each user and place it in their home directory (under ~/.condor/tokens.d/). No configuration changes are required.

I can create multiple user certificates from a CSR. Such as this

openssl ca -config openssl.cnf -out zmiller.crt -infiles zmiller.req

I can inspect zmiller.crt. But how exactly do I use zmiller.crtÂ(its signed also)?Â

I am not following how a user can use their certificate. There is only 1 certificate for the pool. According to the tutorial (https://research.cs.wisc.edu/htcondor/CondorWeek2011/presentations/zmiller-ssl-tutorial.pdf), there is only 1 certificate.Â

In your example, you have onlyÂone user (jfrey). Do you have an example with multiple users?Â

The mapfile is how you tell HTCondor what user each SSL certificate should be mapped to. It can't define a $REMOTE_USER variable, as it doesnât have any information to determine a value.

You will probably have to add an entry in the mapfile for each userâs SSL certificate, providing the os account that certificate should be mapped to. Hereâs an example:

SSL "/DC=ch/DC=cern/OU=Organic Units/OU=Users/CN=jafrey/CN=647245/CN=James Freyâ jfrey

If your usersâ SSL DNs contain the os account name (e.g. if the DN include the userâs email address for your organization), you can use regular _expression_ rules to extract that and derive the os account name.
