• webapp

  • Contains the contents which will be included into the war. There must be at least one jar file contained inside webapp\WEB-INF\lib  and the jar files in that folder must implement exactly one service of type net.shibboleth.idp.plugin.IdPPlugin

• bootstrap

  • This folder:

    • MUST contain a file called plugin.properties.

      • This should be a property file with at least one property, "plugin.id".

      • The ID is used to locate the default truststore that verifies the GPG signature. The trust store will reside within a folder, named after the plugin ID, nested inside the IdP's credentials folder, e.g., idp.home/credentials/<pluginid>/truststore.asc

      • It must match the plugin ID that the plugin identifies itself with. By convention, plugin IDs are associated with the package name of the plugin to ensure uniqueness.

    • MAY contain a file called keys.txt  being the public key(s) used to sign the distribution. This enables the plugin installer to perform a one-time, "leap of faith" credentials check, and thereafter to prevent use of an unauthorized key.

• Packages ^5.2

  • This folder contains any other tar.gz or .zip files which the plugin installer will unpack. See below
