Disclosed are various embodiments for exporting user accounts and associated information from a directory service for a local computing environment to the authentication service of a remote computing environment. A list of user accounts including usernames and other associated data is selected after querying the directory service. The selection of user accounts is then analyzed to make sure that a minimum set of data has been selected. Subsequently, the user account data is written to file, which can then be either programmatically uploaded or manually uploaded. In certain embodiments of the present disclosure, user account information may be directly exported to an authentication service through a network connection without the intermediate step of first writing the data to file.
