Hi List, I'm running samba with ldapsam.With LDAP samba schema(sambaSamAccount),the required attributes are only sambaSID and uid.I use some attributes for my basic settings,but it seems that when connecting to samba server from other PCs ,it will automatically add other attributes(I think those are useless) my initial attributes(about samba) ------------ sambaSID sambaPrimaryGroupSID sambaLMPassword sambaNTPassword sambaAcctFlags add automatically by samba server -------------------------- sambaPwdCanChange sambaPwdMustChange sambaPasswordHistory sambaPwdLastSet Q: Why the samba server is doning that?Is that necessary?Can I make some changes to avoid this behavior? Thanks
