Active Directory authentication library wrapper written in C++
Authenticating users against Active Directory in Python is slow with pure Python packages. I wanted to speed up the process for saving time on both ends (server & client). It seemed trivial to implement the AD authentication in C/C++ and call it from Python.
According to my simple, unaccredited tests, the speedup was clearly observable.
Getting user details, such as, e-mail address, full name, manager, group memberships, etc... have been deliberately excluded from this wrapper because I wanted to speed up the login procedure only. The rest of the calls to AD are done asynchronously without blocking the end-user.
Last, but not least I wanted to learn about the C/C++ <-> Python interoperability while trying to write a cross-platform code.
The libAdAuth library is cross-platform (Linux + Windows) library with a single platform dependency.
To build the library, a C/C++ compiler will be required on each build system.
The built binaries and/or libraries are put in the out directory.
The recommended compiler is g++ 5.4.0 or newer.
To be able to link against libldap, it must be installed first.
To install libldap on Debian/Ubuntu, execute the following command:
sudo apt-get install libldap2-dev
The recommended compiler is g++ (clang).
To be able to link against libldap, it must be installed first.
To install libldap on macOS with brew, execute the following command:
brew install openldap
The recommended compiler is MSVC 2017 or newer.
To be able to link against winldap, it must be installed first.
To install winldap, the Windows 10 SDK must be installed.
The libAdAuth library is compiled to a Shared Library on all platforms.
- Linux:
libAdAuth.so - macOS:
libAdAuth.dylib - Windows:
libAdAuth.dll
The libAdAuth library exposes a single C function interface in Release build and an optional debug function called foo in Debug build mode.
// Release Build
int auth(char *username, char *password, char *host, char *domain, int *port);
// Debug Build only [ with -DDEBUG ]
int foo(); // "Hello from foo()"For a Python reference implementation for each platform, see the following files:
