Routine Description:
This function changes the password for the specified user on
the list of servers. If we encounter a failure on changing
password for a particular server, we:
1) Send the new password over to the server to verify if it is
already the current password.
2) If not, return ERROR_INVALID_PASSWORD and the index into
the Servers array indicating the server which failed so that
we can prompt the user to enter an alternate old password.
When the password has been changed successfully on a server, we
notify the redirector so that the cached credential can be updated.
NOTE: All errors returned from this routine, except for the fatal
ERROR_NOT_ENOUGH_MEMORY error, indicates that the password
could not be changed on a particular server indexed by
LastProcessed. The client-side continues to call us with
the remaining list of servers.
If you add to this routine to return other fatal errors,
please make sure the client-side code aborts from calling
us with the rest of the servers on getting those errors.
Arguments:
Reserved - Must be NULL.
Return Value:
ERROR_BAD_NETPATH - Could not connect to the server indexed by
LastProcessed.
ERROR_BAD_USERNAME - The username could not be found on the server
indexed by LastProcessed.
ERROR_INVALID_PASSWORD - The change password operation failed on
the server indexed by LastProcessed.
ERROR_NOT_ENOUGH_MEMORY - Out of memory error. This fatal error
will terminate the client-side from trying to process password
change request on the remaining servers.
