如何在Django中拆分ldap参数

LDAP_CONFIG = {
    'SERVER_URI': 'ldap://ldap.example.com',
    'BASE_DN': 'dc=example,dc=com',
    'USER_DN_TEMPLATE': 'uid=%(user)s,ou=users,dc=example,dc=com',
    'GROUP_SEARCH_BASE': 'ou=groups,dc=example,dc=com',
    'GROUP_TYPE': 'posixGroup',
    'GROUP_OBJECT_CLASS': 'groupOfNames',
    'GROUP_TYPE_FLAG': 'GID',
}

import ldap
from django_auth_ldap.config import LDAPSearch, GroupOfNamesType

AUTH_LDAP_SERVER_URI = LDAP_CONFIG['SERVER_URI']
AUTH_LDAP_BIND_DN = ''
AUTH_LDAP_BIND_PASSWORD = ''
AUTH_LDAP_USER_SEARCH = LDAPSearch(
    LDAP_CONFIG['BASE_DN'],
    ldap.SCOPE_SUBTREE,
    LDAP_CONFIG['USER_DN_TEMPLATE']
)
AUTH_LDAP_GROUP_SEARCH = LDAPSearch(
    LDAP_CONFIG['GROUP_SEARCH_BASE'],
    ldap.SCOPE_SUBTREE,
    '(objectClass={})'.format(LDAP_CONFIG['GROUP_OBJECT_CLASS'])
)
AUTH_LDAP_GROUP_TYPE = GroupOfNamesType(name_attr=LDAP_CONFIG['GROUP_TYPE_FLAG'])
