If your proxy terminates SSL, you need the proxy's certificate as a trusted CA.
In order to have this, copy the PEM encoded certificate to /etc/ssl/certs and do a
Code:
c_rehash /etc/ssl/certs
on SLES11. On SLES12 you'd need to use the /etc/pki/trust/anchors directory and call
Code:
update-ca-certificates
See the
Code:
rpm -q --scripts openssl-certs
(SLES11) or
Code:
rpm -q --scripts ca-certificates
(SLES12) output if in doubt.
