AccountManage | Account password management APP

I have a very basic question as I was watching few tutorials related to Microservices. If I am creating multiple microservices for 1 application, should I need to implement Authentication and Authorization for all microservices? For example If I have an e-commerce website and I have multiple microservices with certain endpoints for the purchase model.

1. As a user when I login to the UI, initially calling in AccountManagement microservice ( which has few functionality such Register/Login/Reset/Revoke) and then move from one feature to another which interim calls another microservice (should the next microservice read the cookie information and authenticate automatically ? Is that how it works?
2. Will my other microservices also have all features of the Account management microservice or only authenticating through Refresh token?

I am fairly new to this concept in microservices and trying to grasp as much as I can through tutorials but these questions are something I still struggle to understand properly.

I want to write a PowerShell script that takes username and password as input and then it checks if a user with those credentials exists and has admin rights.

Most of the questions or articles I have seen are about the active directory. I'm not talking about the active directory. I just want to check for a normal local machine.

I've tried this but I think this is about the active directory too.

I am trying to integrate our on-prem AD with an Azure function app. I need to be able to get users and update them.

We have both Azure AD and on-prem AD which are synced via the Azure AD Connect, which syncs only one way (from AD to AAD). So I want to update users in the on-prem AD, which will sync to the Azure AD. For this, I am using System.DirectoryServices.AccountManagement, which works fine from my local machine. However, it doesn't work in my Azure app.

We have set up a hybrid connection to the AD to have a gateway, but we haven't been able to make it work. We have also created a user which has read-rights to the domain.

Code:

I have list of uniques from column ACCOUNTMANAGER and I need to pick sorted duplicates to separate file.

Is it possible to use duplicates or something similar to pick identical column values and save them to separate lists?

Let's say ACCOUNTMANAGER contains list of names ['Jack', 'Jack', 'Dane', 'Jessica', 'Jessica', 'Jessica' ]. I would like to have jack list of all Jacks, Dane list oven if one value and list of Jessicas. How can I do this using uniques and duplicates? Here is my code:

I am creating an android project. for input validation, I created a different class and created a constructer also but I have a problem. I don't know how to get the context of that class in which I am calling that constructer.

I am relatively new to Django, but just finished creating a custom user model rather then using the base. When running createsuperuser im getting the following error stack:

File "C:\Users\adamt\AppData\Local\Programs\Python\Python38-32\lib\site-packages\django\contrib\auth\base_user.py", line 66, in save super().save(*args, **kwargs) TypeError: save() got an unexpected keyword argument 'user'

My custom model, create_user and create_superuser are:

Something strange happened. I have created the custom user model. It was working properly until today. And I have no idea what has gone wrong. When I launch the admin page to login, I see below error after I click on 'login'. I use 'email' as an username

I am developing an authentication system for User registration through Django restframework. I have followed youtube link to configure serialzers. Since the Tutor is not using class based views, So, I didn't follow that part. I have written own class based view for ListCreateAPIView.
