The Plesk 9 backward compatibility prevents malfunctioning of client applications which interact with Plesk 9 through old versions of API RPC(<126.96.36.199) and hence cannot sufficiently accommodate changes in Plesk business logic. For these applications, we modified the behavior of some operations to fit new Plesk business logic. Most modifications are operation specific, some modifications are common for all operations. The common modification are as follows:
adminas a Plesk client login name. Hence, in some situations Plesk Administrator now acts like a Plesk client. We will refer to this client account as to the artificial client account. You cannot modify or remove this account.
Each operation-specific modification is described in the corresponding sub-section of the Supported Operations chapter.
