Why not working next config? Thanks.
The documentation in the mods-available/cache file should be pretty clear.

It's looking up the string "control:Tmp-String-0" in the cache.  It's NOT looking up the value of that attribute.

  You will need to use:

   update reply {
      Tmp-String-1 = "%{cache_ldap:%{control:Tmp-String-0}}"
   }

  This expands the attribute, and then uses the value of the attribute as the key lookup.
