The passphrase policy now applies to all users inheriting configuration from the selected object. You can change or disable it at any time.
Launch the Administrative Management utility (SLManager or MMC snap-ins).
Click Advanced Settings.
Select Use a passphrase policy.
Click Edit Policy.
In the Setting Description column, click the policy rule you want to edit, then in the Value column, specify the required value.
For example, if you think that users might find it easier to remember basic rules for all passphrases instead of remembering exactly how they typed a passphrase when they created it, you could require all passphrases to contain a minimum of 6 characters and a maximum of 12 characters. Set Minimum length to 6 and set Maximum length to 12.
By default, passphrase responses are required to contain a minimum of six characters. For security reasons, any passphrase policy you implement must also contain a minimum of six characters.
Click OK. The new values are added to the Value column.
