 ssh Error: Connection closed by xxx [preauth]”

I had come across this issue once while doing the passwordless Authentication. It was hard to find  out the issue.  It was caused because my home directory which was a NFS mount, and selinux was causing this issue.

To fix this issue we need to run the following command as root.

setsebool -P use_nfs_home_dirs 1
