SAP Netweaver Business Client and a Citrix netscaler

Hi everyone,

As moderator, I received the following question from member Daniel Poole:

We're currently implementing the SAP NWBC for SRM. In order to load balance, and protect the SAP app servers, we're trying to pass traffic through a Citrix netscaler. However, we're encountering the following issues when punching out to external catalogues in SRM.

Using a URL via the Citrix Netscaler:

• A user logs into the NWBC using their SAP ID and password
• They click the link in SRM to a catalogue and they are prompted to enter their SAP ID and password for a second time

If we access the NWBC direct, i.e. bypassing the Citrix Netscaler, then the user only has to enter their ID and password when they log into the NWBC, there is no requirement for them to log in a second time.

I suspect it may be cookie related, but I have no idea where the issue is. Has anyone encountered this issue, or has any advice on how to solve it?
