Hi folks

Has anyone managed to successfully import into RACF a self-signed server 
certificate generated by Sterling Commerce's Windows-based "Certificate 
Wizard"? 

I've been sent one by one of our customers; they use it on their Windows-based 
C:D server, apparently quite successfully on their other C:D sessions from that 
server. However I can't import the certificate into RACF as a Certificate 
Signing Authority (CERTAUTH) as it issues message:

IRRD126I The certificate contains either a key usage or basic constraint 
extension indicating that it may not be used as a Certificate Authority 
certificate.  The certificate is not added.

This seems fairly reasonable since the attributes of the certificate only 
specify HANDSHAKE and DATAENCRYPT (not CERTAUTH), however, this is the standard 
for a self-signed server certificate coming out of the Certificate Wizard - in 
fact you can neither add nor remove attributes in this case.

I've tried importing it as a personal certificate for our C:D server, and it 
accepts that. I've tried putting it in the keyring as USAGE(PERSONAL), and 
USAGE(CERTAUTH) but either way C:D fails to negotiate the session, instead 
issuing message:

CSPA202E SSL handshake failure, reason=GSK_ERR_SELF_SIGNED 

I've had a call open for some time now with Sterling's support and although 
they're being very attentive and helpful, we're not managing to fix this, and 
the suggestion now is that we need to find out why RACF is not accepting the 
certificate, since Windows seems quite happy to do so.

Hopefully someone out there has done this (Windows C:D <-> z/OS C:D) 
successfully and can tell me where I'm going wrong?

Cheers

Brian
