I don't know if it's fixed now or not. The reason for that was in the US cryptography export regulations, and those have been improved in the last few years. In any case, even if it's not directly supported then probably a PAM module can still be written. Hm, considering the we'd like people to migrate from Linux to FreeBSD, having such a conversion script/program (especially if someone writes it for their own use anyway) in the base system would make a lot of sense. -SB
