Initialize a domain structure properly. Excerpt from wb_init_domain.c: /* * Initialize a domain: * * - With schannel credentials, try to open the SMB connection with the machine * creds. Fall back to anonymous. * * - If we have schannel creds, do the auth2 and open the schannel'ed netlogon * pipe. * * - Open LSA. If we have machine creds, try to open with ntlmssp. Fall back * to schannel and then to anon bind. * * - With queryinfopolicy, verify that we're talking to the right domain * * A bit complex, but with all the combinations I think it's the best we can * get. NT4, W2k3SP1 and W2k all have different combinations, but in the end we * have a signed&sealed lsa connection on all of them. * * Is this overkill? In particular the authenticated SMB connection seems a * bit overkill, given that we do schannel for netlogon and ntlmssp for * lsa later on w2k3, the others don't do this anyway. */ Thanks to Jeremy for his detective work, and to the Samba4 team for providing such a great infrastructure. Next step is to connect to SAM. Do it via LDAP if we can, fall back to samr with all we have. Volker
