Hi,
We have a linux/samba only domain serving files to about 16-18 Windows
clients (mostly XP, a few W2K).
PDC:
SuSE OpenXchange 4.4
samba 2.2.8a
openldap 2.1.4
Domain Member Server (DMS)
CentOS 4.4
samba 3.0.10
I set the Domain Member Server up using the default passdb backend
(/etc/samba/smbpasswd) to start with and that all worked fine.
I would like to use LDAP for centralised authentication and have
re-compiled using --with-ldapsam because the PDC uses the older (Version
2) of the Samba LDAP schema. (see smb.conf below for params).
I've joined the DOMAIN with:
# net rpc join
Join to 'DOMAIN' is OK
I've set the ldap_bind_password in secrets.tdb with:
# smbpasswd -w <secret>
Setting stored password for "uid=root,dc=somedomain,dc=com" in
secrets.tdb
# smbclient -L DMS -N
gives the following error in the host log:
---8<---
auth/auth_domain.c:domain_client_validate(199)
domain_client_validate: unable to validate password for user root in
domain DOMAIN to Domain controller \\PDC. Error was
NT_STATUS_WRONG_PASSWORD.
---8<---
and when I try to connect to a share I get this:
# smbclient //DMS/share -U validuser
---8<---
auth/auth_util.c:make_server_info_info3(1177)
make_server_info_info3: pdb_init_sam failed!
---8<---
Connections directly to the PDC from the DMS work fine:
# smbclient //PDC/someshare -U validuser
Password:
Domain=[DOMAIN] OS=[Unix] Server=[Samba 2.2.8a-UL]
smb: \> quit
Can anyone please help with these errors? I can't seem to crack it open
myself
Thanks in advance,
Tom

[Samba] machine accounts mapped to non-unique uid (was make_server_info_info3: pdb_init_sam failed!)
Hi,
Well I partially fixed the problem myself but I'm still having trouble
connecting.
On the PDC I had to adjust the LDAP acl's to allow the DMS read access to
the
ldap databases.
On the DMS I used system-config-authentication to adjust /etc/nsswitch.conf, the
pam settings and /etc/ldap.conf so that nss_ldap is now called to retrieve
remote ldap information from the PDC.
Previous to the above changes pdbedit -L showed all users having the same uid
(4294967295). After the change, users have the correct and unique uid's but
all
the machine accounts still show the strange uid of 4294967295.
Is this still an LDAP acl problem or is it a samba configuration error?
client connects still fail with:
# smbclient //DMS/share -U DOMAIN/validuser
Password:
Domain=[DOMAIN] OS=[Unix] Server=[Samba 3.0.10-1.4E.9.ispl]
tree connect failed: NT_STATUS_NO_SUCH_USER
