SSO sends wrong password

[piwi]

Hi,

I'm testing Alfresco 4.0b. I've configured ldap-ad for synchronisation (working) and passthru for SSO authentication with our AD.
Passthru is working if I login using the prompt, when I'm not logged on with my computer on the DC. But if I'm logged on with my AD credentials Alfresco SSO sends wrong credentials (wrong password) to the DC and I get a 'failed' back. I've tested this with wireshark.

Someone recognises this problem? Maybe a policy setting?

Do you allow NTLMv1 on your clients? This is needed for SSO through NTLM (passthru) to work.

You also might want to check your IE settings, making sure that you allow automatic login and that the server is in the Intranet zone.
