20 * We need to cache all LDAP querie results, they just take too long.
21 * We do hashing with chaining. Two caches are needed:
22 * 1) name -> uuid, indexed by a hash(f(): hashstring) of the name
23 * 2) uuid -> name, indexed by a hash of the uuid(f(): hashuuid)
24 * Both hash funcs result in a value 0-255 with which we index a array.
25 * We malloc and free all elements as needed.
26 * The cache caches for CACHESECONDS.
