HI!

I have a question about issuing SSL server certs for SGC (step-up
certs): 

Ralf Engelschall's presentation states that
extendedKeyUsage = msSGC,nsSGC
has to be set in the whole certificate chain.
(see http://www.modssl.org/docs/apachecon2001/slide-010-n.html)

Now I wonder if this is also required for the root CA cert.

Examining Verisign's certificate chain for a "Global Server ID"
(step-up certificate) reveals that an intermediate CA cert is used
which has extendedKeyUsage set with (2 16 840 1 113733 1 8 1) and (2
16 840 1 113730 4 1). (Found on
http://www.verisign.com/support/tlc/class3_install_docs/intermediate/v00g.html)

But the issuing root CA cert
OU=Class 3 Public Primary Certification Authority
O=VeriSign,Inc.
C=US 
seems to be a X.509v1 cert without any extensions (if I looked it up
correctly in Mozilla 0.9.2).

Any clue?

Ciao, Michael.
