The DS logs onto the Link Server in two cases: when it needs to register its IP-address with the dDNS Service (dDNS Service Registration (DD) setting = 1 (enabled)), or when the DS needs to communicate through the Link Service ( current Link Service Login (TL) [setting /parameter ] = 1 (enabled)).

When LS Auto-registration is set to 1 (enabled) the DS will attempt to register on the Link Server if, during login process, the DS is rejected and the reason for this rejection is that this DS is not yet registered (i.e. Link Server does not recognize Owner Name (ON) and  Device Name (DN) of this DS). Auto-registration is convenient because it allows the user to avoid manual editing of the list of client Device Servers on the Link Server.

WARNING! Auto-registration process involves sending DS password (defined by the Password (PW) setting ) to the Link Server. In this particular case the password is sent "unprotected" (as is) which constitutes a potential security vulnerability.
