Samba Folks, Here's my situation.... I have a linux system, Redhat ES3, Samba 3.0.2. I have the linux box configured to use LDAP authentication to our Corporate LDAP servers, which are Sun I believe. What I need to do now, is setup Samba to use NTLM2, and hit the LDAP server for authentication. I've been working on this for a couple of days now and can't seem to get anywhere. I can get it to work with encrypted passwords turned off and ntlm2 off. But that will violate our corporate security policies. Any help would be great. Thanks, William C.
