A couple of questions PoPToP+FreeRadius+IAS

[Marxy]

My configuration is:

[poptop pptpd & pppd]----[freeradius]-----[Microsoft IAS]----[ADS]

pptpd is 1.3.3
pppd is 2.4.4
freeradius is 1.1.3

Clients go from internet, make auth via MS IAS, but accounting does
freeradius.
All seems good. Clients go OK. Auth and accounting seems OK too.

But, I have couple of questions 

1. Accounting of Calling-station-id returns only first 4 characters of
user's IP address.
I noticed that if some user enters using his remote IP like 77.122.215.143
the record of his Calling-Station-Id would be 

        Calling-Station-Id = "1.77"

which are first 4 symbols of IP address in back order.

What's goin' wrong? I suppose that calling-station-id should be whole IP
address.

2. Radius does not understand some attributes from client.
a) Jan 14 12:37:14 shata pppd[25046]: rc_avpair_gen: received unknown
attribute 25 of length 30:
0x333B04270000013700010A00001701C735C490B2116B000000000000014C
b) Jan 11 22:29:02 shata pppd[19185]: RADIUS: wrong service type 4 for
user21

But I know that these are

VALUE        Service-Type                    Dialback-Framed-User    4

and

ATTRIBUTE  MS-CHAP2-Response                       25      octets

as they are written in the dictionary file.
For the first case users can not login. Radius refuse them by wrong service
type.
In second case users login OK but I what to know why there is error anyway.

What is wrong here?

Thank for replies,
