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:
Posix file system permissions
server:/tmp # ll access
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/
# file: 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:
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 * \\10.1.1.1\linuxaccess /User:adtest<enter>
Provide the password<enter>
The above should provide something similar to the following:
Drive Z: is now connected to \\10.1.1.1\linuxaccess.
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.
