Can someone explain the rationale of making Windows Single Sign On
(SSO) incompatible with Tru64's Enhanced (C2)Security? Unless I'm
missing something this would make it easier for Windows users to get
onto a Tru64 machine. Once there they'd find an old fashioned "crypt"
encrypted root password just begging to be cracked. Does anyone know
a way to use SSO with Enhanced Security? (If there isn't a way then I
can't use it.)
