Operating Systems AIX Samba 3.6 on AIX 7.1 - Windows 10 Access to AIX file shares using Active Directory authentication Post 303039870 by linuxsnake on Wednesday 16th of October 2019 04:02:33 PM

I have managed to install samba and kerberos and configured smb.conf, krb5.conf and methods.cfg

I ran the following commands to join the Windows Domain from AIX:

1) kinit <username> using my current Windows user name that I log on to the domain with. Initially I had some problems with time synchronisation (scew time was out). To resolve this I configured ntp daemon pointing it to the domain server and I forced a time synchronisation. After this the command worked and I generated a kerberos key.

2) net ads join -U <username> using my current Windows user name that I log on to the domain with.

Both these commands worked so I joined the Windows domain.

At this stage I ran some test commands:

wbinfo --ping-dc - This came back positive as SUCCESS

wbinfo -g - This brings back a list of all domain groups on the domain controller
wbinfo -u - This brings back a list in unix of all the windows user names on the domain controller

Samba appears to be running ok however the folder I'm trying to share on AIX is still not visible when I try and access it via Windows \\unixserver\sharename . No errors it just isn't recognised by windows as a share.

I logged on a Windows machine to see if my Unix machine can be found in Active Directory. I found it listed under computers (its a member of one group - domain users)

I have 2 questions so far:

1) When configuring Kerberos all the guides refer to winbind settings in methods.cfg

There is a reference in this config file to WINBIND and DCE file locations:

Code:

WINBIND:
        program = /usr/lib/security/WINBIND
        program_64 = /usr/lib/security/WINBIND_64
DCE:
        program = /usr/lib/security/DCE

When I check my AIX system these files do not exist. I ran a find searching the whole system. /usr/lib/security exists but WINBIND , WINBIND_64 and DCE do not exist. The latest winbind packages have already been installed via yum so I'm on the latest version for AIX 7.1

In /opt/freeware/lib/security there are 2 files pam_winbind.so and pam_smbpass.so. I believe I may need to copy these to /usr/lib/security ?
The question is why dont I have WINBIND or WINBIND_64 on my system and how do I get hold of these? I presume I need methods.cfg to use these WINBIND library files in order for my fileshare to work?
I don't need to authenticate users to login to the unix shell. I just need a group of windows users (from one AD group) to access an AIX fileshare (without a requirement to enter a password) - authenticating using active directory account.

2) Currently I have joined the domain as a regular windows user. This allows me to interrogate Active Directory and list all users and groups. I presume to get this working correctly I will need to join the domain as a Windows user with a higher level of rights (perhaps domain administrator rights?). Can anyone tell me what group the Windows user should be a member of to get file sharing working so a specific AD group of Windows users can access a shared AIX folder authenticating with their windows password (no need to enter one)? I'm guessing my regular Windows user account won't give me what we need.

I've switched logging up to 3 for samba.log to try and give me an idea of why this is failing but if anyone has got this working appreciate any suggestions.

cupsaddsmb(8)							    Apple Inc.							     cupsaddsmb(8)

NAME

       cupsaddsmb - export printers to samba for windows clients

SYNOPSIS

       cupsaddsmb [ -H samba-server ] [ -U samba-user[%samba-password] ] [ -h cups-server[:port] ] [ -v ] -a
       cupsaddsmb [ -H samba-server ] [ -U samba-user[%samba-password] ] [ -h cups-server[:port] ] [ -v ] printer [ ...  printer ]

DESCRIPTION

       The  cupsaddsmb	program  exports  printers to the SAMBA software (version 2.2.0 or higher) for use with Windows clients.  Depending on the
       SAMBA configuration, you may need to provide a password to export the printers.	This program requires the  Windows  printer  driver  files
       described below.

   SAMBA CONFIGURATION
       cupsaddsmb  uses  the RPC-based printing support in SAMBA to provide printer drivers and PPD files to Windows client machines.  In order to
       use this functionality, you must first configure the SAMBA smb.conf(5) file to support printing through CUPS and provide a  printer  driver
       download share, as follows:

	   [global]
	    load printers = yes
	    printing = cups
	    printcap name = cups

	   [printers]
	    comment = All Printers
	    path = /var/spool/samba
	    browseable = no
	    public = yes
	    guest ok = yes
	    writable = no
	    printable = yes

	   [print$]
	    comment = Printer Drivers
	    path = /etc/samba/drivers
	    browseable = yes
	    guest ok = no
	    read only = yes
	    write list = root

       This configuration assumes a FHS-compliant installation of SAMBA; adjust the [printers] and [print$] share paths accordingly on your system
       as needed.

   MICROSOFT POSTSCRIPT DRIVERS FOR WINDOWS
       The base driver for Windows 2000 and higher is the Microsoft PostScript driver, which is available on any system running  Windows  2000	or
       higher  in  the	%WINDIR%SYSTEM32SPOOLDRIVERSW32X863  folder  for  32-bit drivers and %WINDIR%SYSTEM32SPOOLDRIVERSX643 folder for
       64-bit drivers.

       Copy the 32-bit drivers to the /usr/share/cups/drivers directory and  the  64-bit  drivers  to  the  /usr/share/cups/drivers/x64  directory
       exactly as named below:

	   ps5ui.dll
	   pscript.hlp
	   pscript.ntf
	   pscript5.dll

       Note:  Unlike  Windows, case is significant - make sure that you use the lowercase filenames shown above, otherwise cupsaddsmb will fail to
       export the drivers.

OPTIONS

       cupsaddsmb supports the following options:

       -H samba-server
	    Specifies the SAMBA server which defaults to the CUPS server.

       -U samba-user[%samba-password]
	    Specifies the SAMBA print admin username which defaults to your current username.  If the username contains a percent  (%)	character,
	    then the text following the percent is treated as the SAMBA password to use.

       -a   Exports all known printers.  Otherwise only the named printers are exported.

       -h cups-server[:port]
	    Specifies a different CUPS server to use.

       -v   Specifies that verbose information should be shown.  This is useful for debugging SAMBA configuration problems.
