I can confirm this bug when upgrading a Lenny system to Squeeze. Before the upgrade (with version 5.4.8 from backports): NT_STATUS_OK: Success (0x0). After the upgrade to 3.5.6: NT_STATUS_INVALID_HANDLE: Invalid handle (0xc0000008).
We rely on ntlm_auth to authenticate RADIUS clients. This bug will prevent us from upgrading to Squeeze until it is resolved. I agree with Alex King that this should be marked grave. Thanks, Daniel Bakken
