[Samba] DM: samba 4.5 -> 4.8, guest access and machine account access troubles.
I've just upgraded my DM from samba 4.5 to 4.8, using luois repos
(also, debian jessie -> stretch).
I'm experimenting some troubles on some shares, seems that both guest
access and 'machine account' access does not work.
The share is rather simple:
[wpkg]
browseable = No
comment = WPKG Automated Software Deploying System
force create mode = 0664
force directory mode = 02775
guest ok = Yes
path = /srv/samba/wpkg
wide links = Yes
I've got two troubles.
a) seems there's no more a guest access on the share. EG, if i use the
loca administrator user to access the share, i got 'access denied'.
Logs say:

clearly, i've on [globals] 'map to guest = Bad User'.
b) most of the WPKG scripts access the share with the SYSTEM users, eg,
using the machine account; seems this does not work anymore, even if
users seems mapped correctly and share permissione have permission to
'everyone' set.
Relevant log here seems:

So, while both errors seems to came froma 'guest access' trouble, they
are very different indeed.
I've tried to read samba changelog to seeks some clue, but with no luck
(or with no sufficient knowledge).
Please, help me. Thanks.

[Samba] DM: samba 4.5 -> 4.8, guest access and machine account access troubles.
Hai Marco, Few pointers. First, time is in sync? I guess it is, but check it. Second. Guest access enabled on a domain joint PC ? If you really really want that, then enable user guest in the AD also. But better is avoiding Guest access completely. Join the domain, dont allow guest access and configure it correctly, best tip i can give, for the software deploying share. [wpkg] path = /srv/samba/wpkg browseable = No comment = WPKG Automated Software Deploying System acl_xattr:ignore system acls = yes acl_xattr:default acl style = windows wide links = Yes Now setup the share from a windows client. On the Share tab: activate sharing. - Allow read access to that share for the special group "Domain Computers", or to everyone, and write access for yourself. - On the Security tab: grant read access to the special group "Domain Computers", or to everyone, and write access for yourself. And try again.

I guess it is, but check it.Yes.> Second. > Guest access enabled on a domain joint PC ? > If you really really want that, then enable user guest in the AD also.Eh? I need to enable guest access for every PC? In AD (i'm supposing that) i've correctly enabled guest access. See next response to Rowland.> But better is avoiding Guest access completely.Sure. But that share contain a bunch of script and xml files that i manage by linux, and really windows have only to read them, so... guest access fit perfectly! -- dott.

I restate, roughly the same config file on samba 4.5 permit correctly guest access from local Administrator user...> Not sure about this, perhaps it is the same reason as above, but we > need more info, what is in the [global] section of the smb.conf ?Domain member: # Global parameters [global] load printers = Yes log file = /var/log/samba/log.%M log level = 0 map to guest = Bad User max log size = 5000 netbios aliases = CUPSSV FILESV HOMESV panic action = /usr/share/samba/panic-action %d printcap name = cups realm = AD.FVG.LNF.IT security = ADS username map = /etc/samba/user.map winbind offline logon = Yes winbind use default domain = Yes workgroup = LNFFVG spoolss: architecture = Windows x64 rpc_daemon:spoolssd = fork rpc_server:spoolss = external idmap config lnffvg : unix_nss_info = yes idmap config lnffvg : schema_mode = rfc2307 idmap config lnffvg : range = 10000-49999 idmap config lnffvg : backend = ad idmap config * : range = 5000-9999 idmap config * : backend = tdb printing = cups root at vdmsv1:/etc/samba# cat /etc/samba/user.map !root = LNFFVG\Administrator LNFFVG\administrator Administrator administrator domain controller (still samba 4.5): [global] netbios name = VDCSV1 realm = AD.FVG.LNF.IT server services = s3fs, rpc, nbt, wrepl, ldap, cldap, kdc, drepl, winbindd, ntp_signd, kcc, dnsupdate workgroup = LNFFVG log level = 0 server role = active directory domain controller template homedir = /home/%U template shell = /bin/bash idmap_ldb:use rfc2307 = yes Thanks. -- dott.

[Samba] DM: samba 4.5 -> 4.8, guest access and machine account access troubles.
Hai marco, It has nothing todo with samba and it has all todo with samba and windows combined.> Sure. But that share contain a bunch of script and xml files that i > manage by linux, and really windows have only to read them, > so... Guest access fit perfectly!Imo a bad idea, but hee.. Its your network.. Only trying to help here. And : https://docs.microsoft.com/en-us/previous-versions/windows/it-pro/windows-server-2008-R2-and-2008/cc755130(v=ws.11) Is telling : The Guest account is disabled by default, and we recommend that it stay disabled.> > b) most of the WPKG scripts access the share with the SYSTEM users, > eg, using the machine account; seems this does not work anymore, even > if users seems mapped correctly and share permissione have permission > to 'everyone' set.Yes, correct, because SYSTEM is not guest or nobody. Its SYSTEM. This is your problem, one you created yourself. (sorry) This has all todo with the windows security updates of the last 1.5 years. Samba 4.5 is not the same as 4.8, and security has been up a lot. This is why i follow the windows way and transform these settings into samba. ( as close as possible ) Whats results in a hardly having any problems. I suggest try the settings like this then. [wpkg] path = /srv/samba/wpkg browseable = No comment = WPKG Automated Software Deploying System acl_xattr:ignore system acls = yes wide links = Yes You see i removed 1 line the : acl_xattr:default acl style Now with posix you should be able to manage this from linux and use it on windows. ( without guest ) And you really only need. But you do need the correct settings configured from windows computer for the share and security rights. Sorry, i dont have an other settings (that i can recommend), i try to follow the MS recommendations, just because it helps in avoiding problems. And i know this works. I deploy with GPO, useing the same settings. ( except the wide links. ) I dont see why that should not work with WPKG. This is what i use for the software i deploy with GPO.
