Hi, I am running SAMBA 3.0.14a and having the problem described in bug 765. https://bugzilla.samba.org/show_bug.cgi?id=765 Which is: If Win2k3 policy: "Domain Controller: LDAP server signing requirements" set to "Require Signing", net ads join fails My questions: 1. If I upgrade to the latest SAMBA will it solve the problem. Meaning that "Allow StartTLS support when connecting to Windows 2003 by leaving the default setting 'ldap ssl = start_tls'" is solve this issue? 2. Other than disabling signing on the DC, is there any workaround or particular configuration on the SAMBA 3.0.14a server to overcome this problem. Cheers, Ephi
