My understanding was that the customer already has issued roaming user
certs for his users. If that's the case these X.509 certs probably have
a common naming scheme. So you can find out which customer it was.

In a former customer project I made a similar concept for a
point-of-sale (POS) project with external partners hosting the POS
client machine. Your situation seems even easier because 1. your
customer's users already have certs and 2. you seem to have a web
application running.

Ciao, Michael.
