Hi Jon,
Did you check the software prerequisite minimum versions listed in this
page: https://slurm.schedmd.com/rest_quickstart.html#prereq
IHTH,

Hi,
I feel like I must have missed something obvious here, so hopefully
someone can spot it! We recently updated to Slurm 24.11.6 on our cluster
and I made sure to compile --with slurmrestd and --with jwt, as there
are a few things I've been meaning to try out with the REST API.

And indeed I get a slurmrestd package out of it, which I've successfully
installed with no errors. I've created a JWT key and rolled it out to
the controller node, but when I go to check auth types I get:
slurmrestd -a rest_auth/jwt
slurmrestd: fatal: Unable to find plugin: rest_auth/jwt
Running an strace on this process shows that it does in fact stat
the .so that does in fact exist:
stat("/usr/lib64/slurm/auth_jwt.so", {st_mode=S_IFREG|0755,
st_size=283728, ...}) = 0
And I'm kind of stumped now. I've checked through all the resolved bug
tickets to see if I can spot what is wrong but I'm getting nothing, and
I can't find anything in the mailing lists either, other than things
I've checked. Has anyone else had similar issues, or can someone see the
blindingly obvious thing I'm missing?
