LDAP client library
A pure-Rust LDAP client library using the Tokio stack.
Version notices
The 0.11 branch has had a belated but important dependency
upgrade: the nom
parser combinator crate, both in the lber
support library
and ldap3
proper. This should be an implementation detail invisible to the user,
and the parsers have a battery of tests, but the version was nevertheless bumped up
out of abundance of caution. There are no functional differences between 0.10.6
and 0.11.3.
Starting with 0.10.3, there is cross-platform Kerberos/GSSAPI support if compiled with the gssapi feature. This feature enables the use of integrated Windows authentication in Active Directory domains. See the description of the feature in this README for the details of compile-time requirements.
The 0.11 branch is actively developed. Bug fixes will be ported to 0.10.x. The 0.9 branch is hence retired.
Documentation
API reference:
There is an LDAP introduction for those still getting their bearings in the LDAP world.
Miscellaneous notes
The library is client-only. One cannot make an LDAP server or a proxy with it. It supports only version 3 of the protocol over connection-oriented transports.
There is no built-in support for connection pooling, automatic fallback or reconnections.
Usage
Add this to your Cargo.toml
:
[dependencies.ldap3]
version = "0.11.3"
The library can be used either synchronously or asynchronously. The aim is to offer essentially the same call interface for both flavors, with the necessary differences in interaction and return values according to the nature of I/O.
Examples
The following two examples perform exactly the same operation and should produce identical
results. They should be run against the example server in the data
subdirectory of the crate source.
Other sample programs expecting the same server setup can be found in the examples
subdirectory.
Synchronous search
use ldap3::{LdapConn, Scope, SearchEntry};
use ldap3::result::Result;
fn main() -> Result<()> {
let mut ldap = LdapConn::new("ldap://localhost:2389")?;
let (rs, _res) = ldap.search(
"ou=Places,dc=example,dc=org",
Scope::Subtree,
"(&(objectClass=locality)(l=ma*))",
vec!["l"]
)?.success()?;
for entry in rs {
println!("{:?}", SearchEntry::construct(entry));
}
Ok(ldap.unbind()?)
}
Asynchronous search
use ldap3::{LdapConnAsync, Scope, SearchEntry};
use ldap3::result::Result;
#[tokio::main]
async fn main() -> Result<()> {
let (conn, mut ldap) = LdapConnAsync::new("ldap://localhost:2389").await?;
ldap3::drive!(conn);
let (rs, _res) = ldap.search(
"ou=Places,dc=example,dc=org",
Scope::Subtree,
"(&(objectClass=locality)(l=ma*))",
vec!["l"]
).await?.success()?;
for entry in rs {
println!("{:?}", SearchEntry::construct(entry));
}
Ok(ldap.unbind().await?)
}
Compile-time features
The following features are available at compile time:
-
sync (enabled by default): Synchronous API support.
-
gssapi (disabled by default): Kerberos/GSSAPI support. On Windows, system support crates and SDK libraries are used. Elsewhere, the feature needs Clang and its development libraries (for
bindgen
), as well as the Kerberos development libraries. On Debian/Ubuntu, that meansclang-N
,libclang-N-dev
andlibkrb5-dev
. It should be clear from these requirements that GSSAPI support uses FFI to C libraries; you should consider the security implications of this fact.For usage notes and caveats, see the documentation for
Ldap::sasl_gssapi_bind()
in the API reference. -
tls (enabled by default): TLS support, backed by the
native-tls
crate, which uses a platform-specific TLS backend. This is an alias for tls-native. -
tls-rustls (disabled by default): TLS support, backed by the Rustls library.
Without any features, only plain TCP connections (and Unix domain sockets on Unix-like platforms) are available. For TLS support, tls and tls-rustls are mutually exclusive: choosing both will produce a compile-time error.
