I did an upgrade of Slurm this week (20.11 to 21.08.8) and while 
everything seems to be working with srun and sbatch commands, here is 
what I get when I try to launch jobs from drmaa library:

python: /usr/local/lib/slurm/auth_munge.so: Incompatible Slurm plugin 
version (21.08.8)
python: error: Couldn't load specified plugin name for auth/munge:

python: error: cannot create auth context for auth/munge

We are running CentOS7 and the following munge development libs are 
installed on all the nodes:


Here is the commands I used to compile slurm so I think the munge plugin 
was correctly built:

./configure --sysconfdir=/etc/slurm --enable-pam
make -j $(nproc)
make install

I don't know if this is a slurm or a drmaa bug. So any advice would be
