Comment 37 for bug 1113395

Migrating from Ubuntu 12.04LTS to 16.04LTS also brokes cifs mount for me. I was having following in my fstab file:

/192.168.10.1/server_share/ /mnt/my_point cifs iocharacterset=utf8,sec=ntlm,credentials=/home/kruno/.smbcredentials,uid=1000,gid=1000 0 0

As I read elsewhere you need to separate username and domain in credential file. I did that too. Still having permission denied errror when try to use "mount -a" command

I also tried to put username, domain and password directly in fstab command. Same errror.
I'm sure that username and password is correct, because following command properly mount drive:

mount -t cifs //192.168.10.1/server_share/ /mnt/my_point -o username=my-username,password=my-password,domain=MYDOMAIN

Finally, found elsewhere that "mount -a -v" command can give more data. After that I got this response:

mount.cifs kernel mount options: ip=192.168.10.1,unc=\\192.168.10.1\server_share,iocharacterset=utf8,sec=ntlmv,uid=1000,gid=1000,user=my-username,,domain=MYDOMAIN,pass=********

Please note double "," between username and domain. Happens with both, using credential files and direct input of username and password trough fstab command line.

My server that I try to cennect to is still on ubuntu 12.04LTS while client is 16.04

I hope that this bit of info can help to solve this bug
