AIX: how to change a password as root without setting the ADMCHG flag

Try ssh -o PasswordAuthentication=yes -o PreferredAuthentications=keyboard-interactive,password -o PubkeyAuthentication=no host.example.org

In ssh v2, keyboard-interactive is another way to say "password". The -o PubkeyAuthentication=no option instructs the client not to attempt key pair authentication.

In addition, the PasswordAuthentication=yes option is to override any previously configured ssh options that may have disabled it.

Try this, i dont know if this will work fot you. its VB script

Dim UserName
Dim UserDomain
UserDomain = InputBox("Enter the user's login domain name")
UserName = InputBox("Enter the user's login name")
Set User = GetObject("WinNT://"& UserDomain &"/"& UserName &"",user)


Dim NewPassword
NewPassword = InputBox("Enter new password")
Call User.SetPassword(NewPassword)

If err.number = 0 Then
        Wscript.Echo "The password change was successful."
Else
        Wscript.Echo "The password change failed!"
End if
