!!! Overview 
[{$pagename}] ([LDAPDisplayName] [PwdLastSet]) represents the date and time that the password for this account was last changed. 

[{$pagename}] is functionally the same as the [PwdChangedTime] (__Except for the [LDAPSyntaxes]__) in many other [LDAP Server Implementations] as described within [Draft-behera-ldap-password-policy]
Many people can associate [{$pagename}] to the phrase from the [MMC Account Tab]: __User Must Change Password at Next Logon __

In [Microsoft Active Directory] the value is stored as a [LargeInteger]. If this value is set to 0 and the [User-Account-Control Attribute] does not contain the [DONT_EXPIRE_PASSWORD] flag, then the user must set the password at the next logon. 

When the administrator clicks the "User must change password at next logon" check-box in Active Directory [Users and Computers|MMC Account Tab], the [{$pagename}] ([PwdLastSet]) gets set to 0.

!Implementations 
* Windows 2000 Server 
* Windows Server 2003 
* ADAM 
* Windows Server 2003 R2 
* Windows Server 2008 [{$pagename}] is normally the same as [PwdChangedTime] in other [LDAP Server Implementations] as described within [Draft-behera-ldap-password-policy]!! Modifications to [{$pagename}] 
The only values that can be set are:
* 0 - To set "User Must Change Password at Next Logon", set the pwdLastSet attribute to zero (0). This is as if the [{$pagename}]=True - which is an implementation of [Password MUST Change] condition.
* -1 - setting the [{$pagename}] attribute to -1 which will effectively set the [{$pagename}] to the current time and remove the "User Must Change Password at Next Logon" restriction.
* The [{$pagename}] attribute cannot be set to any other values except by the system. 

![MMC Account Tab] 
The values for this can be set within the [MMC] on the [MMC Account Tab] as: __User Must Change Password at Next Logon __.
