RE: UNICODE in OpenLDAP 2.0.11
I believe there are functions included in OpenLDAP to do conversions
i.e. ldap_x_utf8s_to_wcs and ldap_x_wcs_to_utf8s in utf-8-conv.c in

Thank you for the quick reply.
My problem is I'm afraid a bit more basic:
How does OpenLDAP support UTF-8? Is it supposed to do any conversions on
For instance, the dn_normalize() function is TOUPPER()-ing the buffer a
char at a time... Doesn't that work ONLY for single-byte coded
I guess my problem can be stated as "How can I develop an OpenLDAP
backend in C/C++, under WinNT/2000, which works correctly with umlaut-ed
Just basic directions would be enough.
I looked into the list archives but I don't seem to be able to manage
alone. Also,time is pressing me.
