Description Brendan Shephard 2019-07-15 22:39:19 UTC 
Description of problem:
When using Keystone with a LDAP backend, we are seeing a traceback when it tries to call ldap.initialize(url, bytes_mode=False)

Full traceback is below, but the error is:
initialize() got an unexpected keyword argument 'bytes_mode': TypeError: initialize() got an unexpected keyword argument 'bytes_mode'

We can see that ldap.initialize() is being called with bytes_mode=false, which seems to not be included in the version of python-ldap that we're shipping with this container.

https://github.com/openstack/keystone/blob/c8904b8679d2aca12b69828e36cc8f6881e83373/keystone/identity/backends/ldap/common.py#L523

Version-Release number of selected component (if applicable):
openstack-keystone:14.0-107

How reproducible:
100%

Steps to Reproduce:
1. Deploy Overcloud with the keystone:14.0-107 container
2. Configure LDAP backend
3. Try to use an LDAP account

Actual results:

Expected results:
No traceback

Additional info:
If you just remove bytes_mode=false from the ldap.initialize(url, bytes_mode=False), it works fine.
