Title:
  Non-Latin charated in base DN results in backend initialization
  failure: ERROR 'ascii' codec can't decode byte 0xd0 in position 94:
  ordinal not in range(128)

Status in OpenStack keystone charm:
  Fix Released
Status in OpenStack Keystone LDAP integration:
  Invalid
Status in OpenStack Identity (keystone):
  Invalid

Bug description:
  == Steps to reproduce
  Deploy a keystone-ldap charm and provide a following ldap-user DN: "CN=openstack openstack,OU=Технологические пользователи,OU=Users,DC=corp,DC=com"

  == Problem statement

  cloud: focal-ussuri, latest stable charms

  The project I'm working on has an LDAP integration, and I've been
  given a following base DN: "CN=openstack openstack,OU=Технологические
  пользователи,OU=Users,DC=corp,DC=com", which I'm supplying as a ldap-
  user option of keystone-ldap charm.

  If I'll remove a non-latin OU part - then Keystone is trying to
  authenticate, but failing, complaining about invalid bind credentials.
  Then, if I'll return the "OU=Технологические пользователи" part back,
  the following occurs in keystone.log:

  Apparently, it's trying to read the domain config and something goes
  wrong at this step (as there's even no authentication attempt being
  made).
