  As.... what attribute?

  We don't need to see packet captures.  PLEASE follow the documentation:

  Yes, the server doesn't store ALL attributes in SQL.  It only stores some common ones.

  To see what it's doing, read the debug output.  As the documentation says,

> What I mean by freeradius not storing, is that after a query is made from a platform to freeradius to see what ipv6 is assigned to each client and does not show it.

  I have no idea what FreeRADIUS is going, because you're not posting the debug output.

  That's not helpful.

  That's not helpful.

  That's also not helpful.

  Where else do we need to add documentation which says "PLEASE POST THE DEBUG OUTPUT" ?
