To start the password file harmonization the link "User Management", found under the menu item
"Management", must be selected (see figure below). When selected the user interface for the ac-
count management appears. The last tab (called "Harmonization") in the user interface is used for
the password file harmonization by authenticate all available CMU's. Due to the sensible information
in the authentication the following notice has to be considered.
The web pages of this functionality require secure HTTPS access. It is not possible to open the
web pages with standard HTTP access.

Before a harmonization of the password file is possible, the authentication of the administration user
must be provided by the user for all detected CMU's. The provided authentications are compared
with authentications requested from the other CMU modules. Only if all authentications are correct
the password file can be harmonized and distributed to the other CMU modules.
The next figure shows an example for an RTU with 2 CMU's. For each detected CMU the rack and
slow address is shown. Furthermore there are input fields for user name, password and a button
to authenticate each CMU. A CMU is authenticated by typing a user account with administrator
permissions and selecting the button "Authenticate". A correct authenticated CMU is identified by
the check box on the right side.
