BW SSO2 and BO

Hi experts,

we have implemented SSO2 in our BW system and its working fine. The problem is on our BO (4.1, SP3). when i start a webi report, using the scheduling, we always receive the error message:

Database error: Unable to connect to SAP BW server Incomplete logon data.. (IES 10901)

I've read 1 million notes, but till now, no luck. I saw the light after reading this treath:

but no luck. even after deploying gx64krb5.dll, in our BO server (CMC and SNC_LIB) we still have the same error.

I have this parameters on BW side:

profile:

spnego/krbspnego /usr/sap/XXX/SLL/libsapcrypto.so

spnego/krbspnego_lib /usr/sap/XXX/SLL/libsapcrypto.so
