[Samba] Charset disaster moving from 2.2.8 to 3.0.4

[Дорофеев Михаил Сергеевич]

Hi all!
I'm REALLY depressed!
After moving from samba 2.2.8 to 3.0.4 I can not read my files. 
All names are corrupted.
I used NO charset options in the original (2.2.8) smb.conf 
(which means that all names are in cp850, doesn't it ?)

No I have installed 3.0.4, libiconv also.
But can not figure out what to set in smb.conf.
I use Solaris 8, LC_CTYPE=ru_RU.KOI8-R.
And windows XP/2000 clients.

Have already tried billions of combinations starting from 
       dos charset = CP866
        unix charset = KOI8-R
Etc....

I've read about also ant tried to 
./convmv -f cp850 -t iso8859-1  -r /export/home/papers

But I DID NOT get the result.

What am I doing wrong ?
PLS, help!!!
There are TONNS of useful information there...
