I have a shared /home setup using Perceus Cluster Software (http://perceus.org) for our Cluster. Nodes are using CentOS 6.1 x86_64. /home is shared from the head to the nodes b
Following the advice below I checked /var/log/security on the node (host). It showed:
/var/log/security
fatal: Access denied for user user by PAM account configuration
I then edited /etc/ssh/sshd_config changing:
/etc/ssh/sshd_config
UsePAM yes
to
UsePAM no
Restarted the node and I can now perform password-less logins.
Thanks!
