Use this parameter to set the period of inactivity in minutes to automatically lock the protected keychain.
The default value is
0, which means the protected keychain is never automatically locked.
Refer to Lock protected keychain after number of minutes of inactivity for more information about the group policy that controls this parameter.
Note: Changing the group policy setting for this parameter does not change the parameter's value in this file. The two are set independently, with the group policy setting taking priority.
