When does QAS update the local caches from Active Directory? -
说明
When does QAS update the local cache Unix/Linux from Active Directory when a change is made to a user or group
-
解决办法
The Unix attributes are updated via two methods.
1) By-name. When the user logs in or the system is asked about the user by name. This wil trigger an immediate update of their information so the latest is known.
2) Incremental. Using the USNChanged and highestCommittedUSN to get incremental updates from AD about information changes. This is triggered by system activity or on an inactive system by the lazy-cache-update-interval.

Here is infromation from the 4.1 vas.conf man page: lazy-cache-update-interval =Default value: 10 Please note default may differ for other versions, please refer to the man page for the version you ar on. In QAS 4.1, the default is every 10-20 minutes vasd will trigger an incremental update for user and group identity information. This only pulls down information for users and groups that have changed since the last incremental update. The value is in minutes, and the update will happen randomly somewhere between 1X and 2X the value set. This randomized interval is to reduce the load on the Domain Controller in situations where multiple computers are started simultaneously (such as after a power outage). [vasd] lazy-cache-update-interval = 15
