A major issue regarding ADAM/AD LDS is around the creation of Service Connection Points and why they are needed. Let’s take a further look into this topic and uncover the mystery of this object.
What are Service Connection Points? Service Connection Points (SCPs) are objects in Active Directory that hold information about services. Services can publish information about their existence by creating serviceConnectionPoint objects in Active Directory. Client applications use this information to find and connect to instances of the service. ADAM/AD LDS is no exception to this. The serviceConnectionPoint object class is derived from the connectionPoint class. ServiceConnectionPoints in ADAM/AD LDS will contain some key attribute information that is needed for client application discovery. The table below lists the contents of the serviceConnectionPoint object attributes. You can also find this information by using ADSIEDIT.MSC and viewing the properties of the child object of the computer that the ADAM/AD LDS instance is installed.
For example, Exchange 2007 uses SCPs to advertise autodiscover service information. The serviceBindingInformation attribute of this object is updated during setup with the autodiscover service URL.
