 * I have successfully been able to active on an individual sub-site, but when I
   try to activate in the network, i get the following error message:
 * > Plugin could not be activated because it triggered a fatal error.
 * I tried activating at the network level both before and after I activated it 
   on an individual site within the network successfully.
 * Would this be due to another network plugin conflict? Or something else I need
   to do to activate on the network level?
 * And thanks for developing this plugin. We had been using a much older and rudimentary
   CAS plugin at our University.

 * Hm, not sure! Can you dig up the specific error message so I can look into it?
   It should be in your web server’s error log. If you can’t find it, try using 
   one of the debug modes in WordPress to get access to the PHP error:

 * We’ve been having a problem getting the debug log to work. But I was able to 
   install ok on another network install with no problems.
 * Question. For the network settings, I’m trying to find a way to activate on all
   sub-sites automatically, but then adapt each site depending on unique needs. 
   Most would be standardized, but a few would need the ability to be customized.
   Is there a way to switch the network settings so that individual sites could 
   override the network settings or to bulk activate on all sites and have new site
   have the plugin activated (but still customizable)?

 * So the way Authorizer is currently built, if you Network Activate it, then you
   have the option of setting certain options at the network level that override
   any options of the individual sites. For example, at the network level you can
   set the auth backend (CAS, LDAP, or Google) that all sites use; you can list 
   individual users that will have access to all sites in the network; and you can
   set the authentication policy (public vs. private; allow all external users vs.
   allow specified external users).
 * That’s the opposite of what you’re thinking (individual sites override network
   settings), but I think you can make it work in your situation. Any thoughts?
 * Re: the install error, it might have been a conflict with another plugin, but
   without seeing specific error messages I’m not sure.

 * I’ll mark this as closed and open a new question about the second question.
