The Local name and Name and ID authentication modes get their users from the machine that runs the Unity Version Control (UVCS) server.
Name and ID mode works the same way as Local name mode, except that it also uses the user ID.
Local name mode
In Local name mode, the UVCS server reads the names of the local users on the machine that it runs on. On startup, the server creates a list of known users, and it recalculates the list periodically.
To use this mode, configure the UVCS clients to use the local users mechanism too. The client sends the name of its signed-in user to the server. The server uses this name to check whether the user is a known user, and then makes its security calculations.
In this mode, the UVCS server:
- Retrieves the user list from the local machine users, on both Unix and Windows operating systems. On a Windows machine inside a domain, the server takes the current user if it's not a local user.
- Builds the security identifier (SEID) with the user name.
This mode relies on a correct network configuration. Use it on secure networks. For example, use it in a mixed Unix and Windows environment that depends on a Network Information Service Plus (NIS+) system. You can also use it to allow access from the internet, if the server allows only trusted clients to connect.
Name and ID mode
In Name and ID mode, the server:
- Retrieves the user list from the local machine users, on both Unix and Windows operating systems. On a Windows machine inside a domain, the server takes the current user if it's not a local user.
- Builds the SEID with the user name and ID. The ID is the user ID on Linux and the security identifier (SID) on Windows.
This mode works when all machines run the same operating system family, such as Unix with Unix, or Windows with Windows. It doesn't work between Windows and Unix without a specific authentication mechanism.
Use this mode with NIS+ systems on Unix, or with any configuration in which both systems share the same user name and ID.
