mschapp - MS-CHAP Password Change API
|
||
|
|
|
||
|
|
Abstract:
|
||
|
|
|
||
|
|
These APIs correspond to the MS-CHAP RFC -2433 sections 9 and 10. In order
|
||
|
|
to develop an MS-CHAP RAS server that works with an NT domain, these APIs
|
||
|
|
are required.
|
||
|
|
|
||
|
|
The MS-CHAP change password APIs are exposed through a DLL that is obtained
|
||
|
|
from PSS. This DLL is not distributed with NT4.0 or Win2000. It is up to
|
||
|
|
the ISV to install this with their product. The DLL name is MSCHAPP.DLL.
|
||
|
|
|
||
|
|
Only wide (Unicode) versions of these apis will be available. These are the
|
||
|
|
2 callable APIs:
|
||
|
|
|
||
|
|
* MSChapSrvChangePassword
|
||
|
|
* MsChapSrvChangePassword2
