# Authorization and Fault-Tolerant Servers

EMS authorization interacts with fault tolerance. If `authorization` is enabled and the two EMS Servers are configured for fault tolerance, then both servers in a fault-tolerant pair must be configured.

The following files have to be updated:

- The `tibemsd.conf` file for each server must have the same server name and password (the server and password parameters must be the same on each server).
- The user name and password in the `users.conf` file for each server must match the values of the server and password parameters in the tibemsd.conf file.

Note: If the two EMS Servers are not sharing a users.conf file, make sure that you create a user with the same name as the EMS Server, and set the user's password with the value of the "server" password.

For example, you have two EMS Servers (Server 1 and Server 2) that are named "EMS-SERVER" and are to use a password of "mySecret", but which do not share a users.conf file. To set the user names and passwords, start the EMS Administration Tool on each server, as described in EMS Administration Tool, and do the following.

From the active (Server 1), enter:

       set server password=mySecret
       create user EMS-SERVER password=mySecret

From the standby (Server 2), enter:

       set server password=mySecret
       create user EMS-SERVER password=mySecret

From the active (Server 1), enter:

       set server authorization=enabled

From the standby (Server 2), enter:

       set server authorization=enabled
