Authenicate fails with IndexError exception with LDAP and user_enabled_emulation

[Johan]

I am running latest keystone from git (82ded4a) and am using keystone configured with the LDAP and using user_enabled_emulation.

I get the exception "IndexError: string index out of range" when trying to authenticate.

My research suggests that it's the commit that fixed bug 1340041 that introduced this bug. Everything works when I revert the commit that fixed that.

The problem is the following:

in line 1672 (keystone/common/ldap/core.py) for the patch for the above bug the ldap.dn.str2dn array gets converted to a string which causes naming_rdn to contain "[" and then I get an exception on line 1675 because the string has length one.

    Fix parsing of emulated enabled DN

    If a non-default emulated enabled DN is specified in configuration,
    the DN structure returned from python-ldap is incorrectly converted
    to a string. This leads to an index error when we attempt to extract
    the RDN attribute and value.

    This patch removes the incorrect string conversion and instead does
    the proper conversion on the RDN strings that we extract.

    Ensure sql upgrade tests can run with non-sqlite databases.

    This patch fixes the issues that were preventing the running of
    live sql upgrade tests (either by running test_sql_upgrade directly
    or via test_sql_livetest), namely:

    - Dropping the tables that were in existence before the current
      scope of migration in an order that is FK friendly
    - Fixing an issue where the tables were being dropped in the
      wrong order in the downgrade of federation
    - Ensuring we don't hold sessions open over upgrade/downgrade
      steps in our test methods

    Limitations:

    - This patch has not been tested with DB2

    Validates controller methods exist when specified

    It was possible to specify an invalid controller method in a router.
    This will not cause an error until runtime. This change catches the
    error much earlier in the application lifecycle. In fact with this
    change errors should not be able to pass unit tests even if there is
    no specific test for the behavior.

    Fixes an error deleting an endpoint group project

    Deleting a endpoint group project fails because the router specifies
    a controller method that doesn't exist. This returns a 500 error to
    the user for what should be a successful operation.

    Fix tests comparing tokens

    There were tests that verified that the PKI token body could be
    encrypted with CMS and compared to the token ID in the response.
    This test isn't safe because the token body may be different than
    the token encrypted with CMS since the order of items in the dict
    can change.
