Thank you for your answer In fact, it's working fine if i replace the "é" character with this sequence "\c3\a9"
To complete for finding à more simple solution : 1 - I precise that i use a normal command-line charset like chcp 1250 or chcp 850 with the Lucidia Font in the windows console that show correctly the accented characters in the windows command 2 - When i use ldapadd or ldapmodifiy, i have no problem with the accentes characters... but for this command i copy the .exe binaries from the OID 11g of oracle windows client... but in this product for windows there is not à ldapmodrdn.exe program... thanks for your help -----Message d'origine----- De : Michael Ströder [mailto:mich...@stroeder.com] Envoyé : mardi 8 septembre 2015 CG Nord 00:00 À : LAROCHETTE Philippe; openldap-technical@openldap.org Objet : Re: ldapmodrdn accented characters with windows client LAROCHETTE Philippe wrote: > I can't use ldapmodrdn command when some attributes like givenname > contains accented characters, the error is "Rename result: Invalid DN > syntax(34) > > > > My configuration is a server with Linux centos 7 and Openldap 2.4.35 > > > > The client is a windows XP where i copy the binarie ldapmodrdn.exe > from openldap for windows 2.4.32 > > > > When i launch this command for example on linux server it is ok but on > the xp client it doesn't work : > > > > ldapmodrdn -h xx.xx.xx.xx:389 -D cn=admin,c=fr -w yyyyyy -s "ou=TEST,c=FR" > "cn=TEST Véronique,ou=TEST2,c=FR" "cn=Myname Véronique" > > > > I think the problem is with the executable ldapmodrdn.exe.

Attribute 'cn' is of DirectoryString syntax (Unicode in UTF-8 encoding). I'd rather guess that some funky command-line charset is used on Windows. You could try the hex-escaped UTF-8 encoding (see RFC 4514) on Windows command-line which is not really convenient of course. Ciao, Michael.
