1. A method for converting authentication-tokens, comprising: receiving a command-execution request from a first application, wherein the command-execution request specifies a command to be executed by a second application; verifying a first authentication-token included with the command-execution request; translating the first authentication-token to a form associated with the second application to produce a second authentication-token; modifying the command-execution request by replacing the first authentication-token with the second authentication-token to create a modified command-execution request; and sending the modified command-execution request to the second application.
