Bo Mobile Authentication Problem

i use MDS 4.1.4 and bb simulator 9530

bo is the same place with mds and bb simulator.

mds and bo in the same server:192.168.1.66 local ip.and machine name is botest(mobile server is in the same place too)

VAS-cluster config:

i added:

[comm]

[comm $ mds]

HOST_PORT =192.168.1.66:8888

VAS-server.config:

i added:

[comm $ external]

ENABLED=mds

[comm $ external $ mds]

EXTERNAL_HOSTNAME=BOTEST

CLIENT_TYPE=mds

VMS-server.config:

i added:

[comm $ external]

ENABLED=mds

[comm $ external $ mds]

EXTERNAL_HOSTNAME=BOTEST

CLIENT_TYPE=mds

in this situation i connect to the cms with a bb simulator..but in a real bb says to me " authentication login...."

what is the problem?

thanks in advance.
