[Samba] security = user, LDAP, and adding users to ACLs

If your Samba is running as a PDC, and you are logged in the samba domain, you 
are able to list the LDAP users in the shares or files security tab, and you 
don't need winbind. All you need is nsswitch.conf configured with:

# /etc/nsswitch.conf 
passwd:         files   ldap 
group:          files   ldap 
shadow:         files   ldap

Plus ldap.conf like:

bindpw xxxxxxxx
binddn xxxxxxxxxxx
uri ldap://xxx.xxx.xxx.xxx
base dc=local,dc=loc 
rootbinddn xxxxxxxxxxxxxxxxxxxxx
ldap_version 3 
scope one 
ssl no 
pam_login_attribute uid 
pam_member_attribute gid 
pam_password md5 
nss_base_passwd dc=local,dc=loc?sub 
nss_base_shadow dc=local,dc=loc?sub 
nss_base_group ou=Groups,dc=local,dc=loc?one

In smb.conf you need to put something like:

ldap user suffix = ou=People
ldap machine suffix = ou=Computers 
ldap group suffix = ou=Groups
ldap suffix = dc=local,dc=loc
ldap admin dn = cn=xxxxxxxxxxxxxxxxxxxxxx 
ldap idmap suffix = ou=Idmap

Your LDAP must also have the default samba Domain Groups.
