Starting with CodeMeter version 6.90 CodeMeter reads out all existing Active Directory groups and users when CodeMeter is started. This cache is then regularly updated.

This interval is defined in profiling. You can set this interval to 1-1440 minutes or set it to a value of 0 to disable the queries completely.

To modify or disable the checkin interval:

  1. Open regedit
  2. Navigate to the key HKEY_LOCAL_MACHINE\SOFTWARE\WIBU-SYSTEMS\CodeMeter\Server\AccessControl
  3. Adjust the value of ActiveDirectoryUpdateInterval to the desired value in minutes
    Note: If the value does not yet exist, you must first create it with the DWORD type.
  4. Restart the CodeMeter service
