Recently installed Fedora core 6 to support, amongst other things, Radius-based JANET roaming service. (http://www.ja.net/roaming/) To do that we want to authenticate against our existing Windows Active Directory, and are hoping to use ntlm_auth as described at http://www.ja.net/roaming/documents/jrs-compliance-case-study.pdf Samba (& everything else) installed as default on Fedora, and updated to current level with yum: samba.i386 3.0.23c-2 installed All of Samba seems to work except ntlm_auth. PAM, krb5, and niss are configured, winbindd is running. We can join the domain, list resources, use smbclient, & so on. When we try ntlm_auth we see this: # ntlm_auth ntlm_auth: error opening config file /etc/samba/smb.conf. Error was Invalid or incomplete multibyte or wide character But /etc/samba/smb.conf is perfectly fine as far as we can tell. Also we see the same error when using a 0-byte empty /etc/samba/smb.conf Any clues? Ken Brown CCS Systems Team Birkbeck College
