- * do a domain join using DCERPC/SAMR calls
- * 1. connect to the SAMR pipe of users domain PDC (maybe a standalone server or workstation)
- * is it correct to contact the the pdc of the domain of the user who's password should be set?
- * 2. do a samr_Connect to get a policy handle
- * 3. do a samr_LookupDomain to get the domain sid
- * 4. do a samr_OpenDomain to get a domain handle
- * 5. do a samr_CreateAccount to try and get a new account
- *
- * If that fails, do:
- * 5.1. do a samr_LookupNames to get the users rid
- * 5.2. do a samr_OpenUser to get a user handle
- *
- * 6. call libnet_SetPassword_samr_handle to set the password
- *
- * 7. do a samrSetUserInfo to set the account flags
+ * complete a domain join, when joining to a AD domain:
+ * 1.) connect and bind to the DRSUAPI pipe
+ * 2.) do a DsCrackNames() to find the machine account dn
+ * 3.) connect to LDAP
+ * 4.) do an ldap search to find the "msDS-KeyVersionNumber" of the machine account
+ * 5.) set the servicePrincipalName's of the machine account via LDAP, (maybe we should use DsWriteAccountSpn()...)
+ * 6.) do a DsCrackNames() to find the domain dn
+ * 7.) find out Site specific stuff, look at libnet_JoinSite() for details
