You can configure Data ONTAP to automatically schedule Windows Active Directory computer account password changes.
The duration is counted in weeks. The password change occurs randomly within the time period specified by the cifs.W2K_password_change_within option. The default for this option is off.
The default value is 4w, with a range of 1w through 8w. The password change is attempted at approximately 01:00 a.m. on the Sunday morning following the day when the configured time duration expires. The value in this option has no effect if the cifs.W2K_password_change option is set to off.
The default value is 1h, with a range of 1h through 6h. Attempts are made after the expiration of the configured W2K password change interval. The password change is attempted at a random interval between 01:00 a.m. and the time set by the cifs.W2K_password_change_within option.
In the following example, the storage system is configured for automatic domain computer account password changes using a 2-week interval and a 3-hour "change within" window:
system1>options cifs.W2K_password_change on system1>options cifs.W2K_password_change_interval 2w system1>options cifs.W2K_password_change_within 3h
