This configuration parameter specifies the number of days the password hash for any user can be stored in the cache before it expires.

The parameter value must be a positive integer. A value of zero (0) specifies that the password hash should never expire. For example, to set this parameter so that the password hash expires after 7 days:

adclient.hash.expires: 7

If this parameter is not defined in the configuration file, its default value is 0.
