view history link does not work

hello users!
 
i do not know if this post is ok in this way, but i try it:
 
i have installed apache subersion on a linx system and all works fine,
only the view history link does not work

 
i made a lot of tests an noticed that in the upper side of tha page e.g.
e see only "/", but i my eyes i should see e.g. /foldername/...
 
and the if i click on "view history" there comes up an error, but i
think that the url behind the "view history" link is wrong.
if i check the url, under target i see e.g. only the last folder folder
and not the whole link.
 
e.g. target=//XNO_Aquaboost/ is only part of the folder, the beginning
is missing.
 
http://svnnat/repos-web/open/log/?base=&target=//XNO_Aquaboost/
<http://svnnat/repos-web/open/log/?base=&target=//XNO_Aquaboost/>
 
 
and then comey up this error:
 
Repository history
svn: PROPFIND request failed on '/svn/XNO_Aquaboost'
svn: PROPFIND of '/svn/XNO_Aquaboost': authorization failed
(http://svnnat <http://svnnat/> )
 
 
is this the right folder to post? and the right way?
any help is appreciatedt
 
br
