The current client installer works by copying the idp metadata to a static file. Now that the metadata is regenerated on the fly and has expiration times the installer should stop copying it and instead configure mod_auth_mellon with the URL where the IdP metadata is exposed so that it can automatically refresh the metadata as required.
This issue ticket was originally removed from the tracker as it clashed with the pull request. See upstream ticket for migration details.
