Il Servizio IDEM ha implementato un nuovo sistema di distribuzione dei metadata basato su MDQ che riduce drasticamente l'occupazione di memoria e i tempi di caricamento. Vedi https://mdx.idem.garr.it per le istruzioni di configurazione.

Aggregati di metadata

NOTA BENE: Gli aggregati di metadata sono da considerare deprecati e da utilizzare solo per sistemi che non supportano MDQ (vedi https://mdx.idem.garr.it).

IDEM Produzione: 

https://md.idem.garr.it/metadata/idem-metadata-sha256.xml

eduGAIN e IDEM Produzione: 

https://md.idem.garr.it/metadata/edugain2idem-metadata-sha256.xml

IDEM Test: 

https://md.idem.garr.it/metadata/idem-test-metadata-sha256.xml

Certificato

Tutti i flussi di metadata della Federazione IDEM sono firmati con il seguente certificato: 

https://md.idem.garr.it/certs/idem-signer-legacy.pem

1. Recuperare il certificato della Federazione:

2. Controllare la validità del certificato:

  • Eseguire il comando: openssl x509 -in /tmp/idem-signer-legacy.pem -fingerprint -sha1 -noout
    deve restituire: SHA1 Fingerprint=7F:62:60:A1:CE:2B:11:B8:D9:35:CF:7F:04:37:3E:81:5F:B4:DE:86

Istruzioni di configurazione

NOTA BENE: Gli aggregati di metadata sono da considerare deprecati e da utilizzare solo per sistemi che non supportano MDQ (vedi https://mdx.idem.garr.it).

Le istruzioni sono relative alla sola configurazione dei metadata, per guide complete sull'installazione e la configurazione di IdP e SP andare alla sezione Guide.

English version

The IDEM Service has implemented a new metadata distribution system based on the MDQ protocol that drastically reduces memory consumption and loading times. Check https://mdx.idem.garr.it for the configuration instructions.

Metadata aggregates

WARNING: Metadata aggregates are depreacted and to be used only for systems that do not support MDQ (check https://mdx.idem.garr.it).

IDEM Production: 

https://md.idem.garr.it/metadata/idem-metadata-sha256.xml

eduGAIN and IDEM Production: 

https://md.idem.garr.it/metadata/edugain2idem-metadata-sha256.xml

IDEM Test: 

https://md.idem.garr.it/metadata/idem-test-metadata-sha256.xml

Certificate

All the IDEM Federation metadata flows are signed with the following certificate: 

https://md.idem.garr.it/certs/idem-signer-legacy.pem

1. Download the Federation certificate:

  • wget https://md.idem.garr.it/certs/idem-signer-legacy.pem -O /tmp/idem-signer-legacy.pem

2. Verifiy the certificate:

  • Run the command: openssl x509 -in /tmp/idem-signer-legacy.pem -fingerprint -sha1 -noout expected value: SHA1 Fingerprint=7F:62:60:A1:CE:2B:11:B8:D9:35:CF:7F:04:37:3E:81:5F:B4:DE:86
