adal

Note: This library is already replaced by MSAL Python, available here: https://pypi.org/project/msal/ .ADAL Python remains available here as a legacy. The ADAL for Python library makes it easy for python application to authenticate to Azure Active Directory (AAD) in order to access AAD protected web resources.

AI interpretation — verify before relying

AI-generated interpretation of the package facts above; every digit, version, license, or vulnerability id it cites is grounded in the facts already shown on this page

ADAL for Python authenticates applications with Azure Active Directory to obtain tokens for accessing Azure AD-protected resources. This library is now superseded by MSAL for Python and receives no new feature development.

Low install friction with four stable runtime dependencies (PyJWT, requests, python-dateutil, cryptography). However, the package is abandoned as of 2021-04-05 with no active maintenance; the repository is archived and the maintainers explicitly recommend migrating to MSAL for Python for new projects.

MIT license permits broad use, modification, and distribution with minimal restrictions, suitable for most commercial and open-source contexts.

Usage

pip install adal==1.2.7

from adal import AuthenticationContext

context = AuthenticationContext('https://login.microsoftonline.com/{tenant_id}')
token = context.acquire_token_with_username_password(
    'https://graph.microsoft.com', username, password
)

Requires valid Azure AD tenant ID and credentials; this library is deprecated and Microsoft recommends MSAL for Python for new applications.

Verdict: ADAL is a mature, permissively licensed library with low install friction, but it is abandoned and explicitly superseded by MSAL for Python. Use only for maintaining existing applications; do not adopt for new projects. No known security vulnerabilities are recorded, but the lack of maintenance means future issues will not be addressed.

Needs verification

Whether the 1956 days since last release (2021-04-05) reflects the true end-of-life date or if maintenance has resumed
Compatibility of ADAL 1.2.7 with Python versions beyond 3.6, given classifier claims only through 3.6
Real-world adoption rate and whether the top_1000 tier reflects legacy usage or active new deployments
