[slurm-users] Add partition to existing user association

[Thekla Loizou]

Hi all,

I agree with both Marcus and Loris.

I am referring to modifying the association basically since when we 
first created our associations we had only "user" and "account" and now 
we also need to add the "partition".

My understanding from the documentation was that I would be able to 
modify the association and add the partition but it seems that this is 
not the case.

So I guess we will proceed with my original solution to delete all 
associations consisting of "user" and "account" and create new ones 
consisting of "user", "account" and "partition".

Regards,

Thekla
