These files are vendored from passlib 1.7.4
(https://pypi.org/project/passlib/) and are covered by the notices below
rather than by anyldap's own LICENSE:

    src/anyldap/samba/_passlib/_md4.py from passlib/crypto/_md4.py
    src/anyldap/samba/_passlib/des.py  from passlib/crypto/des.py
    test/test_vendored_md4.py          from passlib/tests/test_crypto_builtin_md4.py
    test/test_vendored_des.py          from passlib/tests/test_crypto_des.py

They have been modified: their Python 2 compatibility shims are replaced,
the tests are adapted to pytest, and all four are formatted by anyldap's
linters. The second notice below applies only to des.py, whose routines
passlib in turn derived from Aki Yoshida's UnixCrypt.java.
