Have you seen my second mail, with the start of a patch?

Two things with "typedef struct { char * dn } smb_utf8_dn;": 

First, it makes it necessary to allocate two talloc contexts
per string, with twice the overhead. If we have many
strings, this might be significant and I would like to avoid
it if it is easily possible.

Second, why the typedef? And, why do you restrict its name to
"_dn"? I could imagine other uses than just the LDAP DNs.
