# Free IAM - Free Identity and Access Management.

**Free IAM** is a flexible and open identity and access management system designed for interoperability, extensibility, and simplicity.
It provides clean APIs, powerful abstractions, and deep integration with common identity schemata and directory services.

## LDAP Client Library

FreeIAM offers both a asynchronous and synchronous LDAP client library for Python via `freeiam.ldap`, supporting the full range of client features.
For usage examples and detailed API documentation, please refer to the [official documentation](https://docs.freeiam.org/).

```python
import asyncio

from freeiam import ldap


async def main():
    async with ldap.Connection('ldap://localhost:389', timeout=30) as conn:
        # TLS
        conn.set_tls(ca_certfile='/path/to/ca.crt', require_cert=TLSRequireCert.Hard)
        await conn.start_tls()

        # authenticate
        await conn.bind('cn=admin,dc=freeiam,dc=org', 'iamfree')

        # search for DN and attrs
        for entry in await conn.search(search_base, Scope.Subtree, '(&(uid=*)(objectClass=person))'):
            print(entry.dn, entry.attr)

        # search iterative for DN and attrs
        async for entry in conn.search_iter(search_base, Scope.Subtree, '(&(uid=*)(objectClass=person))'):
            print(entry.dn, entry.attr)

        # search for DN
        async for entry in conn.search_dn(search_base, Scope.Subtree, '(&(uid=*)(objectClass=person))'):
            print(entry.dn)

        # search paginated via SimplePagedResult
        async for entry in conn.search_paged(
            search_base,
            Scope.Subtree,
            '(&(uid=*)(objectClass=person))',
            page_size=10,
        ):
            print(entry.dn, entry.attr, entry.page)

        # search paginated via VirtualListView + ServerSideSorting
        async for entry in conn.search_paginated(
            search_base,
            Scope.Subtree,
            '(&(uid=*)(objectClass=person))',
            page_size=10,
            sorting=[('uid', 'caseIgnoreOrderingMatch', False)]
        ):
            print(entry.dn, entry.attr, entry.page)

        # get a certain object, and use its attributes
        obj = await conn.get('uid=max.mustermann,dc=freeiam,dc=org')
        print(obj.dn, obj.attr)
        print(obj.attr['cn'])

        # get a attribute of an object
        cn = await conn.get_attr('uid=max.mustermann,dc=freeiam,dc=org', 'commonName')
        print(cn)


asyncio.run(main())
```

The same API exists synchronously:
```python
from freeiam import ldap


with ldap.Connection('ldap://localhost:389', timeout=30) as conn:
    # TLS
    conn.set_tls(ca_certfile='/path/to/ca.crt', require_cert=TLSRequireCert.Hard)
    conn.start_tls()

    # authenticate
    conn.bind('cn=admin,dc=freeiam,dc=org', 'iamfree')

    # search for DN and attrs
    for entry in conn.search(search_base, Scope.Subtree, '(&(uid=*)(objectClass=person))'):
        print(entry.dn, entry.attr)
```

## Test Coverage

The project currently maintains 100% test coverage, ensuring that all code paths are exercised by automated tests.
This helps guarantee reliability, correctness, and ease of future maintenance.

## LDAP client benchmarks
Current benchmarks indicate that the synchronous non-iterable methods offer the best performance.
The benchmark suite compares FreeIAM (`freeiam.ldap`) against Python-LDAP (`ldap`), LDAP3 (`ldap3`), and Bonsai (`bonsai`).

Please note this is a work in progress (WIP) and the benchmark coverage and accuracy will be improved over time.
