Hi Galaxy Admin list, 

This is my first post to this list.  Galaxy is a great tool and I am really enjoying working with it. 

Background, I am setting up a private galaxy instance for my company using AWS.  The installation is going very smoothly with a few problems listed below. I apologize if these questions have been asked before.  I have been through the documentation and searched the list pretty thoroughly and can't find the answers.  Thanks in advance for your help.

Question 1: Can't install tools in the tool shed

I have added this line to the universe_wsgi.ini

tool_config_file = tool_conf.xml,shed_tool_conf.xml

Which references a file that contains this tag:

<toolbox tool_path="../shed_tools">
</toolbox>

I have created this directory at the correct level and set permission to 755.

But I am still getting a non specific error loading tools.  
I saw that this was (is?) a known issue, but that it had been resolved in the latest build. What am I missing?
The log does not give me any more specific information about the error.

Any suggestions?

Question 2:  Weird log error.
 Every minute the log records this error:
galaxy.web.framework DEBUG 2013-03-07 13:07:42,207 Error: this request returned None from get_history(): http://127.0.0.1:8080/root
127.0.0.1 - - [07/Mar/2013:13:07:42 +0000] "GET /root HTTP/1.1" 200 - "-" "Python-urllib/2.6"
Is this a known issue?  How can I find more information about what is causing it?

Question 3:  Correct Settings:  My intent is to allow employees to access galaxy remotely without allowing public access.  In order to keep the data private, I have set:

require_login = True
allow_user_creation = False

Other than the id_secret setting (which I am currently researching) are there any big security holes I am missing with the default installation?

Thanks again for the help.
