Usermin can't change samba password - no errors in miniserver.error

[michael sunday]

Hi

I have a Webmin 1.760 and Usermin 1.670 in FreeBSD 8.3. Server has samba3.0.23c with security in share level. I configure samba in webmin with "Change the Samba user when a Unix user is changed". But when I change password in Usermin nothing happens with samba password. No error in miniserver.error. I don't have "Your Samba password for windows file sharing has also been changed." in Usermin change password description. When I install samba the default directory was /usr/local/samba and in config module I'm set smbpasswd for /usr/local/samba/bin/smbpasswd. I have no idea what I do wrong
This is my samba config
sync_gid=
samba_server=/usr/local/samba/sbin/smbd
