Hi Alex, Do you mean OAuth or OIDC? With Azure you'd want to be using OIDC which I think you folk have set up before with Azure? When it comes to the URIs you register, you'll want to use a * wildcard at the end of the OpacBaseURL, so that the users are able to login from any page in the Koha OPAC.

Context: We have a library (running Koha 22.11) that is trying to setup OAuth authentication with Azure. They have configured the Koha end using the new Koha 'Administration' > 'Identity provider' pages. When this library attempt a SSO login they get a 'AADSTS00113: No reply address is registered for the application' Azure error - see attached. Should the Redirect and Reply URIs in Azure just be the Koha OpacBaseURL (with https), or something else? Thanks so much, Alex
