Gets the Nullable DateTime that specifies the date and time that the account was locked out.
Assembly: System.DirectoryServices.AccountManagement (in System.DirectoryServices.AccountManagement.dll)
The underlying store does not support this property.
The account lockout time is system dependent, and cannot be set by the Account Management API. To unlock the account, use the UnlockAccount method.
It is possible that an account may not be locked out when the M:System.DirectoryServices.AccountManagement.AuthenticablePrincipal.AccountLockoutTime returns a non-null value. Applications should use the IsAccountLockedOut method to determine whether the account is locked out.
