I need to verify an ssl certificate chain with a certificate

The CApath option requires that the certificates be named uniquely based on a hash of their name, with a .0 extension.

Example:    1285dfe1.0

If you have all of the CA certs in a folder by themselves, you can use the following to rename them all:

for c in $(ll |awk -F" " '{ print $9 }'); do mv $c `openssl x509 -hash -noout -in $c`.0; done

So then you should have a folder full of correctly named CA certs. Example:

11cb4926.0
3c3c7119.0
67cbed36.0
7ace50d5.0
8bfc458a.0
eeb8b5c6.0

And now your openssl verify -CApath command should work.
