We have just released version 6.0.5 of the UnboundID LDAP SDK for Java. It is available for download from GitHub and SourceForge, and it is available in the Maven Central Repository. You can find the release notes at https://docs.ldap.com/ldap-sdk/docs/release-notes.html, but here’s a summary of the changes included in this version:

General Updates:

  • We fixed an issue that could occasionally cause the LDAP SDK to hide the actual cause of a StartTLS failure by using information from a second, less useful exception.

  • We fixed an issue that could cause the ldifsearch tool to display a malformed message when the first unnamed trailing argument was expected to be a search filter but could not be parsed as a valid filter.

  • We improved support for validating and comparing values using the telephone number syntax. Previously, we used a loose interpretation of the specification, which would consider any printable string (including strings without any digits) to be valid, and would only ignore spaces and hyphens when comparing values. You can now configure varying levels of strictness (either programmatically or using system properties), including requiring at least one digit or strict conformance to the X.520 specification. You can also configure it to ignore all non-digit characters when comparing values, and this is now the default behavior.

  • We fixed a bug in which the ldapcompare tool did not properly close its output file if one was configured. The output file does get automatically closed when the tool exits so it’s not an issue when running ldapcompare from the command line, but this can cause problems if the tool is invoked programmatically from another application.

  • We fixed an issue with the tool properties file created using the --generatePropertiesFile argument in command-line tools that support it. The generated properties file did not properly escape backslash, carriage return, line feed, or form feed characters.

Updates Specific to Use With the Ping Identity Directory Server:

  • We added support for encoding controls to JSON objects, and for decoding JSON objects as controls. There is a generic JSON representation that will work for any type of control (in which the value is provided as the base64-encoded representation of the raw value used in the LDAP representation of the control), but most controls provided as part of the LDAP SDK also support a more user-friendly representation in which the components of the value are represented in a nested JSON object.

  • We added client-side support for a new JSON-formatted request control that can be used to send request controls to a Ping Identity Directory Server with the controls encoded as JSON objects rather than a raw LDAP representation. We also added support for a JSON-formatted response control that can be used to receive JSON-encoded response controls from the server.

  • We updated the ldapsearch and ldapmodify command-line tools to add a --useJSONFormattedRequestControls argument that will cause any request controls to be sent using a JSON-formatted request control, and it will cause any response controls returned by the server to be embedded in a JSON-formatted response control.

  • We fixed an issue with the way that the parallel-update tool created assured replication request controls when an explicit local or remote assurance level was specified. Previously, it would only specify a minimum assurance level without specifying a maximum level, which could cause the server to use a higher assurance level than requested by the client.

  • We updated the topology registry trust manager to allow trusting a certificate chain if either the peer certificate or any of its issuers is found in the server’s topology registry. Previously, it would only trust a certificate chain if the peer certificate itself was found in the topology registry, and having an issuer certificate was not sufficient. The former behavior is still available with a configuration option.

  • We updated the topology registry trust manager to make it possible to ignore the certificate validity window for peer and issuer certificates. The validity window is still respected by default, but if the trust manager is configured to ignore it, then a certificate chain may be trusted even if the peer or an issuer certificate is expired or not yet valid.
