I do this by running a preexec script from smb.conf:

[home]
root preexec = /usr/local/sbin/mkshare_user_dir home '%P' '%U'

[profiles]
root preexec = /usr/local/sbin/mkshare_user_dir profile '%P' '%U'

[folders]
root preexec = /usr/local/sbin/mkshare_user_dir folder '%P' '%U'


The script is like this (adjust it to your needs):

#!/bin/bash
# This is runs on every login !!
declare -A MODE
MODE["user"]="2770"
MODE["profile"]="0700"

PROFILE_VERSION="V6"

SHARE_KEY=$1  # home, folder, profile
SHARE_PATH=$2
USER_NAME=$3

echo "home folder profile" | grep -qw "${SHARE_KEY}" || exit 0

[[ "${SHARE_KEY}" == "profile" ]] && SHARE_TYPE='profile' || 
SHARE_TYPE='user'

USER_PATH="${SHARE_PATH}/${USER_NAME}"
GROUP_NAME="grp_${USER_NAME}"
if [[ "${SHARE_KEY}" == 'profile' ]]; then
     USER_PATH="${SHARE_PATH}/${USER_NAME}.${PROFILE_VERSION}"
     GROUP_NAME='domain users'
fi

if [[ ! -d "${USER_PATH}" ]]; then
     mkdir "${USER_PATH}"
     chown "${USER_NAME}":"${GROUP_NAME}" "${USER_PATH}"
     chmod "${MODE[$SHARE_TYPE]}" "${USER_PATH}"
     [[ "${SHARE_KEY}" != 'profile' ]] || setfacl -b 
"${SHARE_PATH}/${USER_DIR}"
fi

- Kees.
