Subject [users@httpd] Need Help: Reverse proxy and SSO
Date Fri, 18 Apr 2014 15:20:34 GMT
Dear Concern,

Not sure whether you are the right people to ask this question or not but if Yes, please help
us in below issue or else could you please forward it to concern person. We are trying to
setup SSO using Apache reverse proxy for Web Browser based application but getting error for
below URL (Flow is mentioned below), We are using latest Apache httpd and it's a reverse proxy
setup along with URL rewrite thingy.

Role and Auth wise, it's all fine. In addition to this, this page is working fine for the
user if we are hitting direct URL of NetWeaver Gateway (i.e. without Reverse Proxy URL); this
issue is occurring with Reverse Proxy URL only. The issue as below,
Remote Address: 10.52.62.72
Request URL: https://<Hostname>/sap/opu/odata/UI2/PAGE_BUILDER_PERS/Pages('%2FUI2%2FLAUNCH_PAGE')?expand=allCatalogs/Chips<https://%3cHostname%3e/sap/opu/odata/UI2/PAGE_BUILDER_PERS/Pages('%2FUI2%2FLAUNCH_PAGE')?expand=allCatalogs/Chips>
Request Method: Get
Status Code: 403 forbidden
Request Headersview source
Accept: application/json
Accept- Encoding:gzip;deflate,sdch
Accept-Language:en-US,en;q=0.8
Connection: keep-alive

Flow,

User--> Reverse Proxy --> SAP Portal (Authentication) --> SAP NetWeaver Gateway -->
SAP ECC (Backend)

Till authentication, it is working fine but after that I'm getting an error as below,

1. 2014-04-08 14:47:27 Error in OData response for GET

>From above, getting a feeling that its due to Encoding\ decoding issue but unable to get
