Authentication successful with empty or incorrect Domain string

[Smita Zankar]

Hi,

I have Samba PDC setup on RHEL. I have another RHEL joined to the Samba PDC
domain for authentication, I have also configured the PAM modules with
winbind.
The authentication works with username as "\user" or "pdc\user" even even
the Domain name for the Samba PDC is different e.g. "SambaPDC". This is seen
with a sample authenticaion using smbclient as well as if I try ssh/ftp/scp.

My question is why the domain string is not getting matched during
authentication? Is there any specific configuration change required.

My Samba PDC, smb.conf looks like:
[global]
        workgroup = MyDomain
        server string = Samba PDC
        netbios name = sonas18
        passdb backend = tdbsam
        log level = 3
        log file = /var/log/samba/%m.log
        max log size = 50
        add machine script = /usr/sbin/useradd -n -c "Workstation (%u)" -M
-d /nohome -s /bin/false "%u"
        domain logons = Yes
        os level = 64
        preferred master = Yes
        domain master = Yes
        wins support = Yes
        cups options = raw
        security = user
        encrypt passwords = Yes
        idmap gid = 10000000-11000000
        idmap uid = 10000000-11000000


[netlogon]
        path = /etc/samba/netlogon
        writeable = no
        write list = ntadmin
        guest ok = no
[profiles]
        path = /usr/smb/ntprofile
        writeable = yes
        create mask = 0600
        directory mask = 0700



My Samba client smb.conf looks like:
(relevant entrries)
        server string = "linux1"
        ea support = yes
        groupdb:backend = tdb
        template homedir = /var/opt/scproot
        dmapi support = no
        workgroup = mydomain
        password server = 9.182.193.218
        security = domain
        disable netbios = no
        template shell = /usr/bin/rssh
        idmap gid = 10000000-11000000
        idmap uid = 10000000-11000000
        netbios name = so18


Any help is appreciated.

Thanks,
Smita
