Hi, although reading through various docs I'm still having trouble with the charset conversion. The Samba server is version 3.0.22 (on Gentoo). Locales are: GDM_LANG=en_US.utf8 LANG=en_US.utf8 LANGUAGE=en_US.utf8 LC_ADDRESS=en_US.utf8 LC_ALL=en_US.utf8 LC_COLLATE=en_US.utf8 LC_CTYPE=en_US.utf8 LC_IDENTIFICATION=en_US.utf8 LC_MEASUREMENT=en_US.utf8 LC_MESSAGES=en_US.utf8 LC_MONETARY=en_US.utf8 LC_NAME=en_US.utf8 LC_NUMERIC=en_US.utf8 LC_PAPER=en_US.utf8 LC_TELEPHONE=en_US.utf8 LC_TIME=en_US.utf8 In smb.conf I've added dos charset = UTF8 unix charset = UTF8 display charset = UTF8 All Linux machines use de_DE.utf8, except one on which all german umlauts are messed up using POSIX/C. How do I have to configure charset conversion and upper/lower case to get the Samba server working correctly with Linux-UTF-8 clients, MacOS clients, Windoze clients and which charset options do I have to use with smbmount on the Linux-POSIX/C client? Thanx for any hint Renne
