  You will post a question ONCE, and only once.  Replying to other
threads with your question is rude.

  Your configuration is possible.

1) FreeRADIUS stores all accounting data in the "detail" file.  Or, in
SQL.  See the raddb/sql/.../dialup.conf file.  They're text for a

2) yes, you can use AD to do groups.  Configure AD as an LDAP server,
and use LDAP-Group for comparisons.  There are examples.
