keycloak group members causes LDAP query for each individual user - keycloak

Question

I have a keycloak instance with a read only LDAP Federation. I add members to groups by searching for both GROUP_ID and USER_ID (which queries the LDAP server) and then using a 'PUT' to add the USER to the GROUP (I use python to parse the JSON):
GROUP_ID=$(curl -s -H "Authorization: bearer $ACCESS_TOKEN" \
https://${KEYCLOAK_SERVER}/auth/admin/realms/myrealm/groups|python -c '
import json,sys,os;keycloak_data=json.load(sys.stdin);
GROUP=os.environ["GROUP"]
for g in keycloak_data:
if g["name"]==GROUP:
print g["id"]
sys.exit()
')
USER_ID=$(curl -s -H "Authorization: bearer $ACCESS_TOKEN" \
https://${KEYCLOAK_SERVER}/auth/admin/realms/myrealm/users?username=$USER | python -c '
import json,sys,os;keycloak_data=json.load(sys.stdin)
USERID=os.environ["USER"]
for c in keycloak_data:
if c["attributes"]["LDAP_ID"][0]==USERID:
print c["id"]
sys.exit()
')
echo "Adding $USER to $GROUP GROUP_ID=$GROUP_ID USER_ID=$USER_ID"
curl -s -X PUT -H "Authorization: bearer $ACCESS_TOKEN" \
https://${KEYCLOAK_SERVER}/auth/admin/realms/myrealm/users/$USER_ID/groups/$GROUP_ID
Above works great. But when I want to get a list of the members in that group it queries LDAP for every user (which can take a long time if there are over 100 users in a group)
curl -s -H "Authorization: bearer $ACCESS_TOKEN" \
https://${KEYCLOAK_SERVER}/auth/admin/realms/myrealm/groups/$GROUP_ID/members
Any way to query the group membership without triggering an LDAP query for every member of the group? I have already tried changing the LDAP Cache settings under the LDAP Federation and doesn't seem to help.
I just want to know (quickly) which users are in a given keycloak group.
