 Python 2.6
 ----------
 
-Tempest can be run with Python 2.6 however the unit tests and the gate
-currently only run with Python 2.7, so there are no guarantees about the state
-of tempest when running with Python 2.6. Additionally, to enable testr to work
-with tempest using python 2.6 the discover module from the unittest-ext
-project has to be patched to switch the unittest.TestSuite to use
-unittest2.TestSuite instead. See:
-
-https://code.google.com/p/unittest-ext/issues/detail?id=79
+Starting in the kilo release the OpenStack services dropped all support for
+python 2.6. This change has been mirrored in tempest, starting after the
+tempest-2 tag. This means that proposed changes to tempest which only fix
+python 2.6 compatibility will be rejected, and moving forward more features not
+present in python 2.6 will be used. If you're running you're OpenStack services
+on an earlier release with python 2.6 you can easily run tempest against it
+from a remote system running python 2.7. (or deploy a cloud guest in your cloud
+that has python 2.7)

+Tempest Configuration Guide
+===========================
+
+Auth/Credentials
+----------------
+
+Tempest currently has 2 different ways in configuration to provide credentials
+to use when running tempest. One is a traditional set of configuration options
+in the tempest.conf file. These options are in the identity section and let you
+specify a regular user, a global admin user, and a alternate user set of
+credentials. (which consist of a username, password, and project/tenant name)
+These options should be clearly labelled in the sample config file in the
+identity section.
+
+The other method to provide credentials is using the accounts.yaml file. This
+file is used to specify an arbitrary number of users available to run tests
+with. You can specify the location of the file in the
+auth section in the tempest.conf file. To see the specific format used in
+the file please refer to the accounts.yaml.sample file included in tempest.
+Currently users that are specified in the accounts.yaml file are assumed to
+have the same set of roles which can be used for executing all the tests you
+are running. This will be addressed in the future, but is a current limitation.
+Eventually the config options for providing credentials to tempest will be
+deprecated and removed in favor of the accounts.yaml file.
+
+Credential Provider Mechanisms
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Tempest currently also has 3 different internal methods for providing
+authentication to tests. Tenant isolation, locking test accounts, and
+non-locking test accounts. Depending on which one is in use the configuration
+of tempest is slightly different.
+
+Tenant Isolation
+""""""""""""""""
+Tenant isolation was originally create to enable running tempest in parallel.
+For each test class it creates a unique set of user credentials to use for the
+tests in the class. It can create up to 3 sets of username, password, and
+tenant/project names for a primary user, an admin user, and an alternate user.
+To enable and use tenant isolation you only need to configure 2 things:
+
+ #. A set of admin credentials with permissions to create users and
+    tenants/projects. This is specified in the identity section with the
+    admin_username, admin_tenant_name, and admin_password options
+ #. To enable tenant_isolation in the auth section with the
+    allow_tenant_isolation option.
+
+
+Locking Test Accounts
+"""""""""""""""""""""
+For a long time using tenant isolation was the only method available if you
+wanted to enable parallel execution of tempest tests. However this was
+insufficient for certain use cases because of the admin credentials requirement
+to create the credential sets on demand. To get around that the accounts.yaml
+file was introduced and with that a new internal credential provider to enable
+using the list of credentials instead of creating them on demand. With locking
+test accounts each test class will reserve a set of credentials from the
+accounts.yaml before executing any of its tests so that each class is isolated
+like in tenant isolation.
+
+Currently, this mechanism has some limitations, first only non-admin users with
+the same role set can be used at one time. The second limitation is around
+networking, locking test accounts will only work with a single flat network as
+the default for each tenant/project. If another network configuration is used
+in your cloud you might face unexpected failures.
+
+To enable and use locking test accounts you need do a few things:
+
+ #. Enable the locking test account provider with the
+    locking_credentials_provider option in the auth section
+ #. Create a accounts.yaml file which contains the set of pre-existing
+    credentials to use for testing. To make sure you don't have a credentials
+    starvation issue when running in parallel make sure you have at least 2
+    times the number of parallel workers you are using to execute tempest
+    available in the file.
+ #. Provide tempest with the location of you accounts.yaml file with the
+    test_accounts_file option in the auth section
+
+
+Non-locking test accounts
+"""""""""""""""""""""""""
+When tempest was refactored to allow for locking test accounts, the original
+non-tenant isolated case was converted to support the new accounts.yaml file.
+This mechanism is the non-locking test accounts provider. It only makes sense
+to use it if parallel execution isn't needed. If the role restrictions were too
+limiting with the locking accounts provider and tenant isolation is not wanted
+then you can use the non-locking test accounts credential provider without the
+accounts.yaml file. This is also the currently the default configuration for
+tempest, since it doesn't require elevated permissions or the extra file.
+
+To use the non-locking test accounts provider you have 2 ways to configure it.
+First you can specify the sets of credentials in the configuration file like
+detailed above with following 9 options in the identity section:
+
+ #. username
+ #. password
+ #. tenant_name
+ #. admin_username
+ #. admin_password
+ #. admin_tenant_name
+ #. alt_username
+ #. alt_password
+ #. alt_tenant_name
+
+You should use this if you need to specify credentials with different roles.
+(i.e. you want to use admin credentials) However, this isn't a requirement for
+its usage.
+
+You also can use the accounts.yaml file to specify the credentials used for
+testing. This will just allocate them serially so you only need to provide
+a pair of credentials. Do note that all the restrictions associated with
+locking test accounts applies to using the accounts.yaml file this way too.
+The procedure for doing this is very similar to with the locking accounts
+provider just don't set the locking_credentials_provider to true and you
+only should need a single pair of credentials.
