docs.sun.com site requires login name and passwd

hi all,

It appears that some pdf documents (specifically I tried some Sol9 admin
docs) on docs.sun.com site requires a login name and passwd in order to
download them. But there's no sign that these docs are password
protected and requires login. Any clue to download them?
