 ====== Cluster and Passwords ======
-  * The BIAC cluster has a separate password from your BIAC Windows account.
+  * The cluster uses DHE/EAD account credentials.
-  * If you do not already have an account, see [[biac:cluster:account|Requesting a Cluster Account]].
+  * Too many account failures can cause your EAD account to be locked.
-  * Use the ''**passwd**'' command to change your password.
+  * If you've forgotten your password, see [[biac:password|Account Passwords]].
-  * 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)
-  * You can only change your password on the head node (hugin), because of the read-only filesystem that the cluster nodes use.
-<code>
-[petty@node23 ~]$ passwd
-ReadOnly operating system, please change your password on the head node
-passwords are automatically sync'd every 10 minutes
-</code>
-  * Notice the error message pointing me to the head node
-  * Once you change your password on the head node there could be a slight delay in the new password taking effect for interactive sessions.
-  * Passwords are sync'd automatically across the cluster operating systems 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.
-  * If you've forgotten your password you can email [[mailto:help@biac.duke.edu|help@biac.duke.edu]] to request a reset.
