37 * complete a domain join, when joining to a AD domain:
38 * 1.) connect and bind to the DRSUAPI pipe
39 * 2.) do a DsCrackNames() to find the machine account dn
41 * 4.) do an ldap search to find the "msDS-KeyVersionNumber" of the machine account
42 * 5.) set the servicePrincipalName's of the machine account via LDAP, (maybe we should use DsWriteAccountSpn()...)
43 * 6.) do a DsCrackNames() to find the domain dn
44 * 7.) find out Site specific stuff, look at libnet_JoinSite() for details
