[slurm-users] Slurmrestd unspecified errors.

[Heitor]

Hello,

So far I've been unable to use slurmrestd. I'm running CentOS7 with slurm
20.11.7 from the EPEL7 repo.

I generate a token this way:

$ sudo scontrol token username=ubuntu
SLURM_JWT=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJleHAiOjE2MjM2ODA2NjUsImlhdCI6MTYyMzY3ODg2NSwic3VuIjoidWJ1bnR1In0.bNIYye1YJ9jF15sJCljUhd6UQPlW1O9auxjMdUrAZ7M

(Should I use the token with or without the prefix "SLURM_JWT="? Or it does not matter?)

I then copy the entire string and use curl to make a GET request to the
ping endpoint:

curl --request GET "$host":6820/slurm/v0.0.36/ping \
	       --location --silent --show-error \
	       --header "X-SLURM-USER-NAME: ubuntu" \
	       --header "X-SLURM-USER-TOKEN: $token"

And I get a 401 return with the message "Authentication Failure".


Running slurmrestd with -vvvvv i can see these messages in the log:

What is this "unspecified error"?

I have the jwt auth plugin enabled in slurm.conf:

	AuthAltTypes=auth/jwt
	AuthAltParameters="jwt_key=/var/spool/slurmctld/jwt_hs256.key"

Munge is working and I can run jobs with srun/sbatch.

Am I missing something?


Cheers,
