The connection settings tab covers the metadata of the things you are connecting to and some information about your organisation. Other than the metadata, the fields are initially set by the wizard that ran when the administration console was first accessed after installation (probably by your IT team, covered on the Connect LA to your directory page).
The top section is about your organisation, whilst the bottom section is about metadata.
The name of this configuration. Only important if you have more than one configuration. If you change this, you will need to reattach any runtimes and change the name in the wizard too.
This needs to match the DNS record of your runtime - do not change one without updating the other.
The name of your organisation as it appears on the login page, and in your metadata. This one you can change without worry.
The entityID that will appear in your metadata. Once you have registered in any federations or passed details to service providers, changing this would require work on your part to provide those details to the federation and service providers.
If you are running LA as a live service, changing this could cause access problems for your users until all parties have made the update. It would also alter the identifiers service providers see for your users and any personalisation linked to their login would be lost.
Persistent user attribute
Defaults to the username attribute which itself is drawn from the username field specified in your authentication store settings. Any attribute from your datastore that uniquely identifies your users could be used.
If you are running LA as a live service, changing this will alter the identifiers service providers see for your users and any personalisation linked to their login would be lost.
This is where you add the metadata for any federations you are a member of. You can also add the metadata for individual providers that are not in a federation such as your VLE.
Use the plus button to add metadata. Several common federations are pre-configured. You can also manually specify an address:
Adding metadata will automatically download the metadata signing certificates and display details for you to accept or reject. In the case of a federation, they should provide a certificate fingerprint that you can check against these details. Once accepted, the certificate will be shown in the certificates section.
To remove metadata, tick the box next to the line or lines and click the red minus button.
When you make any changes, you will need to click the apply button at the top of the page to save them, then publish for them to take effect.
Displays all the metadata certificates that have been added. You can also add and remove them manually for times when federations change their certificates.
