Embedded GW on ECC, multiple clients, authenticates to incorrect client(?)

Hi guys,

Need some help please with the config of gateway as a local embedded component on the ECC stack, where we have multiple clients.

The issue we're facing is that even if i explicitly address the origin alias or even SID/Client the URL, when we try to login, it's asking for authentication to the wrong client.  We're very new to gateway and this is a proof of concept build we're working on.

Below are the SID's / clients we're working with.

So now if i call the following URL:

<hostname>:8000/sap/opu/odata/sap/ZSOP_STORE_INVENTORY_SRV;o=sid(ERZ.301)/STORE_MASTERSet(Site='1368')?$format=json

I get presented with this following basic authentication request, asking for ERZ 201 and not ERZ 301 as per the origin in the URL.

We've tried a number of things but no joy unfortunately, we're not entirely sure if the way we've set the config is the best approach for this type of installation.

Any help would be greatly appreciated!

Many thanks,

Dave
