Hi Maciek,

For login/password auth, buildbot uses twisted authentication framework.
You should not derive AuthBase, but rather something like this:
class HTPasswdAuth(TwistedICredAuthBase):

def __init__(self, **kwargs):
[DigestCredentialFactory(b"md5", b"buildbot"),

and MyCredentialChecker should be a ICredentialsChecker like this reference

More info on twisted cred framework:
