This configuration parameter specifies the interval, in hours, for refreshing the credentials for prevalidated user and group accounts. The credentials for prevalidated users must be periodically refreshed to ensure they are in sync with Active Directory and that prevalidation will continue working after password changes.

The parameter value should be a positive integer. A value of 0 disables all prevalidation of users. For example, to refresh the credentials for prevalidated users every 8 hours:

adclient.prevalidate.interval: 8

In most cases, you set this configuration parameter using group policy.
