Good evening,

I see this bug in Ubuntu 16.04.1 LTS with autofs version 5.1.1-1ubuntu3 when I try to access cifs shares from my NAS.

When I try to access the shares with 'cd' or 'ls' after boot with network on both sides up and running I got the error message: "File or Directory not found." After running `sudo systemctl restart autofs.service` it works like a charme.

Here is my '''/etc/auto.master.d/diskstation.autofs''':
~~~
/home/tronde/diskstation /etc/auto.diskstation
~~~

And my '''/etc/auto.diskstation''':
~~~
music -fstype=cifs,uid=1000,credentials=/home/tronde/.smbcredentials ://IP-ADRESSE/music
photo -fstype=cifs,uid=1000,credentials=/home/tronde/.smbcredentials ://IP-ADRESSE/photo
share -fstype=cifs,uid=1000,credentials=/home/tronde/.smbcredentials ://IP-ADRESSE/share
video -fstype=cifs,uid=1000,credentials=/home/tronde/.smbcredentials ://IP-ADRESSE/video
home -fstype=cifs,uid=1000,gid=1000,credentials=/home/tronde/.smbcredentials ://IP-ADRESSE/home
~~~

This way autofs has no advantage over the manual mount with mount.cifs. Open this bug and fix ist, please.
