Connection Properties

Use this page to specify the security settings to be used with this Directory Server:
Enabled
Check this to specify that the directory server will use a TLS connection.
TLS Port
The port the directory server will use for TLS connections.
Use Custom Certificates
If TLS is enabled, check this option and specify the paths for root certificates, server certificate, key file, and passphrase. In addition, the MF_ROOT_CERT environment variable will need to be set to the root-certificates file path.
Certificate File
Specifies the absolute path to the certificate file (.pem). If multiple certificates are used, separate the paths with a semicolon ';'.
Keyfile
Specifies the absolute path to the keyfile (.pem).
Keyfile Password
The password for the keyfile specify it here. If multiple keyfiles are used, separate the passwords with four colons '::::'.
Note: You can use the Micro Focus Vault Facility to store a secret for the certificate and keyfile pass phrases. This takes the following form:
mfsecret:configuration-name:secret-path

or:

mfsecret::secret-path

or:

mfsecret:secret-path

Advanced

Certificate Password
If the certificate is locked with a password, specify it here. If multiple certificates are used, then separate the passwords with two colons '::'.
Honor Server Cipher List
By default, the Honor Server Cipher List is checked. This forces clients to use the protocols and cipher suites specified in order of their priority.
Protocols
The list of TLS protocols to be used, in order of precedence. Each specified protocol is preceded by one of the following operators:
!
Exclude: Permanently exclude the protocol and ignore any subsequent attempt to add the protocol back in.
+
Add: Add the protocol to the existing collection.
-
Delete: Delete the protocol from the existing collection. For example, to only use TLS1.1 and TLS1.2, type:
-ALL+TLS1.1+TLS1.2
Note: The Protocols field now supports TLS1.3.
Cipher Suites
Specifies the priority of cipher suites to be used. The cipher suite priority is formed using a combination of keywords and keyword modifiers for a space-separated string:
!
Exclude: Permanently exclude the cipher suite and ignore any subsequent attempt to add the cipher suite back in.
+
Add: Add the cipher suite to the end of the collection.
-
Delete: Delete the cipher suite from the existing collection. By default, the following cipher suite list is used:
kEECDH+ECDSA kEECDH kEDH HIGH MEDIUM +3DES +SHA !RC4 !aNULL
!eNULL !LOW !MD5 !EXP
Diffie-Hellman Minimum Group Size
Specifies the size in bits of the modulus length of the Diffie-Hellman group:
  • Default
  • 512 bit
  • 1024 bit
  • 2048 bit
  • 4096 bit
Note: Micro Focus recommends a minimum modulus size of 2048 bits.
Key Exchange Cipher Groups
The key exchange cipher groups to be used, separated by semicolons ';'. For example:
secp521r1;secp384r1;prime256v1;secp256k1;secp224r1;secp224k1;prime192v1
