  [1] DS Lint Error: DSELE0001
  --------------------------------------------------------------------------------
  Severity: MEDIUM
  Affects:
   -- cn=encryption,cn=config
  
  Details:
  -----------
  This Directory Server may not be using strong TLS protocol versions. TLS1.0 is known to
  have a number of issues with the protocol. Please see:
  
  https://tools.ietf.org/html/rfc7457
  
  It is advised you set this value to the maximum possible.
  
  Resolution:
  -----------
  There are two options for setting the TLS minimum version allowed.  You,
  can set "sslVersionMin" in "cn=encryption,cn=config" to a version greater than "TLS1.0"
  You can also use 'dsconf' to set this value.  Here is an example:
  
      # dsconf slapd-instance_name security set --tls-protocol-min=TLS1.2
  
  You must restart the Directory Server for this change to take effect.
  
  Or, you can set the system wide crypto policy to FUTURE which will use a higher TLS
  minimum version, but doing this affects the entire system:
  
      # update-crypto-policies --set FUTURE
  
  
  \===== End Of Report (1 Issue found) =====
