Hello, Until now samba authentify users against a nis? database. I just only want the same thing but that samba looks for login/password against a ldap server to identify users. I run samba-3.0.32 on fedora core 9. I enter the command below so my server can read ldap : smbpasswd -w read_pasword When I write login/password in authentification box on the client windows XP it doesn't work ! On the slapd.log I read : Oct 10 11:51:54 host1 slapd[24570]: conn=16 op=3 SRCH base="dc=ourdomain,dc=fr" scope=2 deref=0 filter="(&(uid=frontin)(objectClass=sambaSamAccount))" In /var/log/samba/myhost.log I find sam_account_ok adn logon_hour_ok Any ideas !
