Anyone here successfully created an API gateway on an on-prem NetScaler (we are using AAD as IdP leveraging an Enterprise App registration using OAuth). A couple of us have been at this for a while with no luck so far. We can get an interactive login to AAD just fine, and then redirection back to server we are proxying too. That all works great. But vendor needs API gateway type authentication, sending bearer token/secret etc. If anyone has done this successfully would love to pick your brain. We found this, but not much else in the ways of examples to work from or documentation: https://docs.netscaler.com/en-us/citrix-adc/current-release/aaa-tm/authentication-methods/oauth-authentication/api-authentication-with-adc.html
