Hello, everyone. I apologize if this question is already asked before, and I'm sure that it did and I also found them in in the Archive, but none of them can resolve my issue that I'm having. Anyway, I installed Samba beta1 from RPM for Redhat 8.0 with LDAP newest version 2.1.21. I got my LDAP up and running, also got SAMBA to talk to LDAP just fine. Created root (as Admin) users, and some other several users. I also created the following groups using net groupmap command, and this is the dump. System Operators (S-1-5-32-549) -> domso Replicators (S-1-5-32-552) -> domrep Guests (S-1-5-32-546) -> domg Power Users (S-1-5-32-547) -> dompu Domain Users (S-1-5-21-783284980-1158383531-2750713796-513) -> domdu Domain Admins (S-1-5-21-783284980-1158383531-2750713796-512) -> domadm Domain Guests (S-1-5-21-783284980-1158383531-2750713796-514) -> domdg Print Operators (S-1-5-32-550) -> dompo Account Operators (S-1-5-32-548) -> domao Backup Operators (S-1-5-32-551) -> dombo Users (S-1-5-32-545) -> domu --------------------------------------------------- Also this is the dump for pdbedit -L -v root: -------------------------------------------------- Entry found for user: root Unix username: root NT username: root Account Flags: [U ] User SID: S-1-5-21-2422541079-1097910024-471466596-1000 Primary Group SID: S-1-5-21-2422541079-1097910024-471466596-1001 Full Name: root Home Directory: \\mymasterserver\root HomeDir Drive: Logon Script: .bat Profile Path: \\mymasterserver\Profiles\root Domain: MYHOMEDOMAIN Account desc: Workstations: Munged dial: Logon time: 0 Logoff time: Mon, 18 Jan 2038 21:14:07 GMT Kickoff time: Mon, 18 Jan 2038 21:14:07 GMT Password last set: Sun, 22 Jun 2003 00:49:45 GMT Password can change: Sun, 22 Jun 2003 00:49:45 GMT Password must change: Sun, 13 Jul 2003 00:49:45 GMT -------------------------------------------------------------- Ok, everything seems just fine, right. Now I went into my XPs and disable the sigorseal and securechannel registry stuff. Then I tried to join the DOMAIN and typed in root as username and password, then I got an error saying "The specified user does not exist". I check the log files and it reported that authentication for root is successful. Now after the error, I checked LDAP tree, and the XP computer name was also added in there just fine. I am clueless/hopeless on what else to do next. I tried everything I could to find any solution but no luck. Please help, if you can provide any HOWTO or up-2-date tutorials on SAMBA+LDAP I would really apreciate it. I tried the other HOWTO but the seem to be out dated now. Thanks for your help. +++++++++++++++++++++++++++++++ And here's my smb.conf: +++++++++++++++++++++++++++++++ [global] # LDAP Stuff here passdb backend = ldapsam #passdb backend = ldapsam smbpasswd guest ldap suffix = dc=mydomain,dc=net ldap machine suffix = ou=Computers,o=smb ldap user suffix = ou=Users,o=smb ldap group suffix = ou=Groups,o=smb ldap admin dn = "cn=Manager,dc=mydomain,dc=net" ldap ssl = no admin users = root @domadm idmap uid = 10000-15000 idmap gid = 10000-15000 log level = 3 # workgroup = NT-Domain-Name or Workgroup-Name workgroup = MYHOMEDOMAIN netbios name = MYMASTERSERVER ..and other basic/default stuff. ------------------------------------------------- Need Web Email Account?
