Initial Sign On to Infoview

I am upgrading to BO XI 3.1 using Single Sign On with Active Directory. The initial sign on to Infoview takes about 5 minutes. I am not receiving any errors, however in the trace logs I found the following warnings :

.\TrustedPrincipal.cpp:109: TraceLog message 1

Thanks for any help.
