ldap2pg: UnicodeDecodeError when using sync_map.ldap and Python 2.7.13

The following ldap2pg.yml is working fine with Python 2.7.13 on Debian 9.4 (see attached ldap2pg.success.log for details):

verbose: on

ldap:
  uri: ldap://localhost:389/

postgres:
  managed_roles_query: |
    SELECT rolname
    FROM pg_catalog.pg_roles
    WHERE
        (rolsuper IS FALSE)
        AND (rolname NOT IN ('xxx-admin'))
    ORDER BY 1;

sync_map:
- roles:
  - name: role1
    options: NOLOGIN
  - name: role2
    option: NOLOGIN

But whenever I add ldap entries to the sync_map:

sync_map:
- roles:
  - name: role1
    options: NOLOGIN
  - name: role2
    option: NOLOGIN
- ldap:
    base: dc=cxptc,dc=org
  role:
    name_attribute: sAMAccountName
    options: LOGIN

I get this:

The logs for successful and failed runs are attached: ldap2pg.fail.log ldap2pg.success.log

My config is: ldap2pg 4.10 from git master, psycopg2 2.6.2, python-ldap 2.4.28 and Python 2.7.13 on Debian 9.4. LDAP (Samba AD DC 4.8.2-debian) and PostgreSQL (9.6.7) are on the same host and anonymous LDAP searches are enabled.

I tried with Python 3.5.3 but encountered another issue: #224
