!!! Overview The [{$pagename}] is used to manage accounts in [Microsoft Active Directory] [{Image src='MMC Account Tab/MAD-user-Account-LDAP.jpg' caption='Account Tab' style='font-size: 120%; color: blue;'}] !! [userPrincipalName] (User logon name:) When using the [MMC], in the "New Object – user" dialog you are also required to specify a "User logon name". Which, in combination with the DNS domain name, becomes the "[userPrincipalName]". The [userPrincipalName] typically appears as jim@mad.willeke.com which is made up from the [MMC] interface value that is the "User logon name:" and the drop down that the [MMC] only allows the "@" and the domain name (mad.willeke.com). However, this is not enforced nor required. The [userPrincipalName] has no enforcement within [Microsoft Active Directory] other than the [MMC] interface. The [userPrincipalName] is one of the "logon" attributes permitted by [Microsoft Active Directory] Often, this value is populated with the user email address. The "[userPrincipalName]" is an alternative name for the user to logon with. This attribute is not always assigned a value in Active Directory. !! [SamAccountName] (User login name (pre-Windows 2000)): When you key in "User logon name", the field "pre-Windows 2000 logon name" is filled in for you with the first 20 characters of "User logon name". This becomes the "[SamAccountName]" attribute. [{Image src='MMC Account Tab/MAD-user-Account-LDAP-annotated.jpg' caption='Account Tab' style='font-size: 120%; color: blue;'}] !! Domain NetBios Name The Domain NetBios Name is not stored on the user but is shown as read-only in the [MMC Account Tab] This implies the user can logon as MAD\jim !! "User must change password" The [Microsoft Active Directory] LDAP attribute in [pwdLastSet|pwd-Last-Set attribute] determines if the user is prompted to change their password on the next login. !! "User cannot change password" Sets the [PASSWD_CANT_CHANGE] bit of the [user-Account-Control Attribute]. !! "Password never expires" Checking this value actually sets a [user-Account-Control Attribute] bit value [DONT_EXPIRE_PASSWORD] to indicate the password never expires. !! [Account Expires] When "Never" is check, then the [Microsoft Active Directory] LDAP attribute in [accountExpires] is set to 0, which implies the account never expires. We have also seen this value in transactions in [DirXML] as "[9223372036854775807|9,223,372,036,854,775,807]". !! "Store password using reversible encryption" Sets the [USE_DES_KEY_ONLY] bit of the [user-Account-Control Attribute]. !"End of:" When selecting a date, the value is set on the [Microsoft Active Directory] LDAP attribute in [accountExpires]. !!
