 [About AZURE-NEW-APP-CLIENT-ID and AZURE-NEW-APP-SECRET](https://community.microfocus.com/t5/Identity-Manager-Tips/Creating-the-application-Client-ID-and-Client-Secret-from/ta-p/1776619). The redirect URL is your Wekan root-url+_oauth/oidc like this: https://boards.example.com/_oauth/oidc

+### If Azure Active Directory login does not work
+
+Check that your CLIENT_SECRET = AZURE-NEW-APP-SECRET has not expired. If it has, delete old secret, and add new secret.
+Add it like this, and also check that your Azure Directory ID is in server URL:
+
+```
+sudo snap set wekan oauth2-secret='AZURE-CLIENT-SECRET'
+
+sudo snap set wekan oauth2-server-url='https://login.microsoftonline.com/AZURE_DIRECTORY_ID'

+Instead, use O365 at upcoming Wekan v5.38 or newer.

 ### Mailjet: getaddrinfo ENOTFOUND
 
 With Wekan Snap and Mailjet, if you get getaddrinfo ENOTFOUND error when you try to send a test email from within Wekan, it can be something with networking for the snap. Fix can be found in [Ubuntu DNS resolution issue affecting other snap packages](https://github.com/nextcloud/nextcloud-snap/issues/881). Thanks to [peterk for info](https://github.com/wekan/wekan/issues/3184#issuecomment-699669350).
