@imod ,
Welcome to the Microsoft Q&A forum.
Based on my understanding above, I see that aad token is successfully received Information Successfully Received AAD Credential Token. User: ******@yyyy.xx
but the credentials are not getting fetched from KeyChain.
You can try below mentioned steps and see if they help resolve the issue.
- If possible, can you reinstall VPN client and import the latest XML config file again and see if that helps resolve the issue. You can follow this guide for implementation.
- As this can be an issue related to KeyChain you can also engage Apple support to further troubleshoot this issue.
Another approach here will be to create a support ticket for this issue as a support engineer can take a look at the backend logs and help pinpoint the issue. If you do not have a support plan, you can refer to my private comment above.
Hope this helps! Please let me know if you have any additional questions. Thank you!
