Where are the radmind config files stored? On the server or on the clients?

The config file is stored on the server, at

/var/radmind/config

by default.

The command file is stored on the server and has a name defined by the radmind administrator, like lab.K or staff.K, and stored on the server, at /var/radmind/command. When updating the client, you use the tool ktcheck to download the clients managed file system defined in the server command file (i.e. lab.K or staff.K), which is renamed to command.K and, is stored on the client, at

/var/radmind/client

by default.
