We are working with Citrix to get the v10 web client to use pass-through authentication to PS 4.5. Pass through works for 9.x client in our environment, but not v10. I've tried all fixes that I've found (create an uncompressed package, modify appsrv.src...etc. and repackage). Nothing has worked so far. I'll post the fix or method to accomplish this as soon as I hear back from Citrix if anyone is interested.
