Cluster and Passwords
The BIAC cluster has a separate password from your BIAC Windows account.
-
Password requirements
Minimum length is 8 characters
Must contain at least 3 of the following character classes (uppercase, lowercase, digit, symbol)
Must be changed at least every 180 days (same interval as your BIAC Windows account)
Use the passwd
command on the head node (hugin) to change your cluster password.
If you try to change your password on one of the nodes, you will get the following error, because of the read-only filesystem that the cluster nodes use.
[petty@node23 ~]$ passwd
ReadOnly operating system, please change your password on the head node
passwords are automatically sync'd every 10 minutes
Once you've changed your password on the head node, there could be a slight delay before the new password takes effect for interactive sessions.
Passwords are automatically sync'd across all cluster nodes every 10 minutes. If you find that your new password doesn't work immediately, please continue to use the old password, or wait for the sync.
