I wonder if someone (for whatever reason) has renamed Domain Admins ?

Create a script 'get_admins.sh'

Containing this:

#!/bin/bash

DC=$1
PASS=$2
DOM=$3

DOMSID=$(ldbsearch -U Administrator --password="$PASS" -H ldap://"$DC"; \
         "(&(objectclass=domain)(name=$DOM))" objectSid | grep objectSid | \
         awk '{print $NF}')

ldbsearch -U Administrator --password="$PASS" -H ldap://"$DC"; \
"(objectSid=${DOMSID}-512)"

exit 0

Run it like this: 

bash ./get_admins.sh DC PASSWORD WORKGROUP

Replace:
DC with your DC's hostname

PASSWORD with your Administrator password

WORKGROUP with your lowercase workgroup name

If the SID-512 exists, it will display the object for that objectSid.
