Could you please tell me how did you enable samba authentication via LDAP ? I saw your post but could not find any steps :(
Thanks in advance.
There are "ldap" options group in smb.conf. For example:
Then you have to use 'smbpasswd -w ldapppassword' to store password, which samba will use to connect to LDAP database. Google 'smbldap-tools' for more explanations.
