Issues with rlm_cache_memcached in 3.0.7

13 Apr 2015

      Hello,

I'm trying to get rlm_cache_memcached working, but I'm having some
issues with freeradius merging the values from memcached - all my
values get truncated.  Am I doing it wrong or is this a bug?

I've attached the full output of radiusd -X, but I've pasted
relevant sections below.

Creating the cache entry:

Reading and merging from the cache:

    (1)       update control {     
    (1)         &Cache-Read-Only = yes
    (1)         &Cache-Merge = yes    
    (1)       } # update control = noop
    (1)     } # else = noop
