BO 4.1 sdk c# secLDAP geting null value

Hi,

I am doing an enhancement of sdk developed utility.

Below code is snippet of dll file created which is used by utility and works fine existing setup.

While debugging on below code , I get null for ldapObj.  but InfoObj has "{secLDAP}" when a quick watch is done.

InfoObject is not typecast to secLDAP.

Bo 4.1 sdks; .net 4.0,x86 targer platform, using Visual Studion 2013 and code is C#.

string query = "SELECT TOP 1 * FROM CI_SYSTEMOBJECTS WHERE SI_NAME = 'secLDAP'";

                infoObjects = infoStore.Query(query);

                if (infoObjects.ResultCount > 0)
                {
                 
                    CrystalDecisions.Enterprise.InfoObject infoObj = infoObjects[1];
                    CrystalDecisions.Enterprise.Auth.secLDAP ldapObj = infoObj as CrystalDecisions.Enterprise.Auth.secLDAP);
                    ldap.Properties["SI_UPDATE_TS"].Value = DateTime.Now;
                  
                    infoStore.Commit(infoObjects);
                }

Thanks,

Regards,
