If you find that when certain older clients or servers attempt to connect
- with a :class:`SSLContext` created by this function that they get an
- error stating "Protocol or cipher suite mismatch", it may be that they
- only support SSL3.0 which this function excludes using the
- :data:`OP_NO_SSLv3`. SSL3.0 has problematic security due to a number of
- poor implementations and it's reliance on MD5 within the protocol. If you
- wish to continue to use this function but still allow SSL 3.0 connections
- you can re-enable them using::
