I've got a (semi) working setup using openldap and samba in a domain where user passwords are shared across multiple samba based PDCs (As per suggestions from this list, all samba machines are PDC or BDC). These systems are designed to provide a collection of file services with a unified username/password to an assortment of laptops and desktops which may not be permanently joined to the domain. as it turns out, running a domain for single signon causes a bunch of problems, not the least of which are: 1) permissions cannot be set for printers without joining a system to the domain, then local users can't print from joined systems (but can print from non-joined systems, wth?), which leads to.. 2) After a trial join, it became immediately apparent that even joining the domain was infeasable for any period of time. 3) browsing domain+workgroup computers doesn't always work properly. At the end of the day I've come to a conclusion. it's time to separate these two systems into non-domain samba servers. However, I still want to have them use the single LDAP directory to handle a central password repository. can they do this? will I be able to have two different systems with different domains (host names) and SIDs have unified passwords using ldap ? or will I have to resort back to using local smbpasswd stores?
