+<WRAP center round important 60%>
+**2022-11-30**: Please note that I have discovered, that this howto is more complicated than it needs to be and is not taking advantage of the flexibility offered by autofs. But... It will work for ONE user who needs shares from ONE server mounted into his/her/... home.
+Anyway, this howto needs refactoring... stay tuned.

 ====== automount CIFS share with autofs ======
 This HowTo will prepare a Linux client to automatically mount CIFS shares from a remote Samba server on access/demand. Since I am mounting different filesystems, I have structured my mountpoints as follows:
+<code>
 /
 ├── home
@@ Line 19: / Line 24: @@
 │   │   │   ├── sshfs
 │   │   │   │   ├── ssh-server-a.fqdn
+</code>
 From here on, I will use “mysambaserver.local” as the Samba servers FQDN, “mysambaserver” as its hostname, “myusername”  as my username, “mygroup” as group and “myPassWord” as the password.

 This file is a slightly modified version of the file auto.smb which usually comes as part of the autofs package. You need to modify the line defining the mountopts above and change userid and groupid to the uid/gid of your personal account.

 The maps to be monitored are specified in this file.
 Execute the following command to append the line “/home/myusername/mnt/cifs /etc/auto.mysambaserver-cifs –timeout=60” at the end of the /etc/auto.master file:
+<sxh bash; gutter: false>
 echo "/home/<myusername>/mnt/cifs /etc/auto.<mysamabaserver>-cifs --timeout=60 --ghost" >>/etc/auto.master
+</sxh>
 The syntax here is: <Directory> <Map-File> [Parameter]
 The shares should be unmounted after an inactivity of 60 seconds (–timeout=60) and empty directories should be created for the individual shares before mounting (–ghost).
