Because IBM Security Access Manager 7.0 is no longer in service (ie. it is EOS) the IBM Knowledge Center documentation has been removed. You may be able to find copies of the documentation elsewhere on the internet in places such as https://authorzilla.com.
Was there a particular pdf that you were looking for as the majority of the documentation provided with IBM Security Access Manager 8.0 and 9.0 is still applicable to 7.0?
