Li, it seem indeed that we are not freeing the tmp_ctx at the end of the
function, but I need some time to read that code in detail to make sure
we are not returning some of that memory to the caller.
In any case, the memory is not completely leaked as it hangs on the
mem_ctx passed to lookup_sids(), as soon as the caller frees that
context all that memory is freed.
