  1. [Samba] Samba 3.2 Ldap problem

    Hi,
    I've running a samba 3.0.22-13.30 server in standalone mode (security=user) for quite a while. It's authenticated against an openLdap and works great, say Server A.

    A few days ago I've installed OpenSuSE 11 Beta 2 in another server, it came with samba 3.2.0-18, so as I'm very lazy I copied the smb.conf file from the working server to the new one with little modifications like the netbios name and which shares it serves, say Server B. I'm connecting to the same Ldap server.

    The problem is that I can't reach any share, from the Server B logs...

    [2008/07/01 04:54:01, 1] passdb/pdb_ldap.c:init_sam_from_ldap(567)
    init_sam_from_ldap: No uid attribute found for this user!
    [2008/07/01 04:54:01, 1] passdb/pdb_ldap.c:ldapsam_getsampwnam(1531)
    ldapsam_getsampwnam: init_sam_from_ldap failed for user 'xxxxx'!

    I've been "googleing" for the last 8 hours and I can't fix the problem, with a more verbose debug level I can see that the Ldap connection works fine. I've also checked the Ldap logs and everything is fine.

    May be it's a problem with idmap-ing.

    Here is my smb.conf file from the Server B, I've placed comments on lines which differ from the Server A and commented out lines I believe are not relevant to Server B.

    Have you looked in the LDAP log to see what attribute it's actually
    looking for? I haven't used 3.2 yet but I guess it's possible that
    something has changed with that.

    I don't think you need or want this since you are not a WINS server...

    Have you run smbpasswd -w to write the LDAP admin password into secrets.tdb?

    Only last night I was dealing with a terrible problem with 3.0.28a wih
    these two parameters. Try commenting these out and see if you can get to
    your share. Try naming individual users instead of groups. Also,
    apparently the required syntax for expanding groups has changed and I
    think it should be +DOMAIN\groupA and the like. Though I'm not sure that
    the '+' syntax is still favored either. You'll need to look in the docs
    for your version to verify this. Comment them out for testing anyway.

    Also I was made aware last night that it is better to set the sticky bit
    on the directory than to use 'force user' or 'force group' (thanks JHT).
    It will solve the 'create mask' too, I think.

  3. Re: [Samba] Samba 3.2 Ldap problem

    Have you installed the libnss-ldap module on Server B? It's required if you
    have your users in an LDAP-database.

    What do you see if you type the command on Server B:

    id

    For example, I have a user in my LDAP database, named "kissg_02a". In my
    case, I see the followings:

    root@lemontree# id kissg_02a
    uid=10003(kissg_02a) gid=513(Domain Users) groups=513(Domain Users)

    Try to set "loglevel 256" on your slapd.conf and look for entries in your
    syslog file, which have an "err" value, other than zero. If you don't have
    any, it means that communication with the LDAP-server works as expected, but
    Samba cannot access the uid attribute. It can also be, that the samba.schema
    file changed since Samba version 3.0, and the new version stores UIDs in a
    different attribute or in a different place of the LDAP directory structure.
    Check if there is a new version available for Samba 3.2.

    Best regards

  4. Re: [Samba] Samba 3.2 Ldap problem

    I think that you overlooked the SID

    In standalone mode you're not worrying about a domain - the data in LDAP is
    for your old server.

    The new samba installation has a new SID and it's doing its search in LDAP
    for that, finding no users.

    I've only used samba and ldap in a domain so don't know much about your
    options in standalone mode.

  5. Re: [Samba] Samba 3.2 Ldap problem

    The Ldap log sais nothing, every operation is fine, BUT, the samba log sais that it can't find the 'uid' attribute for the user. As I understand samba first tries to map the user with idmap (which I don't understand at all), then it makes the bind against the Ldap and last but not least enters the share specific permissions phase.

    Did you copy over the secrets.tdb as well? If not, you are going to
    have to use "net setlocalsid" to set the machine SID to match the old
    one, and "smbpasswd -w" to set the LDAP access password. Samba tracks
    users by SID now (which I don't like, personally, but it's something
    that the Samba Team apparently had to do if they wanted to
    interoperate with later versions of Microsoft's networking stack) so
    your users will have SIDs that were created by the old system.

    You also will want to put a "sub" index on the sambaSID attribute in
    OpenLDAP's slapd.conf file if you haven't already done so. Later
    versions of samba need it... you get a nice efficiency boost. Um, and
    watch your search limits in OpenLDAP also -the "machine suffix" and
    "user suffix" parameters in smb.conf are not applied as filters in the
    searches that samba makes in LDAP, so search returns might be bigger
    than you anticipate, and I'm not sure that samba can properly handle
    an RFC-compliant paged LDAP search result like OpenLDAP might return.

    I prefer using net setlocalsid and smbpasswd rather than just copying
    over an old secrets.tdb - but use tdbdump on the old one to see if
    there is anything else in there (like domain trust passwords) before
    you decide.

  7. Re: [Samba] Samba 3.2 Ldap problem

    Kissg,
    the ldap connection works fine, I've posted some ldap log lines and there is no problem there. I still believe the problem is in the idmap phase.

  8. Re: [Samba] Samba 3.2 Ldap problem

    Kevin, unix users works fine, I can login into the server with my username and password with both stored in the directory, the only "problem" here is that I don't have a home directory so I the Linux server warns me and assumes '/'.

  10. Re: [Samba] Samba 3.2 Ldap problem

    Ok, that's a posibility, I know very little about the protocol internals. On the contrary I used to have an old samba server (appart from server A) authenticating against the Ldap simultaneously with Server A.

    That old server is what I'm really trying to duplicate with a new installation on new hardware.

    Thanks, regards,

  11. Re: [Samba] Samba 3.2 Ldap problem

    Charlie,

    I didn't copied the secrets.tdb, I've used smbpasswd -w. In my Ldap I have an object named "sambaDomainName=OPEN,dc=my,dc=company" which I didn't create, it's automagically created by samba. That object has it's own sid, I've even deleted the secrets.tdb file and the ldap OPEN object, they are recreated with "smbpasswd -w xxxxx", so I assume everything is automagically right.

    In addition I've tried the index on sambaSID attribute, I already have an "eq" index on it, and I can't create a "sub" index, I think this is because of the attribute definition.

    I've updated to samba-3.2.0-21 but I'm still stuck.

    I'm worried about your comment on users located by sid as all my users already has a sid assigned, is that sid server-dependant? I must assume it isn't, it's only user-dependant, isn't it?

    Regards,
