Activating the User Authentication¶

Single System and Replica Set Primary¶

The user authentication of MongoDB is disabled by default. Activate the user authentication to enhance the security.

Open a PowerShell (Administrator) and change to the following directory:
```
C:\Program Files\SEAL Systems\seal-mongodb
```
Execute the following script:
```
.\secure-mongo.ps1
```

Secondary Members of the Replica Set¶

If you run PLOSSYS 5 in a cluster, execute the above step on the replica set primary. Then execute the following steps on any secondary member of the replica set:

Copy the key file created by secure-mongo.ps1 on the replica set primary
```
C:\ProgramData\SEAL Systems\config\mongod.keyfile
```
into the following directory on your current member of the replica set:
```
C:\ProgramData\SEAL Systems\config\
```

Add the following lines to the C:\ProgramData\SEAL Systems\config\mongod.conf file:

security:
  authorization: enabled
  keyFile: C:\ProgramData\SEAL Systems\config\mongod.keyfile

Restart MongoDB:
```
seal-mongodb
```
Proceed with step 1 on the next member of the replica set.
