Yes, this is the case. The network infrastructure requires that any device touching the network be pre-registered, with enforcement implemented with the MAC address. If your MAC isn't registered you get placed into an isolated "rogue" VLAN.
Regardless of how the IPv6 address is configured, the MAC address doesn't change and is included in every packet sent from a host. Compare this with IPv4, where there's no mapping between IP & MAC addresses, unless specifically configured. So, if they're filtering on MAC address, then this shouldn't be an issue. I get the impression this may be caused by someone trying a bit to hard to control everything and not understanding the implications.
So, what am *I* (the user of a network) expected to do about it? Teach the network admins how they could have done it? I don't think you see the point, your Windows 7 example is the perfect counterexample. Windows 7 EXACTLY knows how to deal with this, automagically. It sets up both addresses, prefers the one obtained using privacy extensions, then, after a while when it notices there's no incoming global traffic, it falls back to the link local address. So the question here is, how to mimic that behaviour in 12.1, and *not* how to be an extra-smart egghead? The former will grant you access, the latter probably won't.
