Hi, I have a multisite install where Im sharing content (nodes) , taxonomy and users. (I am only not sharing the following tables : menu, cache, variable, accesslog, watchdog) I present content to different websites based on tags (for example subdomain1.example.com will only present blogs tagged under vocabulary subdomain1 , similar functionality for subdomain2.example.com etc..cross tagged content will appear on both sites) The problem Im facing is with search...I want anonymous users on subdomain1.example.com to only see content tagged under subdomain1 while searching. Is there anyway to achieve this? I have installed TAC but setting permissions for anonymous users on a per site basis is not possible... Is there anything else I can be trying? There is a way to change 'anonymous' user per site on administer->settings...but that only seems to change the name Thanks, VJ
