[Fwd: Re: [Samba] posixAccount for Machines in LDAP?]
---------------------------- Original Message ---------------------------- Subject: Re: [Samba] posixAccount for Machines in LDAP? From: kent@www.warehamportal.mec.edu Date: Wed, July 14, 2004 12:19 pm To: "Paul Gienger" <pgienger@ae-solutions.com> -------------------------------------------------------------------------- Hi Paul, Finally got it to work. This is great!! I had 2 problems. First the script paths were wrong, second neither the smbldap_conf.pm nor smbldap-useradd.pl would pass perl -c syntax check. I should have checked that first. I was tinkering with the perl scripts because I don't use profiles and wanted to delete these from being created. One more thing to do is to get the smb.conf and perl scripts straightened out on the BDCs so everything is the same. Thank you for your support!

Is it making the posix account but not modifying it with sambaSAM information? You are sure that everything is using ou=People (or whatever users container you're using)? I use the root account. When I started this quest I tried to get a root equivalent account to work and couldn't. I may revisit this now that I've overcome other obstacles. I tried keeping the users separate from the computers in smb.conf. This seems to work. It may have been a bug but seems to work for me. ?? Machines go under ou=Computers,dc=tow.net and users under ou=users,dc=tow,net.> >>Just curious, do you have a working system that does just that, where ifyou add a machine by joining it to the domain, smbldap_useradd.pl creates the posixAccount and sambaSAMAccount in LDAP?>> >> > I *did* when I was migration testing for samba3 but now my test box hasbeen scrapped for a Sun trade in. I need to rebuild it before I go live with S3 (still on 2.2.8 here sadly) so I'll be building entirely from scratch again, hopefully this week if other projects get taken care of. I've done a pile of testing in my setup to get it to work with our remote LDAP master and local and/or distributed DC boxes. There were some timing issues there if replication didn't happen quick enough, a real PITA.> >>I'll continue to tinker with it. If you have any other suggestions, let >> me >>know.
