Payflow Pro

Hello, I am using Payflow Pro as a payment processor on RedHat Linux and I need to be able to specify the cert directory so that we can process transactions. I can make things work with a shell script: --- #!/bin/sh PFPRO_CERT_PATH=/usr/local/ssl/certs;export PFPRO_CERT_PATH ./pfpro test-payflow.verisign.com 443 "TRXTYPE=S&TENDER=C&VENDOR=(ourvendorname)&PARTNER=(ourpartner)&USER=(ouruse rname) &PWD=(ourpassword)&ACCT=5105105105105100&ExpDate=1210&AMT=1.00" 10 -- and the test transaction works fine. However, when I use the payflow pro processing functions in PHP, I get the error: The response: Array ( [RESULT] => -31 [RESPMSG] => The certificate chain did not validate, no local certificate found ) The reason for this is that I need to set the cert path to go and look for the f73e89fd.0 file in my certs directory, and I don't know how to tell it to look for it. I've already tried setting the environment variable PFPRO_CERT_PATH=/usr/local/ssl/certs but that doesn't make a difference. It doesn't seem to be an option I can set in the config.h file for the payflow pro SDK that I downloaded. What's the deal? Anyone know how to fix this problem? Yes, I've RTM and STN already. Thanks Dan
