How to modify ou? in python-ldap - Codes Helper

problem description

when using python-ldap, there is a problem that you need to modify ou. Looking at the official python-ldap documentation, you can find that the function of rename_s () can solve this problem, but the ldap version used on the server does not support this operation.
thought that you can use search () to find user information, delete the user information under the original ou, and then use add () to add the user information to the new ou, but when you encounter a problem,: search () cannot find the attribute userpassword.

the environmental background of the problems and what methods you have tried

openldap version: openldap-2.4.44-15.el7_5.x86_64
python version: 2.7.5

        result = self.ldap_obj.rename_s(dn, newrdn, newsuperior, delold)
        print result
    except ldap.LDAPError, error_message:

    else:
        authority_str = ""
        if (dn_list[1].strip() == "ou=Users") and (newsup_list[0].strip() == "ou=Admins"):
            authority_str = "TRUE"
        elif (dn_list[1].strip() == "ou=Admins") and (newsup_list[0].strip() == "ou=Users"):

        b, result = self.modify_user(dn,  attr_list)
        return b, result
