vasd will automatically change the computer account's password to a new random value on a regular basis and regenerate the host.keytab file. This is done for security reasons and to mark the computer account in Active Directory as still active.
This password change is done every 30 days by default. This option controls how often the computer account's password is changed and the option value represents the change interval in days.
NOTE: This value is read once during vasd start-up. Any changes to this value require you to restart vasd before changes take effect.
The following example shows how to configure vasd to change the computer account's password every 5 days.
password-change-interval = 5
Also, there is a value of -1 that can be used like
password-change-interval = -1
It will change the password on restart, but will also set off a change every 30 seconds.
It is important to understand that this value is for testing purposes and should no be used in production.
You can manually trigger a password change using the following:
/opt/quest/bin/vastool -u host/ passwd -rk /etc/opt/quest/vas/host.keytab host/
