Preventing automatic creation of users

Warning

By default, Helix server creates a new user whenever a previously unknown user invokes any command that can update the repository or its metadata. When executed by a nonexistent user, most Perforce commands cause a user to be created. You can control this behavior by setting the dm.user.noautocreate configurable with the p4 configure command. For greatest security, we recommend that only the Helix server superuser be allowed to create new users:

$ p4 configure set dm.user.noautocreate=2
