1. A terminal single sign-on (SSO) configuration method for an enterprise mobile management (EMM) system, comprising: establishing a connection between a configuration system and an application service system, wherein the application service system refers to an application program installed on a mobile terminal associated with the EMM system, and the configuration system includes at least a hardware processor and a memory; receiving in real time, by the hardware processor of the configuration system, a user interface for authentication from the application service system; generating, by the hardware processor of the configuration system, interface elements corresponding to input controls in the user interface received from the application service system in real time, wherein each interface element generated by the configuration system corresponds to a tag of an input control and current coordinates indicating a location of the input control presented in the user interface for authentication of the application program; sequentially transmitting, by the hardware processor of the configuration system, operation information and login parameters of the interface elements from the configuration system to the application service system, wherein the operation information includes a selection instruction generated when a first interface element is chosen by the configuration system, and first current coordinates of a first input control in the user interface that is corresponded to the first interface element; sequentially recording, by the hardware processor of the configuration system, a plurality of operations on the input controls in the user interface according to the operation information and the login parameters of the corresponding interface elements, wherein the plurality of operations completes an authentication process for the application service system; generating, by the hardware processor of the configuration system, a recorded script containing the plurality of operations and the login parameters of the interface elements; associating, by the hardware processor of the configuration system, a VPN (virtual private network) login information with the recorded script; uploading, by the hardware processor of the configuration system, the VPN login information and the associated recorded script to a server and wherein when the application service system is launched next time on the mobile terminal, the application service system automatically obtains the recorded script associated with the VPN login information from the server, and automatically replays the plurality of operations to complete the authentication process.
