A ldap client library that wraps ldap3 to make it easy to use.
Adding simple_ldap as a dependency to your project:
cargo add simple-ldap
Other useful pieces you'll likely need:
cargo add url serde --features serde/derive
There are plenty more examples in the documentation!
use simple_ldap::{
    LdapClient, LdapConfig, SimpleDN,
    filter::EqFilter,
    ldap3::Scope
};
use url::Url;
use serde::Deserialize;
use serde_with::serde_as;
use serde_with::OneOrMany;
// A type for deserializing the search result into.
#[serde_as] // serde_with for multiple values
#[derive(Debug, Deserialize)]
struct User {
    pub dn: SimpleDN,
    pub uid: String,
    pub cn: String,
    pub sn: String,
    #[serde_as(as = "OneOrMany<_>")]
    pub addresses: Vec<String>,
}
#[tokio::main]
async fn main(){

        bind_password: String::from("password"),
        ldap_url: Url::parse("ldaps://localhost:1389/dc=example,dc=com").unwrap(),
        dn_attribute: None,
        connection_settings: None
    };
    let mut client = LdapClient::new(ldap_config).await.unwrap();
    let name_filter = EqFilter::from("cn".to_string(), "Sam".to_string());
    let user: User = client
        .search(
        "ou=people,dc=example,dc=com",
        Scope::OneLevel,
        &name_filter,
        vec!["dn", "cn", "sn", "uid","addresses"],
    ).await.unwrap();
