2) you can use smbldap-passwd to change a user's password if you want to
set the passwd chat, unix password sync, etc. or you can just set ldap
passwd sync = yes and let samba handle the password changing directly
5) i think so, i have nss_ldap working because my users need shell
access for database/html work. i've never tried getting samba going
without using nss_ldap for user auth. i don't know if samba can look up
the users directly or if it gets their user, group, machine accounts via
nss_ldap. but nss_ldap is trivial to get working.
