LDAP and NTLM conflict under linux

[gianluca]

Hi everybody,
I've configured Alfresco 2.1 on my linux workstation with ntlm and ldap as mentioned in wiki and everything runs fine. I can trust users on active directory server and then import with specified job defined in job-scheduler. I have also copied the entire directory into another linux workstation and after changed configuration files according the new ip address I've tried to run the new alfresco instance.

At this time I've got an error:
"12:25:06,007 ERROR [[Catalina].[localhost].[/alfresco]] Exception starting filter Authentication Filter

This sound strange because the configuration files are the same of the alfresco instance running correctly on the first workstation.
I've tried to modify the NTLMAuthenticationFilter.java to get the value of m_authComponent.getNTLMMode(). In the first working instance the m_authComponent.getNTLMMode() return the correct value of "PASS_THROUGH" according to configuration files but in the second alfresco instance thi value is "NONE"!!!!!

Please help me!
Thanks.

Do you use a clone of your Workstation or do you have different OS

[gianluca]

Hi, I've the same OS (linux ubuntu) but in the first instance is ubuntu workstation and in the second one is ubuntu server. I've found the problem!
I must turn off the ldap authentication because it hurts to the ntlm authentication.

Thanks

To community: is there really no possibility to use ldap-Synchronisation (for users and groups) with NTLM-SSO-Autologin?

[gianluca]

Yes, you can! You must activate ntlm authentication an then ldap syncronization but without activating the ldap authentication because you have to use the ntlm and SSO.
