This page and its child pages contains all documentation, deployment guides, instructions and manuals related to the service operations.

RESPONSIBLE: Information provided here is initially populated by the development team (during the transition phase), and revised based on the need or in a yearly service check by eduroam Managed IdP Service Manager.

Installation and Configuration

The generic installation and configuration instructions are publicly available at https://github.com/GEANT/CAT/blob/master/tutorials/Configuration.md

After following all these, some amount of fine-tuning in the config files is needed. Most items are self-explanatory; specific documentation to be added here for neuralgic spots.

eduroam Managed IdP Client Certificate Root CA

It is crucial to have a trust anchor for all issued client certificates which is stable on the long-term. To that end, an offline hardware-backed CA is provisioned and kept in a physically safe position in GEANT property. The CA itself is created with the CA generation script publicly available on GitHub.

The scripts require at least openssl 1.1.0.

IMPORTANT: adapt the settings/openssl-rsa.cnf and settings/openssl-ecdsa.cnf settings before issuing the CA. In particular:

crlDistributionPoints
caIssuers;URI.0
OCSP;URI.0

In the generation scripts themselves, change the following parameters:

CA.bootstrapnewRootCA: "randomsource" → /dev/hwrng as provided by the Raspberry Pi

need to point to the future URL of the CRL/OCSP Responder.

The script

CA.bootstrapNewRootCA

will generate TWO CAs, one with RSA/4096 bit keys, one with ECDSA/NIST P-521 keys. The latter one is future-proofing.

Afterwards, edit again settings/openssl-rsa.cnf and settings/openssl-ecdsa.cnf settings with new URLs for the intermediate (Issuing) CA.

Subsequently, issue the command

CA.generateNewIntermediateCA

Specific Instructions to make CAT instance a Managed IdP one

config-master.php → FUNCTIONALITY_LOCATIONS → CONFASSISTANT_RADIUS = "NONE"
config-master.php → FUNCTIONALITY_LOCATIONS → CONFASSISTANT_SILVERBULLET = "LOCAL"
generate and install all the per-NRO server cert CAs in config/SilverbulletServerCerts/*
generate and install the client cert issuing CA and corresponding (unprotected) private key in config/SilverbulletClientCerts/real.key and real.pem

Interplay of the eduroam Managed IdP system components

eduroam Managed IdP includes multiple components which need to interwork correctly for the service as a whole to work. The following external dependencies between the components exist

eduroam Managed IdP web frontend

issues OCSP statements for each of the certificates known to the system, using a cron job. See documentation on GitHub above. Make sure the cron job is running and verify that updated statements end up in the correct directory on the OCSP responder.

eduroam Managed IdP RADIUS Server

makes request at OCSP responder during every user authentication. Make sure the HTTP communication between RADIUS server and OCSP Responder is possible.
