Hmm, I actually checked that 0.9.8 (the minimum version supported by 2.4) has SSL_OP_NO_TICKET. From the OpenSSL changelog: "Changes between 0.9.8e and 0.9.8f [11 Oct 2007] [...] If a client or server wishes to disable RFC4507 support then the option SSL_OP_NO_TICKET can be set." I expected distributions had incorporated that by now. Not sure whether to add extra code here, or just declare it ancient and let distros/users either backport newer OpenSSL or use 2.3. -Steffan
