PHP 4.0.6 + VeriSign PayFlow Pro libpfpro 304

Hi all, I know the Payflow Pro thing has been done to death, but I've searched high and low for the answer to this last problem and I'm stumped. I know it's a simple thing somewhere, but I'm erroring out with the ssl/cert issue. To make matters worse, I'm definitely not a Linux expert. I'm using RH Linux 7.1 + Apache 1.3.19 (stock RPM, not recompiled) + PHP 4.0.6 (from Troels Arvin's site at rpms.arvin.dk) with the pfpro option compiled in, using version L304 of the pfpro SDK. My php.ini file has the "extension=pfpro.so" and "extension=libpfpro.so" lines added. I have the PFPRO_CERT_PATH environmental variable set and exported to all apps and it shows up with an env command. The test cert that came with the SDK is in the directory listed for PFPRO_CERT_PATH, along with a self-signed certificate. The perl cgi test script that came with the PF Pro SDK works, but our transaction.php page which just calls "pfpro_process($parameters, $host)" does not. I keep getting this error when processing a test transaction: The Response: Array ( [RESULT] => -8 [RESPMSG] => SSL failed to connect to host ) The Error: SSL failed to connect to host I occasionally get this slightly different error: The Response: Array ( [RESULT] => -31 [RESPMSG] => The certificate chain did not validate, no local certificate found ) The Error: The certificate chain did not validate, no local certificate found Any suggestions? I know this is connected to ssl and our cert files in some way--is it because we don't have a real VeriSign issued certificate on this machine yet, just the self-signed cert?
