Issue/Introduction

We have a working Azure Entra Rest connector.

When we explore and correlate with <150 accounts, it works fine. Now when we are testing with over 500 accounts, it fails with the following error.

Environment

Release : 14.5.1
Component : CA Identity Manager

Cause

From the logs, we found out the HTTP request GET is going to Email authentication.
2025-05-09 16:31:36,684 227485 [ApacheDS Worker-thread-38] Azure_Entra_test_tenant (RESTResourceClient.java:122) DEBUG  - HTTP request GET https://graph.microsoft.com/v1.0/users?%24top=100&%24select=onPremisesSamAccountName%2CuserPrincipalName%2CauthenticationEmail%2Cid HTTP/1.1

In the Azure endpoint settings, we identified an EmailAddresses attribute mapping.

Resolution

The issue is resolved after removing the EmailAddresses attribute mapping from the Azure endpoint settings.
