There isn't really a one-size-fits-all solution. Where it is implemented in TC (MemoryRealm, and UDBRealm in 5.5.x), it authenticates against the Subject. In a lot of cases, you really only want the CN, or the CN+EMAIL fields. In other cases (e.g. JNDI, JAAS) you might want the entire cert. You can look through BZ for TC 4 to find several examples of proposed implementations. That said, patches are always welcome :). >The combination of these two things seems to me to really limit the >usefulness of client certificate authentication because authentication >provides little guarantee of who the client is, and even if it did, the >client is denied access to any protected resources. > This message is intended only for the use of the person(s) listed above as the intended recipient(s), and may contain information that is PRIVILEGED and CONFIDENTIAL.
