Hi everyone.
I'm trying for a week to make my SP 2016 on Prem queryable with REST request from an external supplier.
The purpose for this supplier is to access a specific site and being able to read and retrieve new files in 2 libraries.
My configuration : I have the SP server, behind a IIS reverse proxy server.
What I did untill today :
- Created URL rewrite rule on reverse proxy's default web site ({REQUEST_METHOD} entry, ^OPTIONS$ template
- Set SPSecurityTokenService 's option ActivateOkResponseToCORSOptions to true
- Created Add-in with appregnew.aspx on the site
- Retrieved client_id, client_secret from this
- Went to appinv.aspx to set the wanted XML options to "/web"
- Retrieved the App Identifier
Today I don't know how to obtain a token for my supplier to succeed with his REST requests. I precise that I don't use (and don't want) any Azure things for the whole process, as I have my own AD.
From my side, my postman tests returns with 401 error.
From my supplier's side, he has a 90002 error (linked to... microsoft account accescontrol... Azure)
How can I make things to work (moreover without Azure)? Read lot and lot of docs, forums, but
Thanks to everyone for reading and helping.
Best regards.
