[horde] issue with the attendees

[Francisco Ruiz]

I have horde installed on Cpanel and i am trying to make the calendar work
specificly for "Attendees" but i get an error when I add a contact that says
" Error retrieving free/busy information for...."

I was reading some forums and say that I should add something like

http://dominio.com/horde/kronolith/fb.php?c=user

on the: Freebusy URL field on the address book but first i don't know what
is excatly what i should write there and if that is going to make it work...

I hope you can help me out
