To Configure the Pass Phrase in a File

You can configure the pass phrases that a listener requires in the mf-server.dat file. When you start the listener, it retrieves the passphrases from the file, and you do not need to configure them manually.

The mf-server.dat file is in the %ProgramFiles(x86)%\Micro Focus\Enterprise Developer\bin or \bin64 directory by default.

Open the mf-server.dat file in a text editor.
In the file, add the following lines:
```
[Listener-name/SSL/passphrases]
certificate=certificate passphrase
keyfile=keyfile passphrase
```
where:
- Listener-name is the name of the listener.
- certificate passphrase is the certificate's passphrase.
- keyfile passphrase is the keyfile's passphrase.
Save the file and start the listener. The listener retrieves the passphrases from the file and starts.

Note:

The pass phrases appear in plain text in the mf-server.dat file. For security purposes, you should make this file readable only by the user account (or accounts) under which the enterprise server is started. That would normally be the account under which Micro Focus Directory Server (MFDS) runs (typically LOCAL_SYSTEM) and the accounts of any users who run casstart from the command line.
