Drill authentication failing due to PAM

I have a small cluster (4 nodes), one of them used as a hybrid, where users log in to run queries. I have drill authentication enabled in the cluster.


For security, I am forcing new users to update their credentials when they log in. They do so successfully in the hybrid node but when Drill is ran, it fails and throws an error as "PAM failed to authenticate". I’ve temporarily corrected the error by updating the passwds manually in all the nodes, but this is just a short term solution.


Is there any guidance or materials on how to set up PAM centralized in single node and/or what to look for when prompted with this error?
