So I've been working on a script to map a users home drive, then use a file on there to map the rest of their drives. This is the code for the first part (redacted in some places):

#!/bin/sh

exec >> "/var/log/drive.log" 2>&1  ## must be run as admin or root for exec to work

sudo defaults write /Library/Preferences/com.apple.NetworkAuthorization AllowUnknownServers -bool YES


#Get the logged in users username
loggedInUser=`/bin/ls -l /dev/console | /usr/bin/awk '{ print $3 }'`

#Get logged in users home server
userHomeServer=$(dscl /Active Directory/COMPANY/All Domains -read /Users/$loggedInUser SMBScriptPath | awk '{if(NR>1)print}' | cut -c 14- | cut -c -6 | tr -d '[:space:]')

if [[ $userHomeServer == *"AU"* ]]
then
  echo "AU home drive"
  userHomeServer=$(dscl /Active Directory/COMPANY/All Domains -read /Users/$loggedInUser SMBScriptPath | awk '{if(NR>1)print}' | cut -c 14- | cut -c -8 | tr -d '[:space:]')
  echo $userHomeServer
elif [[ $userHomeServer == *"PHX"* ]]
then
  echo "PHX home drive"
  userHomeServer=$(dscl /Active Directory/COMPANY/All Domains -read /Users/$loggedInUser SMBScriptPath | awk '{if(NR>1)print}' | cut -c 14- | cut -c -9 | tr -d '[:space:]')
  echo $userHomeServer
elif [[ $userHomeServer == *"CH"* ]]
 then
 echo "CH home drive"
   userHomeServer=$(dscl /Active Directory/COMPANY/All Domains -read /Users/$loggedInUser SMBScriptPath | awk '{if(NR>1)print}' | cut -c 14- | cut -c -8 | tr -d '[:space:]')
   echo $userHomeServer
else
  echo "Normal Home Drive"
  userHomeServer=$(dscl /Active Directory/COMPANY/All Domains -read /Users/$loggedInUser SMBScriptPath | awk '{if(NR>1)print}' | cut -c 14- | cut -c -6 | tr -d '[:space:]')
  echo $userHomeServer
fi

homeDrive="Mount Volume "smb://COMPANY.com/SERVER/$userHomeServer/$loggedInUser""
echo "Home Drive: $homeDrive"

#Mount the network Drive
osascript -e "$homeDrive"

So it works fine and mounts the home drive. But there area cases when a user isn't logged in or a local admin is logged in. Also sometimes their extra drives file has drives which they don't have access to. So using this method, if there is an error it pops up they default "There was a problem connecting to server".

So was wondering if there is a stealthier method to map a network drive and if there is a failure of any kind, to just report it in the log file and not bother the user.

I think you could solve that issue with this:

if [[ "$(dscacheutil -q user | grep -A 2 "$loggedInUser" | awk '/uid:/ {print $2}')" -lt "9999" ]]
then
    echo "local user"
    exit
else
    echo "AD user"
fi

This is similar to what I use but with a lot less logic. This will determine if it is a local account and exit. This will look to see if the user has an SMBHome attribute in their user account, and if they don't it will exit. This will also determine if the mount was successful, and if not will exit abnormally.

#!/bin/bash

loggedInUser=$(/usr/bin/python -c 'from SystemConfiguration import SCDynamicStoreCopyConsoleUser; import sys; username = (SCDynamicStoreCopyConsoleUser(None, None, None) or [None])[0]; username = [username,""][username in [u"loginwindow", None, u""]]; sys.stdout.write(username + "
");')
accountType=$(/usr/bin/dscl . -read "/Users/$loggedInUser" | grep UniqueID | cut -c 11-)
ADHome=$(/usr/bin/dscl . -read "/Users/$loggedInUser" | grep SMBHome: | cut -c 10- | sed 's/\\///g')
# You need to change this to match what your mount point would look like
mountPoint="/Volumes/$loggedInUser"

[[ $accountType -lt "1000" ]] && echo "Local account; exiting." && exit 0
[[ -z "$ADHome" ]] && echo "No Value for AD Home returned" && exit 0

function mount_home () {
    ADHome="${ADHome/////smb://}"
    echo "Attempting to mount AD Home $loggedInUser..."
    /usr/bin/osascript -e "mount volume "$ADHome"" 2&> /dev/null
}

alreadyMounted=$(mount | grep "$mountPoint" | awk '{print $1}')
if [[ -z "$alreadyMounted" ]]; then
    if mount_home ; then
        echo "AD Home volume appeared to mount successfully."
        exit 0
    else
        echo "Error detected during mount, checking once more for AD Home..."
        if [[ ! -d "$mountPoint/$loggedInUser" ]]; then
            echo "AD Home not detected; beginning abort process."
            # Do something here if you want
            exit 1
        fi
    fi
else
    echo "AD Home volume appears to already be mounted at:"
    echo "     $alreadyMounted"
    exit 0
fi

Thanks guys! Will keep working on it. The user community seems to like this feature, but hate getting error messages. So seeing if I can find a middle ground.
