[Samba] User password change

2013-09-26 Thread Bruno Vane

I have a beginner doubt in Samba4.
I managed to make my SSH users authenticate against Samba4 AD DC without
joining the SSH server in the domain, with the great help of you guys from
this list. Is there a way for users to change the password via the
passwd? When I try to change the password, I get a success message, but
actually does not work. Is this possible?


I followed the instructions from
https://wiki.samba.org/index.php/Samba4/beyond

bruno.vane@ldap:~$ passwd
Enter login(LDAP) password:
New password:
Re-enter new password:
LDAP password information changed for bruno.vane
passwd: password updated successfully

2013-08-29 Thread Bruno Vane

Thank you Steve,

I had this mapping in nslcd.conf
map passwd  gidNumber   primaryGroupID

I need the gidNumber to be 100 because this is gidnumber of group users
in my Ubuntu servers.
I will disable this mapping and test if everything is OK.

 Hi

 How are you obtaining the infromation from AD?
 If you set:
  gidNumber: 100
 in the DN of a user, then that is what will be returned when e.g.
 nss-ldapd is used. It will not return primaryGroupID unless you have
 mapped that attribute to gidNumber in nslcd.conf. primaryGroupID is not
 a rfc2307 atribute.

 The mapping is not just for mapping one field to an other. You can replace
 values, too or do other things (see manpage for more).

 You can hardcode the mapping:

 map passwd  gidNumber  666


 # getent passwd
 ...
 Administrator:*:1:666::/**home/Administrator:/bin/bash
 technik:*:10001:666:Technik:/**home/technik:/bin/false
 demo1:*:10002:666:Demo User1:/home/demo1:/bin/sh


 And all your domain accounts have primary group 666 :-)


 Regards,
 Marc

Hi Luca,

If you provisioned your domain with --use-rfc2307, then in Win7 ADUC you
can see the posixAccount (UNIX Attributes) of the users.

  Now I can see the unix tab, but, whenever I click accept, it tells me

  There could be a network problem. Active Directory could be down.
  Contact your system administrator.
 
  However, when I open the user again I can see the modified unix

  it's missing the posixAccount class:
 
 
  I only used a very short time XP together with Samba AD. But I remember,

 Not right now, but I'll try when I manage to setup a W7 VM.
 Does windows 7 ADUC add the posixAccount class?

[Samba] Change default GID of users

2013-08-27 Thread Bruno Vane

Hi all,

I'm using samba4 as DC and using ssh/nslcd/pam in some machines to lookup
ldap base in samba4 to allow access for users.
My question is, how can I set the default GID os users to 100, to match
the GID of groupusers in my linux machines? All users I create with ADUC
is getting UID 513. This machines are joined in the domain.

This is my groups:
root@samba:~# wbinfo -g
Enterprise Read-Only Domain Controllers
Domain Admins
Domain Users
Domain Guests
Domain Computers
Domain Controllers
Schema Admins
Enterprise Admins
Group Policy Creator Owners

This is GID's:
CORPORATIVO\Domain Admins:*:308:
CORPORATIVO\Domain Users:*:100:
CORPORATIVO\Domain Guests:*:312:
CORPORATIVO\Domain Computers:*:318:

Thank you Marc,

I will try this configuration. For this to work I need openLDAP proxy?

 I think this shouldn't matter. You can configure the entry host with
 nslcd to retrieve the account information via LDAP from AD and pam_ldap to
 authenticate against AD (without necessity to join the machine to the
 domain).

 Then you have the other hosts. These you can authenticate on the same way,
 if they are not joined to the domain, or you join them and the
 authentication is done through winbind.




 For the nslcd you can use the following config (you must create an bind
 account in your domain for that first):

  #Mappings for Active Directory
  pagesize 1000
  referrals off

  # Passwd
  filter  passwd ((objectClass=user)(!(**objectClass=computer))(**
 uidNumber=*))
  map passwd  uid sAMAccountName
  map passwd  homeDirectory   unixHomeDirectory
  map passwd  gecos   displayName
  map passwd  gidNumber   primaryGroupID

  # Shadow
  filter  shadow ((objectClass=user)(!(**objectClass=computer))(**
 uidNumber=*))
  map shadow  uid sAMAccountName
  map shadow  shadowLastChangepwdLastSet

  # Groups
  filter  group ((objectClass=group)(**objectClass=posixGroup)(**
 gidNumber=*))
  map group   uniqueMembermember

  # Local account, nslcd runs under
  uid nslcd
  gid ldap

  # LDAP server settings
  uri ldap://127.0.0.1:389/
  base dc=SAMDOM,dc=example,dc=com

  # Account in AD that is used from Nslcd to bind to the directory
  binddn CN=nslcd-connect,cn=Users,dc=**SAMDOM,dc=example,dc=com
  bindpw x



 pam_ldap config you find here:

Marc, it seems that the problem was actually that the posix information

option --use RFC2307. After creating the user in AD (via RSAT in Win7) I
need to manually enable NIS domain info for that user. After this, I got to
access via SSH using the Samba4 LDAP. Now i have to research how to
auto-create the home dir and change the shell to /bin/bash.
Very thank you for your help!

 Of course this would only work if you have posix information in your
 directory.

 If you don't want to manage them in AD, you can use winbind or sssd. But
 there you have other requirements (machine joined to domain, kerberos, ...).

Hi Ricky,

I'm not using winbind.
To auto create home dir I added:
session required  pam_mkhomedir.so skel=/etc/skel umask=0022

in /etc/pam.d/common-session file.

I'm using Marc instructions to log in via SSH whithout join the machine in
the domain. Can I also use winbind with this setup?


2013/8/26 Ricky Nance ricky.na...@gmail.com

 If you are using winbind, you can use template home directory = and
 template shell = in your smb.conf (man smb.conf for a more accurate
 description)..

 You add the attributes yourself when you create the user:

 samba-tool user add luca --uid-number=1234567 --gid-number=45678
