When using the web services sdk and trying to access the SecurityInfo2 off of an infoobject, it always returns null.
This occurs when you do not set the security options to true off of the getoptions object.
You need to make sure that you set
boGetOptions.IncludeSecurity = true;
boGetOptions.IncludeSecuritySpecified = true;
for the GetOptions object and pass it to the biplatform object you are using to query.
boResponseHolder = boBIPlatform.Get(query, boGetOptions);
