[Samba] Re: Sharing Accounts between Servers and SIDs

To answer my own question: No, it doesn't work like this!
Samba coumplained about any SID I tried as being invalid.
(Unfortunately, I couldn't find any hint about what constitutes
a "valid" SID). Furthermore, It seems like when using the samba3
ldap_sam backend, samba wants to write all kinds of stuff into
the ldap directory (which does not work because the directory is
replicated and samba only has access to a read-only copy. For many
reasons, I also don't want samba to be able to write the LDAP
Is it possible at all to use the Samba3 ldapsam backend with this
setup? (With Samba2 it worked without any problem, starting with
Samba3 the focus of Samba shifted obviously mostly towards beeing as
windows-like as possible; right now I am using Samba 3.0.23b).
I am trying to keep out everything that only makes sense within a pure
windows domain controller based network - all I want is a bunch of
samba servers using a shared account database. The clients don't do
domain logons but just connect to single servers, which should consider
all users with a valid unix account as local users and authenticate based
on the lm/nt password hashes stored in the ldap directory.
Any help is appreciated,
