PyMongo uses md5 hash for authentification and md5 is not safe to use while FIPS mode is on. Using PyMongo authentification will result in failures with FIPS mode.


From pymongo/auth.py:

try:
    import hashlib
    _MD5 = hashlib.md5
except ImportError: # for Python < 2.5
    import md5
    _MD5 = md5.new
....

def __password_digest(username, password):

....

    md5hash = _MD5()
    data = "%s:mongo:%s" % (username, password)
    md5hash.update(data.encode('utf-8'))
    return unicode(md5hash.hexdigest())

I do not recommend to fix this issue, changing hash function to e.g sha256 may result into backward incompatible change.
