v0.11.3, 2023-06-08

  • Handle servers which return zero for send_max_size in the GSSAPI negotiation. Zero is effectively treated as unlimited, to avoid artificial low limits. This is a reworked fix for #97, which adjusted the size to 256 KiB.

  • Update rustls and tokio-rustls.

  • Fix type visibility in lber (#102).

  • Make lber compile on 32-bit architectures, which broke because the updated parser had an implicit assumption that usize is 64 bits. Fixes #99.

v0.11.2, 2023-06-08

See the list for 0.11.3, no documentation was updated.

v0.11.1, 2023-01-04

  • Add an LDAP introductory document (LDAP-primer.md).

  • Update nom to 7.x.

  • Add Ldap::get_peer_certificate() and its sync counterpart, which return the server certificate for the connection if present.

v0.10.5, 2022-05-12

  • Fix SASL EXTERNAL binds (#83). An empty authzId must be encoded as such in the Bind request, not left out.

v0.10.4, 2022-04-26

  • Check the send buffer size before GSSAPI wrapping, if any. (Not expected to matter in realistic usage.)

  • Deprecate ldap_str_unescape() in favor of ldap_unescape(). The latter name should have been used from the start.

  • Minor documentation fixes.

v0.10.3, 2022-03-30

  • Add support for cross-platform Kerberos/GSSAPI authentication and SASL security layer. Authentication over TLS connections will provide the "tls-server-end-point" channel binding token to the server to maximize Active Directory interoperability.

    GSSAPI support is behind the compile-time "gssapi" feature which is off by default, since it requires FFI to C libraries with a checkered security history.

v0.10.2, 2022-02-26

  • Use the native root certificate store for rustls cert verification. The store is initialized once and cloned for each new connection.

v0.10.1, 2022-02-25

  • Fix rustls build. The API changed substantially between 0.19 and 0.20.

v0.10.0, 2022-02-25

  • Update dependencies.

  • Change to Edition 2021.

  • [breaking change] Enable passing either owned or borrowed attribute lists to the search function. This adds another generic parameter to the Adapter trait, which infects all dependent structs. Type inference should take care of most cases, but creating Adapter dynamic instances must be modified. The same goes for custom Adapter implementations.

v0.9.3, 2021-04-02

  • Tweak the socket shutdown code for Unbind to a) actually perform a graceful socket shutdown, b) ignore errors after successfully writing the Unbind op packet, since from that point the connection is finished anyway.

  • Add the is_closed() method to Ldap and LdapConn. This is a quick check whether the underlying socket has been closed, actually checking the connection usability requires a roundtrip with an operation like WhoAmI.

v0.9.2, 2021-01-11

  • SEO: update Cargo.toml description to use "LDAP" insetead of "LDAPv3", in hope that the crate won't be relegated to the second page of search results for "ldap" on crates.io.

v0.9.1/v0.8.3/v0.7.4, 2021-01-05

  • Fix id/value splitting in extension parsing, limiting the number of elements to at most 2. (The bug can be worked around by percent-encoding the equals sign.)

v0.9.0/v0.8.2/v0.7.3, 2020-12-30

  • The new main branch, 0.9.x, ported to Tokio 1.0.

  • The lber crate was bumped to 0.3.0 because its dependency, the bytes crate, went to 1.0 along with Tokio. (0.9.x only.)

  • Two new connection establishment functions accept a url::Url reference instead of &str. They exist to avoid re-parsing the URL if its parameters were extracted earlier.

  • LDAP URL parsing added. The syntax specified by RFC 4516 is mapped into the LdapUrlParams struct. An LDAP URL must be parsed by url::Url::parse() before extracting its components.

  • Matched Values control support added (#65).

v0.8.1/v0.7.2, 2020-11-24

  • Timeouts are honored in Search operations (#63).

  • Password Modify extended operation support added (#60).

v0.8.0, 2020-10-19

Port to Tokio 0.3 and the refresh of a couple of dependencies. Otherwise, there are no functional differences compared to 0.7.1.

v0.7.1, 2020-06-11

This version completely overhauls the internals of the library by porting it to Tokio 0.2 and async/await. This makes the asynchronous interface one big breaking change, so it makes no sense to enumerate the differences. The synchronous interface proved rather more stable, but there are a couple of breaking changes there, too.

  • Rustls can be used as an alternative to native-tls for TLS support.

  • The search adapter framework lets user-supplied code control the execution of a Search operation and transform returned entries and result codes. Two adapters are included in the crate: EntriesOnly, which filters out referrals and intermediate messages from the stream, and PagedResults, which uses the control of the same name and automatically applies it to a Search operation until the full result set is retrieved.

  • [breaking change]: ResultEntry now has public components, where the second is the set of controls associated with the entry. This is necessary in order to process all elements of the content synchronization protocol. The struct is marked as non-exhaustive to help ensure forward compatibility.

  • [breaking change]: The LdapConn struct now must be mutable, since all methods require &mut self.

  • [breaking change]: The error part of the functions and methods that return Result is now an instance of LdapError. There is a blanket automatic conversion to io::Error to make the change less problematic for applications.

  • [breaking change]: Streaming Search returns raw entries, without trying to parse referrals or intermediate messages. The EntriesOnly search adapter can be used to restore the earlier behavior. Ordinary Search drops intermediate messages and collects all referrals in the result vector.

  • [breaking change]: There is no autopage search option for automatically applying the Paged Results control to a Search. Use the PagedResults search adapter instead.

  • LdapConn is now Send, meaning that it's usable in connection pool managers such as r2d2.

v0.6.1, 2018-10-16

  • A number of dependencies have been updated to avoid deprecation warnings when compiling.

  • Skipping all TLS checks is simplified, being abstracted by native-tls.

  • TLS connections can be made to an IP address.

v0.6.0, 2018-03-25

  • Searches can be automatically paged by using SearchOptions::autopage().

  • LdapConnSettings::set_no_tls_verify() can be used to request skipping certificate hostname checks. If supported by the platform TLS backend, this may be combined with a custom connector which can skip all TLS checks.

  • SASL EXTERNAL binds also work when authenticating with TLS client certificates, so Ldap::sasl_external_bind() and its sync adapter are no longer limited to Unix-like systems.

  • It's possible to set a custom hostname resolver with LdapConnSettings::set_resolver(). The intent is to enable asynchronous resolution when dealing with async connections.

  • [breaking change] Ldap::{connect,connect_ssl,connect_unix} signatures have changed to accept an LdapConnSettings argument.

  • [breaking change] Ldap::connect_ssl() is additionally changed to accept the hostname for TLS checks instead of finding it out itself. This is done to centralize address resolution.

  • [breaking change] LdapConnBuilder has been removed. Connection parameters can now be set via LdapConnSettings and passed to connection establishment routines via with_settings(), both sync and async.

  • StartTLS is now supported.

  • Add and Modify operations now accept arbitrary binary attribute values (#20).

v0.5.1, 2017-08-21

  • An LDAP connection can be constructed with a pre-built TLS connector using LdapConnBuilder::with_tls_connector() (#11). This function is not publicly documented, to avoid fixing the API. The intent is to allow connections which need additional connector configuration, such as those to a server using a self-signed certificate.

  • The function ldap3::dn_escape() is provided to escape RDN values when constructing a DN (#13).

v0.5.0, 2017-07-20

Changes are listed approximately in reverse chronological order. Since they are so numerous for this release, and many are breaking changes, please read them carefully.

  • Assertion, Pre- and Post-Read controls are implemented in-tree.

  • Ldap::with_controls() can also accept a single control, without the need to construct a vector.

  • [breaking change] Searches return a vector of ResultEntry elements, so the internal ASN.1 type is hidden. This changes the signature of SearchEntry::construct().

  • Control and exop implementations don't depend on internal traits and structs, enabling independent third-party development.

  • [breaking change] Exop and control handling is streamlined, but old parsing methods don't work any more. The signatures of Ldap::extended(), LdapConn::extended(), Ldap::with_controls() and LdapConn::with_controls() have changed.

  • LdapResult implements success(), which returns the structure itself if rc is zero, or an error if it's not. There's also non_error(), which also considers the value 10 (referral) as successful.

  • [breaking change] Compare returns CompareResult, a newtype of LdapResult which implements the equals() method, transforming compareFalse/compareTrue rc values to a boolean.

  • [breaking change] Non-streaming search returns a wrapper type, SearchResult. The success() method can be invoked on a value of this type, destructuring it to an anonymous tuple of a entry vector and result struct, and propagating error cases, as determined by LdapResult.rc, upward.

  • [breaking change] Async and sync search APIs are now aligned. Ldap::search() returns a future of the result entry vector, which it internally collects; what used to be Ldap::search() is now named Ldap::streaming_search().

  • [breaking change] Ldap::streaming_search() returns a future of just a SearchStream, instead of a tuple. The result receiver must be extracted from the stream instance with SearchStream::get_result_rx(). The receiver is also simplified, and now retrieves just the LdapResult.

  • [breaking change] LdapResult contains the response controls.

  • [breaking change] Ldap::abandon() accepts the msgid, not id. It's not meant to be called directly any more.

  • [breaking change] SearchStream::id() has been removed.

  • [breaking change] LdapConn::abandon() has been removed.

  • [breaking change] LdapResult.rc is now u32 (was: u8).

  • [breaking change] Ldap::connect() and Ldap::connect_ssl() have an additional parameter, an optional connection timeout.

  • Timeout support, which can be used both synchronously and asynchronously. Timeouts can be specified both for connection establishment and individual LDAP operations. For the first case, a connection must be constructed through LdapConnBuilder.

  • The function ldap3::ldap_escape() is provided to escape search literals when constructing a search filter.

v0.4.4, 2017-05-29

  • Fix Windows build (#7).

  • Make TLS support optional (#6).

  • Reorganize build-time features: "tls" includes TLS support, and is on by default, while "minimal" excludes both TLS and Unix domain sockets.

v0.4.3, 2017-05-12

  • Documentation for controls and extended operations.

  • Minimal documentation for the ASN.1 subsystem.

  • Proxy Authorization control has been implemented.

v0.4.2, 2017-05-08

  • Documentation update.

  • Support for Unix domain sockets on Unix-like systems.

  • Support for SASL EXTERNAL binds, also limited to Unix-like systems for the time being, since they can only work on Unix domain socket connections (we can't use TLS client certs yet.)

v0.4.1, 2017-05-06

  • Fix integer parsing (#1). Active Directory length encoding triggered this bug.

  • Fix the crash when parsing binary attributes (#2). The SearchEntry struct now has an additional field bin_attrs, containing all attributes which had at least one value that couldn't be converted into a String. Since it's possible that otherwise unconstrained binary attributes have values that can be successfully converted into Strings in a particular result set, the presence of such attributes should be checked for both in attrs and in bin_attrs.

    This is technically a breaking change, but since it isn't expected that any SearchEntry instance would've been created manually, the version stays at 0.4.x.

v0.4.0, 2017-05-03

First published version.
