Allowing Micetro Web Interface to Log In to Other Central Servers
===================================================================

By default, the Micetro UI and API only allow connecting to a single Micetro Central server, determined during the first login to Micetro after installation.

If you want to allow users to specify a custom Central server to connect to, follow the instructions below.

Windows
-------

1. Edit the ``preferences.cfg`` file for the Micetro Web Services located at ``c:\\ProgramData\\Men and Mice\\Web Services\\preferences.cfg``. Add the following XML tag:

  .. code-block::

    <LockToDefaultServer value="0" />

2. Restart the Micetro Web Services Windows service.

3. After that, a "Server" field will appear on the Micetro login page, and the "serverName" field in the API Login command will be honored.

Linux
-----

1. Log into the server hosting Micetro.

2. Edit the ``preferences.cfg`` file for the Micetro Web Services (``/var/mmsuite/web_services/preferences.cfg``). Add the following XML tag:

  .. code-block::

    <LockToDefaultServer value="0" />

3. Restart the ``mmws`` service:

  .. code-block:: bash

    systemctl restart mmws

4. After that, a :guides:`Server` field will appear on the Micetro login page, and the :guilabel:`serverName` field in the API Login command will be honored.
