Horde Auth
==========

[](#horde-auth)

Authentication and user management library for the Horde framework.

Provides a clean, interface-based architecture for credential validation, transparent authentication, user directory queries, user lifecycle management, and password operations across multiple backends.

New in this version
-------------------

[](#new-in-this-version)

The main interface has been split into several capability oriented interface. Drivers no longer pseudo implement capabilities they don't really have but only expose those interfaces they really provide, i.e. certificate authentication does no longer provide an interface to list users or change passwords. Authentication results are now objects instead of booleans.

Installation
------------

[](#installation)

```
composer require horde/auth
```
