&author.jelmer; 25 October 2002 You might experience problems with special characters when communicating with old DOS clients. Codepage support has changed in samba 3.0. Read the chapter Unicode support for details. In 3.0, the following configuration options have been removed. printer driver (replaced by new driver procedures) printer driver file (replaced by new driver procedures) printer driver location (replaced by new driver procedures) use rhosts postscript client code page (replaced by dos charset) vfs path vfs options Effective with the release of samba-3 it is now imperative that the password backend be correctly defined in smb.conf. Those migrating from samba-2.x with plaintext password support need the following: passdb backend = guest. Those migrating from samba-2.x with encrypted password support should add to smb.conf passdb backend = smbpasswd, guest. LDAP using Samba-2.x systems can continue to operate with the following entry passdb backend = ldapsam_compat, guest.
