[Samba] sharing an autofs nfs mount

[L.P.H. van Belle]

What "works for me" 

I have a webserver serving my SFTP service. 

I use SecureShell package for the SFTP/SCP service
Secure shell, makes it easy to set a chrooted homedir. 
I set NIS (* not really needed but i use RSAT ADUC) 
UID set 
Homedir /srv/nfs/customers/SomeUsername/spool

Primary gid to a linux/windows group, WITH GID assigned. 
The login is an automounted folder in this case NFS. 
*( unless you use cifs, then keep "domain users" ) 

Now this works fine here with NFS and CIFS automounts for me. 
Just keep in mind i "want/need" the chroot and nothing else. 


The systemd file to mount the share. 

/etc/systemd/system/srv-remote-customers.mount
#------------
[Unit]
Description=Mount Remote Customers Homedirs


[Mount]
# NFS option. 
What=FQ.DN:/exportnfs/customers
Where=/srv/remote/customers
Type=nfs

# Cifs Option
What=//FQ.DN/customers
Where=/srv/remote/customers
Type=cifs
Options=credentials=/etc/samba/credentials-administrator,rw,vers=3.0
# content : /etc/samba/credentials-administrator
username=Administrator
password=XXXXX
domain=ADDOM

[Install]
WantedBy=multi-user.target
#------------

And the automount file. 

/etc/systemd/system/srv-nfs-customers.automount
#------------
[Unit]
Description=Automount Remote Customers Homedirs

[Automount]
Where=/srv/remote/customers
TimeoutIdleSec=120

[Install]
WantedBy=multi-user.target
#------------

Make sure the needed packages are installed. *( like cifs-utils/nfs-common on debian) 
Make sure you have nfs/fq.dn and cifs/fq.dn in you keytab 

Place both files in /etc/systemd/system 
systemctl daemon-reload
systemctl enable srv-remote-customers.automount

And test.
