Specifies the user name that the ActiveTransfer Agent instance uses to connect to ActiveTransfer Server.To list multiple user names, use comma as the separator.

When an agent attempts to connect to ActiveTransfer Server, ActiveTransfer Server allows the connection only if the agent's user name is registered in this parameter. If the user name is not listed, ActiveTransfer Server rejects the connection and records the failed connection as invalid.

For example: mft.agent.user=FS_agent1,FS_agent2,FS_agent6
