参数分割出错
将/home/ldapmgt/LDAPTool.py前面部分代码改为如下即可：

-- coding: UTF-8 --
from django.conf import settings
python2/3
git clone https://github.com/python-ldap/python-ldap
pip3 install python-ldap
import sys
import ldap
import os
import configparser

config = configparser.ConfigParser()
config.read('ldap.conf')
config.sections()

hostargs = os.environ.get("LDAP_HOST")
if hostargs is None:
hostargs = config['ldap']['LDAP_HOST']
userargs = config['ldap']['LDAP_ADMIN_USER']
passwdargs = config['ldap']['LDAP_PASSWORD']
else:
userargs = os.environ.get("LDAP_ADMIN_USER")
passwdargs = os.environ.get("LDAP_PASSWORD")

userlist = userargs.split(",")
LDAP_HOST = 'ldap://%s' % hostargs # LDAP_HOST = 'ldap://172.16.140.118'
USER = '%s,%s,%s' % (userlist[0], userlist[1], userlist[2])
PASSWORD = passwdargs
BASE_DN = "%s,%s" % (userlist[1], userlist[2])

docker run命令如下：
docker run --restart=always -d -p 8000:8000 --env LDAP_HOST="IP:PORT" --env LDAP_ADMIN_USER="cn=admin,dc=baidu,dc=com" --env LDAP_PASSWORD="XXXXX" --name ldap-password lghost/ldap-password:latest
