groupname value

[J E H A N Z A I B]

Hi folks,

I think this has been talked about a couple of times in the past but i can
not see the reply with the best way to achieve it so pardon me if i am
duplicating the issue/concerns.

radacct.groupname is empty obviously there is no default query for it.
It's not coming in the radaccouting so i don't think we can do in the
accounting query either. have someone already done it ? can you please
guide us how to do  it? I think writing down step by step will be helpful
for the community.

Our system information:
FreeRADIUS Version 3.0.13
5.5.56-MariaDB MariaDB Server
CentOS Linux release 7.4

Thanks
