Invitations: ability to configure redirectUri

[awoimbee]

The invitation API allows requests without a redirectUri, but the default email template is broken: To accept or reject this invitation, click on the link below to log in. but there is no link.

It seems to me like:

• redirectUri should always be sent
• redirectUri should be configurable, either:
  • as an attribute
  • as a user input field when creating the invite

This change is necessary for #136 as magic link requires a redirect_uri.

Thanks. We add the ability to set this value in our Admin UI, and it would also be useful in the Admin Portal.

We don't have a great solution to "always" setting the redirectUri. Most people just customize their email template with their app link. We can't now make it required, as that would break backwards compatibility. However, I like your idea of storing a default as an organization attribute. We'd take that PR in keycloak-orgs
