[Koha] About LINKS on URL ans Authorities

[rafael.antonio at sapo.pt]

Dear all,

I have installed KOHA 3.0 on a VMWARE virtual machine with Open Suze  
and large majority of modules are running O.K with UNIMARC flavour  
option.

The only problems has to see with KOHA links.
If we define a field 856$a as URL it is not allowed to run external  
links like www.google.com. System add site sufix http://... plus the  
value of the field on a ISBD and Normal View and work well using MARC  
view.
Must we change any system preference?
The same problem appears when we do a search on authorities. The list  
that is displayed would be used to select one entry for edit.  
Unfortunately the link does not work because autid is not added. Any  
hint?

Thanks,

Rafael
