How to set up Samba to allow AD users in AD groups to access Samba shares

This document (7022492) is provided subject to the disclaimer at the end of this document.

How to configure Samba to allow AD users in AD groups to access Samba shares.

AD has a group with users in that group.

The AD group has a GID.

Samba is configured to authenticate AD users.

There is linux group with its own GID.

There is a Samba share that we want to give AD users access to by assigning the directory rights via the AD group.



AD Group:            ADG

GID for ADG:      10005

AD user in ADG:  adtest

Domain name:      AD199

Linux Group:              temp_local

GID for temp_local:   10003

Samba Share:         linuxaccess

The share definition in the /etc/samba/smb.conf file:


     path = /tmp/access

     read only = No

In the [Global] section of the /etc/samba/smb.conf file you might also want to set the following:

     winbind use default domain = yes

That way you can use the short user name adtest instead of domain/adtest

Restart the samba services after making changes to smb.conf and the winbind service if any winbind changes were made.

A quick way of doing this is “rcsmb restart; rcnmb; restart; rcwinbind restart” or “for i in rcsmb rcnmb rcwinbind; do $i restart; done”

Check that we can retrieve adtest the user from AD:

wbinfo -u




Posix file system permissions

server:/tmp # ll access

total 0

drwxrwx--- 1 root temp_local 18 Dec 13 16:38 GROUP_TEMP_LOCAL/

The owner is root and the group is the local linux group named temp_local.

server:/tmp/access # getfacl GROUP_TEMP_LOCAL/


# owner: root

# group: temp_local




In other words 770

Use YaST > Users and Groups > to change the GID of the temp_local linux group from 10003 to match the GID of the AD group named ADG which has a GID of 10005.

Show that the change was successful:

cat /etc/group | grep temp_local


Alternatively, doing an ‘id adtest’ shows the following:

id adtest

uid=10000(adtest) gid=10005(temp_local) groups=10005(temp_local)

Test cases:

Windows - DOS box

From a Windows machine DOS box accessing the linuxaccess share with the adtest user:

net use * \\samba_serverIP\samba_share /User:username<enter>

Example: net use * \\\linuxaccess /User:adtest<enter>

Provide the password<enter>

The above should provide something similar to the following:

Drive Z: is now connected to \\\linuxaccess.

Type Z:<enter>

Do a dir command to get a directory listing of this share.

Windows - Map Network Drive

Open File Explorer

Right click on “This PC” and select “Map network drive…”

Select the desired drive and on the “Folder:” enter \\samba_serverIP\linuxaccess

Click the box to check “Connect using different credentials” and select Finish.

User name: AD199\adtest

Password: <enter password>



Fom a Linux machine accessing the linuxaccess share with the adtest user:

smbclient //serverIP/linuxaccess -uadtest<enter>

Provide the password<enter>

Do a dir command to get a directory listing.
