.bashrc_autoconnect.sh

share_mount_dir='/home/srudloff/shares'
vpn_connected=`ifconfig | grep "tun0"|wc -c`
if (( vpn_connected > 0 )); then
        if [[ $(keyring get VPN_SYSTEM DOMAIN | wc -c) -eq 0 ]];then
                keyring set VPN_SYSTEM DOMAIN
        fi
        SMB_DOMAIN=`keyring get VPN_SYSTEM DOMAIN`



        if [[ $(keyring get VPN_$SMB_DOMAIN USER | wc -c) -eq 0 ]];then

        fi
        SMB_USER=`keyring get VPN_$SMB_DOMAIN USER`

        if [[ $(keyring get VPN_$SMB_DOMAIN $SMB_USER | wc -c) -eq 0 ]];then
                keyring set VPN_$SMB_DOMAIN $SMB_USER
        fi


        if ! mountpoint -q "$share_mount_dir/shared/" || ! mountpoint -q  "$share_mount_dir/home"; then
                SMB_PASS=`keyring get VPN_$SMB_DOMAIN $SMB_USER`
        fi



        if ! mountpoint -q  "$share_mount_dir/home"; then
                echo "Mounting Work Home Drive"
                sudo mount.cifs "//SMB_PATH/home" $share_mount_dir/home  -o dom=$SMB_DOMAIN,pass=$SMB_PASS,user=$SMB_USER,vers=3.02,rw,dir_mode=0755,file_mode=0755,uid=1000,gid=1000
        fi


        if ! mountpoint -q "$share_mount_dir/shared/";then
                echo "Mounting Work Department Shared Drive"
                sudo mount.cifs "//SMBPATH/Shared" $share_mount_dir/shared/  -o dom=$SMB_DOMAIN,pass=$SMB_PASS,user=$SMB_USER,vers=3.02,rw,dir_mode=0755,file_mode=0755,uid=1000,gid=1000

        fi
fi

If you have any improvements please let me know
i was thinking of converting it to python so i could have a map of shares
