Read about the big picture in Security 2.3 Howto.

In the following examples we assume you use jspwiki.applicationName = JSPWiki in your jspwiki.properties.

Groups

To assign privileges to a wiki group in 2.4 edit jspwiki.policy like this:

grant signedBy "jspwiki",
  principal com.ecyrd.jspwiki.auth.GroupPrincipal "Admin" {
    permission com.ecyrd.jspwiki.auth.permissions.AllPermission "JSPWiki";
};

You can use any other permission like in the other examples in the same file. AllPermission is pretty much for normal groups.

Single Users

To assign privileges to a wiki user in 2.4 edit jspwiki.policy like this:

grant signedBy "jspwiki",
  principal com.ecyrd.jspwiki.auth.WikiPrincipal "John Doe" {
    permission com.ecyrd.jspwiki.auth.permissions.AllPermission "JSPWiki";
};

Replace John Doe with the full name of the wiki user to assign privileges to.

After editing jspwiki.policy

After you are done editing don't forget to restart Tomcat to make the changes work.
