Protecting Content

Access control in Shibboleth on IIS is done by modifying the shibboleth2.xml file in C:\opt\shibboleth-sp\etc\shibboleth. In that file you will find the definition for your host and add some access control rules.

Access control rules allow you to use Boolean logic to specify if a web resource is accessible based on what attributes are available. One of the attributes in our environment that is used in access control is “primary-affiliation”. It specifies if the user accessing the resource is either a “Staff”, “Student”, or “Guest”. For example, a rule to allow only “Staff” to access a resource the rule would look like this:

<AccessControl><Rule require="primary-affiliation">STAFF</Rule></AccessControl>

To protect content if the user is either a “Staff” or “Student” you would use this rule:

	<Rule require="primary-affiliation">STAFF</Rule>
	<Rule require="primary-affiliation">STUDENT</Rule>

To protect content on you website, you will need to do the following:

  1. Open up the shibboleth2.xml file located in C:\opt\shibboleth-sp\etc\shibboleth
  2. Look for a <RequestMapper> element in the shibboleth2.xml file. There should be a child element named <Host> that has an attribute named “name” that is your website’s name
  3. There should be a child element of <Host> named <Path> that has an attribute named “name” which corresponds with a url in your website that you want protected. By default that name is “secure”. Change the name to be a part of you web space that you want protected eg if you want to protect then the name attribute would be “payroll”
  4. Create a child element of <Path> named <AccessControl> which follows the syntax in the above section.
  5. Restart the shibboleth daemon
