--- Comment #1 from Juan Lang juan_lang@yahoo.com 2009-02-07 21:00:21 --- Not sure why this is getting assigned to Kai. Perhaps because he's the default assignee for secur32?
0x5a is SECPKG_ATTR_CONNECTION_INFO, and 0x53 is SECPKG_ATTR_REMOTE_CERT_CONTEXT. This latter one seems relevant, so I'm guessing you've got the correct component.
