I have been struggling for several weeks trying to get samba 3.01 running as a PDC under LDAP. I think my problem lies in my configs for pam.login and pam.samba. I have been unable to find example configs anywhere which are specifically for LDAP authentification. I may be wrong, but I see the examples in chapter 25 of the Samba Project Documentation as being for a separate smbpasswd database and I do not see an example for an LDAP backend. If anyone who has a successfull Samba PDC with LDAP authentication would post examples I would be very grateful. Curtis Grote Memorial Hospital
