[Samba] Upgraded a member server to 4.8, rfc2307 data?

I'm starting to upgrade my domain members to debian stretch/samba 4.8,
using louis packages.
Domain controllers still on jessie/samba45.

Upgrade went smooth, but after upgrade seems that the DM was not able
anymore to retrieve rfc2307 data, eg:

  root at vdmsv2:~# getent passwd gaio
  gaio:*:10000:10513:Marco Gaiarin:/home/LNFFVG/gaio:/bin/false

  root at vdmsv2:~# ldbsearch -H ldap://vdcsv1.ad.fvg.lnf.it -P -b
DC=ad,DC=fvg,DC=lnf,DC=it
"(&(objectClass=user)(sAMAccountName=gaio))"  | egrep -i
"(unixhome|shell)"
  loginShell: /bin/bash
  unixHomeDirectory: /home/gaio

smb.conf seems ok to me:

  root at vdmsv2:~# samba-tool testparm
  Press enter to see a dump of your service definitions
  
  # Global parameters
  [global]
	disable spoolss = Yes
	log file = /var/log/samba/log.%m
	log level = 0
	map to guest = Bad User
	max log size = 5000
	netbios aliases = MEDIASV
	panic action = /usr/share/samba/panic-action %d
	printcap name = /dev/null
	realm = AD.FVG.LNF.IT
	security = ADS
	username map = /etc/samba/user.map
	winbind nss info = rfc2307 # Samba 4.5-
	winbind offline logon = Yes
	winbind use default domain = Yes
	workgroup = LNFFVG
	idmap config lnffvg : unix_nss_info = yes	# Samba 4.6+
	idmap config lnffvg : range = 10000-49999
	idmap config lnffvg : backend = ad
	idmap config * : range = 5000-9999
	idmap config * : backend = tdb
	include = /etc/samba/smb.conf.%m

  [...]


What i'm missing?! Thanks.

Ahem read the logs, luke...

 [2018/09/04 16:37:11.137151,  0] ../lib/param/loadparm.c:398(lp_bool)
   lp_bool(yes	# Samba 4.6+): value is not boolean!

but now i've discovered that in smb.conf it is forbidden to use
comments after a keyword.


I'm sure i'm using that for years, but... sorry. ;-)

Hai Marco, 

The idmap config part. The this for the member. 

    ## map id's outside to domain to tdb files.
    idmap config *: backend = tdb
    idmap config *: range = 5000-9999

    ## map ids from the domain and (*) the range may not overlap !
    idmap config LNFFVG: backend = ad
    idmap config LNFFVG: schema_mode = rfc2307
    idmap config LNFFVG: range = 10000-49999

    idmap config LNFFVG: unix_nss_info = yes
    idmap config LNFFVG: unix_primary_group = yes


And about : 
[2018/09/04 16:37:11.137151,  0] ../lib/param/loadparm.c:398(lp_bool)
   lp_bool(yes	# Samba 4.6+): value is not boolean!

Put the comment above or below the line and see what happens. 

It looks like "yes	# Samba 4.6+" is seen as the value. 

Greetz, 

Louis

It is needed? AFAI've understood it means that users will have UNIX primary
group the windows group and not 'domain users', but reeally i don't
need

[Samba] Upgraded a member server to 4.8, rfc2307 data?

Hai Marco, 

If you dont need it, then you can remove it. 
And in addition to Rowland comment, i'll show how i use it. 

In reply to. >It is needed? AFAI've understood it means that users will have UNIX
primary group the windows group
>and not 'domain users', but reeally i don't need that...
I'll explain how i use it and why, maybe its useable for you or others. 

My windows group "Domain User" always the default for the users, it is
the default group for every user, except guests.
This is the windows default, i did assign GID's to 
"domain users"
"domain admins"	< most people dont use this or use with care on the
linux side.
"domain guest"
"domain computer" < most people dont use this or use with care on
the linux side.

And some other groups i need on linux, only the groups i need (on linux) have
GID assigned.
And yes, i did need all the "domain ...." groups in linux also.. I
needed these.
That why domain admins is having a GID. 

I do want my windows users to login on linux systems and use "Domain
Users" as primary group.

I use this to overcome some inherit problems.
Remember this, and this is the most important part imo. 
17XX "Creator Owner"
277X "Creator Group"
377X "Creator Owner and Creator Group"

/data 	root:"Domain Admins"	1755 ( allow everybody in this folder,
even guests )
	everyone can walk/enter this folder (/data) due to the last 5 in 1775 on linux.

/data/dep1	root:"Dep1"	 2770 ( allow users/group rights) and if member
of "Dep1" only then you can enter and read/write.
/data/dep2	root:"Dep2"	 2770 ( allow users/group rights) and if member
of "Dep2" only then you can enter and read/write.

If user1 creates a file in /data/dep1 , it creates it as user1:"Domain
User"
If user2 creates a file in /data/dep2 , it creates it as user2:"Domain
User"
But 
User1 is not able to access /data/dep2 due to the group restriction Dep1.
User2 is not able to access /data/dep1 due to the group restriction Dep2.

 >>  The headache points for people.   << 
Now my users switch departments, if wrongly setup, both users and read/write one
anothers files.
In my case, both users and read/write the created files from one another, no
headache ;-)

This is a bit how i setup my rights. ( depending on server and use of the server
).

And please note, this is only the LINUX PART of the rights. 
And best is to keep this as much as possible in line. 

I hope this helps a bit for you and others. 


Greetz, 

Louis
