I currently have an asp web application hosted in Azure that authenticates users with their e-mail address to verify that they belong to the company and then sending a confirmation code to that address. However, I am trying to integrate into the in-house login system and establish SSO using SAML. I have looked at multiple tutorials and have been working with the IT department to accomplish this, however I am at a standstill and don't know how to solve this problem. I am entirely new to SSO and SAML, so please bear with me.
The IT department asked for the metadata that my 'vendor' would provide. So after doing some research, I created an Access Control Namespace. I then provided IT with the metadata XML file that is available in the Access Control Namespace Management portal, which I assumed would be the correct metadata. However, they received an error 'No suitable connection found in the metadata for this type of connection' when they were trying to configure the SP connection. From what they've told me, they will configure things on their end from the metadata, then they will send me the metadata that is generated on their end. This all makes sense, but why is it not connecting on their end? I feel like I must be missing a big step. What do I need to integrate my application directly?
Any help and/or tutorials are greatly appreciated as I'm just learning how SSO and SAML works and am kind of lost at the moment as to where to go from here.
