memcached and TLS resumption
Hi all, I’m trying to use memcached to do TLS session resumption. (FreeRad 3.2.1, Debian 11) What works: * eap-tls authentication (with OCSP) * tls session resumption works with a local cache – entries are created and then referenced correctly (if I define persist_dir in eap/cache) * I see an connections to (local) memcached daemon initialising at FreeRad startup But nothing gets written to Memcached. I’ve tried adding driver = “rlm_cache_memcached” to eap/cache (freeradius -Xxx says its unused). It looks to me like the standard rlm_cache and the eap/cache are unrelated – is this correct? (and then there is cache_eap…). Any pointers as to what I am missing here would be great. Thanks, Jim (And so a plan B - if I were to use a shared NFS filesystem for the cache directory, would that be a disaster?)

I’m trying to use memcached to do TLS session resumption. (FreeRad 3.2.1, Debian 11)
Unfortunately, v3.2 doesn't support that.
What works:
* eap-tls authentication (with OCSP) * tls session resumption works with a local cache – entries are created and then referenced correctly (if I define persist_dir in eap/cache) * I see an connections to (local) memcached daemon initialising at FreeRad startup
But nothing gets written to Memcached. I’ve tried adding driver = “rlm_cache_memcached” to eap/cache (freeradius -Xxx says its unused).
Generally if it's not documented as working, then it doesn't work.
It looks to me like the standard rlm_cache and the eap/cache are unrelated – is this correct?
Yes,
(and then there is cache_eap…). Any pointers as to what I am missing here would be great.
We're making the EAP cache generic in v4, and it will support any method for caching the EAP data. But v4 is still at least a few weeks off :( Alan DeKok.
Hi Alan, Ok, thanks for letting me know, I'll wait for v4 then. Do you have an opinion on the merits of other approaches to use TLS session caches in a cluster? (NFS, rsync, ??)

I'd prefer rsync to NFS. If NFS goes away, the OS might *lock* the RADIUS process until NFS comes back. That's bad. :( If the cache entries last a day, then it's pretty simply to rsync the directory periodically from one system to another. Alan DeKok.
