Logging the matched SQL-Group

[Brian Candler]

When rlm_sql is running through each of a user's groups, the value
%{SQL-Group} is set for each iteration. However it's cleared at the end.

I would like to be able to capture the value of SQL-Group which was
successfully matched (if any), so that I can log it in rlm_sql_log.

Is there a straightforward way of doing this? Because I can't see one right
now...

Thanks,

Brian.
