Re: [Samba] ntfs user mappings?




I decided to continue trying the ldap route as well

littlehex2int()
{
 hex=$1
 hex_chunk=$(echo ${hex}|cut -c$2-$3)
 little=$(echo ${hex_chunk}|awk '{print
substr($0,7,2)substr($0,5,2)substr($0,3,2)substr($0,1,2)}')
 echo "ibase=16; ${little}" | bc
}

base64_to_sid()
{
OBJECTSID="$1"
hex=$(echo ${OBJECTSID}|base64 -d|od -A n -x -w28 --endian=big|sed 's/
//g'|awk '{print toupper($1)}')
hex_chunk=$(echo ${hex}|cut -c1-2);
rev=$(echo "ibase=16; ${hex_chunk}" | bc)
hex_chunk=$(echo ${hex}|cut -c3-4)
dashes=$(echo "ibase=16; ${hex_chunk}" | bc)
hex_chunk=$(echo ${hex}|cut -c5-16)
notsure=$(echo "ibase=16; ${hex_chunk}" | bc)
nonuniq=$(littlehex2int ${hex} 17 24)
issuer1=$(littlehex2int ${hex} 25 32)
issuer2=$(littlehex2int ${hex} 33 40)
issuer3=$(littlehex2int ${hex} 41 48)
uid=$(littlehex2int ${hex} 49 57)
echo "S-${rev}-${dashes}-${nonuniq}-${issuer1}-${issuer2}-${issuer3}-${uid}"
}
