Problem registering or updating behind an active SSL proxy service

SUSE Linux Enterprise Server 10
A proxy server is required or used to have access to the Internet.
The recommendations from the following TIDs have been followed but have not helped to resolve the issue:
If the proxy service cannot be bypassed, change the configuration of the proxy service software so that it does not alter traffic between the SUSE Linux Enterprise 10 system and the registration service (secure-www.novell.com) and the online update service (nu.novell.com and possibly the older update.novell.com).
If the proxy configuration cannot be changed, follow TID 3963765 - Manually importing a certificate into a Linux system.
In some network environments however, proxy software is used which actively scans (and, possibly, filters) the content of this type of connection; for example the Microdasys SCIP Encrypted Content Security software. As the TLS/SSL protocols have been designed to protect against eavesdropping, the only way in which such software can operate is by working with two traffic sessions: one between the client software and the proxy and one between the proxy and the server; the proxy software then decrypts and reencrypts traffic in both directions. The certificate used by the "server" end of the session between client and proxy service is then not the server's certificate but rather the proxy's. As the proxy's certificate is not signed by a Certificate Authority which is trusted by the client software in SLE10, the client software, assuming an attempted man-in-the-middle attack, will refuse to use this connection.
