HTTP Authentication using NTLM failed

leonardo_m — Thu, 05 Jun 2025 06:50:50 GMT

Dear NetApp Users,

I have a problem with the Data ONTAP built in HTTP Web Server.

The authentication is not working properly. For example: Once that the user was authenticated he can access any folder independent of the share permission configuration, or be, the user can access folders which they wouldn´t.

The following message is shown:

Wed Jul 13 11:15:34 BRT [HTTPPool00:warning]: HTTP Authentication from XXX.XXX.XXX.XXX using NTLM failed

I use the CIFS Authentication which works without problems.

Some usefull information:

NETFAS 2020

NetApp Release 7.3.2

Domain type: Windows 2003

Authentication type: Active Directory

Security Style: NTFS Only

*The domain server firewall is disabled for now.

Share permissions only come into effect when you access data through that share. Have you tried NTFS permissions?

Yes, it worked fine with the NTFS permissions.

I thought that DATA ONTAP Share Configurations should works with the HTTP authentication, however in my case, the HTTP authentication only worked properly with the NTFS permissions.

Thank you!
