Hello, David,
group values in your logs are BASE64-encoded binary AD-groups SIDs.
You can try to decode them by a simple perl script sid-reader.pl (see below):
echo
AQUAAAAAAAUVAAAACkdDGG1JBGW2KqEShhgBAA== | base64 -d | perl sid-reader.pl
And finally convert SID to a group name:
wbinfo -s S-01-5-21-407062282-1694779757-312552118-71814
Kind regards,
Ankor
