A further modification did the trick. The structure holding the string to
use as a key also has a size attribute, which I suppose must be use when
the key is inserted into the file. Ordinarily drac sets this as being the
length of the string using strlen - of course strlen only measures up to
the first null byte in a string. Incrementing this size field by one,
though probably inadvisable, did the trick, and hosts that have logged in
can now relay as required. Unfortunately this appears to have had the side
effect of making drac not expire entries on cue anymore. This is another
story - I think I'll have to ask the writer of drac for help with this one.

Thanks for your help,

Mark
