  It has nothing to do with AD.  Read the debug log.  Honestly, this
isn't hard:

[sql]   expand: %{User-Name} -> host/NetEng-D410.NE.LOCAL
[sql] sql_set_user escaped user --> 'host/NetEng-D410.NE.LOCAL'
rlm_sql (sql): Ignoring unconnected handle 4..
rlm_sql (sql): Ignoring unconnected handle 3..
rlm_sql (sql): Ignoring unconnected handle 2..
rlm_sql (sql): Ignoring unconnected handle 1..
rlm_sql (sql): Ignoring unconnected handle 0..
rlm_sql (sql): There are no DB handles to use! skipped 5, tried to connect 0
++[sql] returns fail
Invalid user: [host/NetEng-D410.NE.LOCAL/<via Auth-Type = EAP>] (from
client 0.0.0.0/0 port 3 cli 00-14-22-fd-dd-98)

  Your SQL server is down.  Fix it.
