Editing Guidelines

  • To set a value, you must manually add this property to the TDGSS configuration file for the needed mechanisms. See Editing Configuration Files.
  • Before you configure this property, use the command openssl ciphers -v ALL to obtain a list of ciphers available from OpenSSL.
  • If you configure this property, use a colon-separated list of ciphers, in preference order. The list must be in accordance with OpenSSL documentation.
  • You can specify HIGH, MEDIUM, LOW, EXPORT, or EXPORT40 (instead of cipher names) to indicate a strength range for acceptable ciphers.
  • You can specify TLSv1, SSLv3, or SSLv2 to indicate a cipher suite.
  • If you decide to configure this property, edit the value for all mechanisms that have the AuthorizationSupported property set to yes.
  • Edit this property on the database and the Unity server, if used. Also see Coordinating Mechanism Property Values for Unity.
