samba - Jan 2006 - Samba 3 and german umlaute in filenames/ can not delete or rename files or dirs

Hello,

i habe an Sama 3 Server with some shares.

If I access these shares from Windows and if I generate new files or dirs with 
german umlaute everythink is OK.
I can open theses files and I can open the directory.

If I want do delete or rename the files or dirs with german umlaute I got an 
error message. "I can not read the file from source".
