KeyError upon LDAPConnection instantiation

[Synforge]

When connecting to an LDAP server on a remote CentOS machine I receive the following error:

>>> import ldapom
>>> c = ldapom.LDAPConnection(uri='ldap://auth-1.example.io', base='dc=example,dc=io', bind_dn='cn=Manager,dc=example,dc=io', bind_password='password')

Thank you for your bug report. It looks like one of the attributes on your LDAP server doesn't have a defined SYNTAX. To better debug the issue, could you insert the line print('\n'.join(list(attribute_type_definitions))) into ldapom/connection.py at line 156 and try to instantiate the connection again?

   attribute_type_definitions = map(compat._decode_utf8,
             result[0][1][compat._encode_utf8("attributeTypes")])

 + print('\n'.join(list(attribute_type_definitions)))
 +
   self._attribute_types_by_name = attribute.build_attribute_types(
             attribute_type_definitions)

It should print a list of attribute types that it retrieved from the server. You can post the output here or send it to my personal email (leonh@ndreke.de). Thanks!
