How to: Troubleshoot sign-in errors using Azure Active Directory reports
The sign-ins report in Azure Active Directory (Azure AD) enables you to find answers to questions around managing access to the applications in your organization, including:
- What is the sign-in pattern of a user?
- How many users have users signed in over a week?
- What’s the status of these sign-ins?
In addition, the sign-ins report can also help you troubleshoot sign-in failures for users in your organization. In this guide, you learn how to isolate a sign-in failure in the sign-ins report, and use it to understand the root cause of the failure.
- An Azure AD tenant with a premium (P1/P2) license. See Getting started with Azure Active Directory Premium to upgrade your Azure Active Directory edition.
- A user, who is in the global administrator, security administrator, security reader, or reports reader role for the tenant. In addition, any user can access their own sign-ins.
Troubleshoot sign-in errors using the sign-ins report
Navigate to the Azure portal and select your directory.
Select Azure Active Directory and select Sign-ins from the Monitoring section.
Use the provided filters to narrow down the failure, either by the username or object identifier, application name or date. In addition, select Failure from the Status drop-down to display only the failed sign-ins.
Identify the failed sign-in you want to investigate. Select it to open up the other details window with more information about the failed sign-in. Note down the Sign-in error code and Failure reason.
You can also find this information in the Troubleshooting and support tab in the details window.
The failure reason describes the error. For example, in the above scenario, the failure reason is Invalid username or password or Invalid on-premises username or password. The fix is to simply sign-in again with the correct username and password.
You can get additional information, including ideas for remediation, by searching for the error code, 50126 in this example, in the sign-ins error codes reference.
If all else fails, or the issue persists despite taking the recommended course of action, open a support ticket following the steps in the Troubleshooting and support tab.
