Your statement definitely makes sense. The point I get, from reading
thru the code, is that while it is easy to aliase a normalized dn, it
gets a bit more difficult to aliase a non-normalized dn, so the added
dn should be normalized and would look a bit "square".  The fix would
be to also store the (supposedly) non-normalized alias entered in
the config file and try to use it to get a non-normalized aliased 
version of the new dn.  I'm not sure it is worth the effort; in fact
I remember reading about issues involving suffix aliasing in previous 
postings, which implies subtle side-effects.  I'm not sure what was
the real drawback.  If there's a real need I'll try to work something
