mount

apt install cifs-utils samba samba-client

mount.cifs //some-cifs.example.com/someshare somemount/ -o dom=ad,user=someuser,pass=SomePA@@

mount.cifs //myserverhere.com/cifs_share /mnt/cifs_share \
   -o user,uid=65001,rw,workgroup=DEV,credentials=/root/.cifs

/root/.cifs:
 username=ouruser
 password=ourpassword

Add domain if needed:

 domain=domain

//[URL]/[sharename] /media/[mountpoint] cifs vers=3.0,credentials=/home/[username]/.sharelogin,iocharset=utf8,file_mode=0777,dir_mode=0777,uid=[username],gid=[username],nofail 0 0

sudo chmod 0600 /root/.cifs

Note this works:

username=user@example.com

And this works:

username=userid
domain=AD

But these forms do NOT work:

username=AD\userid
username=AD\\userid
username=AD//userid
