NTLM not working on CE 7.2.1 https://liferay.dev/c/message_boards/find_thread?p_l_id=119785294&threadId=121177064 2026-04-05T21:18:20Z 2026-04-05T21:18:20Z Zsigmond Rab https://liferay.dev/c/message_boards/find_message?p_l_id=119785294&messageId=121180389 2021-10-04T06:53:32Z 2021-10-04T06:53:31Z

<p>Hi David,</p> <p>As I can see it fails on connecting to the NTLM server. Have you tried to debug what's happening? I could do that only.</p> <p>Is there any error on the NTLM side? That may help also.</p> <p>Regards,</p> <p>Zsigmond</p>

<p>I'm setting the NTLM authentication for my organization, to avoid entering the username and password for each user (automatic login through NTLM). The connection with LDAP is correct, the same occurs with the NTLM settings. Taking a look at the logs I found the following error:</p> <pre> <code class="language-java">[NtlmFilter:304] Unable to perform NTLM authentication java.lang.NullPointerException at
