Hi,

this cluster is running on Debian 9, that said:

pcs 0.9.155;

from whatever node I try to do that I get the very same result;

the log is from SRVDRSW01, but it gets identical from every other node i 
tried on.

I tried to enter a wrong password for the hacluster user and, obviously, 
I get rejected because of a wrong username/password.

right after you can find the log when I deliberately entered a wrong 
password for the hacluster user:
