Does MINDIFF works on Solaris 6

Because the security enhancement for stringent password requirment, I want to enforce the OS

remember the previous ten password and does not allow repetedly using the same password.

However, I have heard that MINDIFF will be effective since solaris9, not sure about Solaris6

Does anyone can introduce his experience for MINDIFF? Thanks.
