I dug a bit more and found this in the logs:








(keystone.common.wsgi): 2014-01-27 19:07:13,851 WARNING The action you have requested has not been implemented.
Despite basing my (super simple) code on the SQL or LDAP backends, I must be doing something wrong.
-->> I've placed my backend code in /usr/share/pyshared/keystone/identity/backends/nicira.py or /usr/share/pyshared/keystone/common/nicira.py
-->> I DO see the "my authenticate module loaded" in the log
I would appreciate any help in figuring out what I'm missing. Thanks!

Dolph, I appreciate the response and pointing me in the right direction.
Here's what I have so far:
<imports here>







CONF = config.CONF
LOG = logging.getLogger(__name__)


class Identity(identity.Driver):
    def __init__(self):
        super(Identity, self).__init__()
        LOG.debug('My authentication module loaded')


    def authenticate(self, user_id, password, domain_scope=None):
        LOG.debug('in authenticate method')
When I request a user-list via the python-keystoneclient, we never make it into the authenticate method (as is evident by the missing debug log).
Any thoughts on why I'm not hitting this method?

_check_password() is a private/internal API, so we make no guarantees about it's stability. Instead, override the public authenticate() method with something like this:
    def authenticate(self, user_id, password, domain_scope=None):

        if user_id in SPECIAL_LIST_OF_USERS:           # compare against value from keystone.conf           pass        else:            return super(CustomIdentityDriver, self).authenticate(user_id, password, domain_scope)

I'm looking to create a simple Identity driver that will look at usernames. A small number of specific users should be authenticated by looking at a hard-coded password in keystone.conf, while any other users should fall back to LDAP authentication.


I based my original driver on what's found here:
http://waipeng.wordpress.com/2013/09/30/openstack-ldap-authentication/


As can be seen in the github code (https://raw.github.com/waipeng/keystone/8c18917558bebbded0f9c588f08a84b0ea33d9ae/keystone/identity/backends/ldapauth.py), there's a _check_password() method which is supposedly called at some point.


I've based my driver on this ldapauth.py file, and created an Identity class which subclasses sql.Identity. Here's what I have so far:








CONF = config.CONF
LOG = logging.getLogger(__name__)


class Identity(sql.Identity):
    def __init__(self):
        super(Identity, self).__init__()
        LOG.debug('My authentication module loaded')




    def _check_password(self, password, user_ref):
        LOG.debug('Authenticating via my custom hybrid authentication')


        username = user_ref.get('name')
























        LOG.debug('Username = %s' % username)


I can see from the syslog output that we never enter the _check_password() function.

Can someone point me in the right direction regarding which function calls the identity driver? Also, what is the entry function in the identity drivers? Why wouldn't check_password() be called, as we see in the github / blog example above?


THANKS!
