> The NMAS challenge response parts using a specific NMAS Method are also pretty nifty when used with the Vasco tokens (which I have played with but havn't managed to convince my management to deploy at my employer).  If you were in the mood it's pretty easy to setup and test using the Simple Password NMAS Method to confirm that the NMAS bits work too.

Yeah you're sort of wanting a simul function, I guess it'd be fairly easy to do.

Full accounting using LDAP is harder, and not really what LDAP directories are meant for :)
