It is CentOS-based but comes up with a slick web based administration program and uses LDAP for authentication out of the box. It uses openldap and I think it is integrated with samba so you could use windows clients if you wanted. On something of that scale I don't think you'd have to worry about the performance or replication differences in openldap or directory server - the administrative tools you use will be more important. -- Les Mikesell lesmikes...@gmail.com ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

There is a quite good article about setting up LDAP (OpenLDAP) and migrating from file-based authentication on the RedHat RHEL documentation site (this applys equally well to CentOS). > > My question is more general, and I don't want to go into technical > details.

Samba would be combersome in a pure-Linux environment. NFS would propagate standard UNIX permissions transparently. You could also use automount to reduce 'clutter' (only mount what is needfull on an as-needed basis).

While this article mostly covers a server serving a bunch of *diskless* workstations, many of the basic ideas also apply to a situation with workstations with local disks. > > Any suggestions? > > Cheers from the hot South of France, > > Niki > ___ > CentOS mailing list > CentOS@centos.org > http://lists.centos.org/mailman/listinfo/centos > > -- Robert Heller -- 978-544-6933 Deepwoods Software-- Download the Model Railroad System http://www.deepsoft.com/ -- Binaries for Linux and MS-Windows hel...@deepsoft.com -- http://www.deepsoft.com/ModelRailroadSystem/ ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Standard posix perms can take care of that, for finer grained perms you can use ACLs. > So far, I've only dealt with local authentication.

NIS is easier then LDAP and might be a good quick-n-dirty way to get going initially. Just use a separate authentication service like Kerberos and keep passwords out of the directory service. > My question is more general, and I don't want to go into technical > details.

And what's this thing called Directory Server, which > vaguely sounds like it's the right way to go? You can really mash all these technologies up. If all clients are Linux then start with NFS/NIS/Kerberos then as things grow you can look to move to LDAP. The "Directory Server" is a turn-key package for implementing LDAP plus Kerberos with a pre-established LDAP schema and tools to manage it. Definitely worth taking a look at. Personally I don't have experience with it so can't recommend or not recommend it. You COULD also have a Windows Active Directory server to provide LDAP and Kerberos services to your Linux environment. They definitely have nice management tools. MS for not-for-profit is dirt cheap. Run it as a VMware/VirtualBox/KVM/Xen VM. Hell, run the whole server as an ESXi host and have multiple VMs for redundancy/load spreading. -Ross ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

We have a similar setup with OpenLDAP and NFS. Works OK, except all directories defined are home to the users, and only their owner can read them. Adding users or changing passwords is an admin-only hassle, because we have never found a user management tool for LDAP which was convincingly able to be given away to teachers. -- Eduardo Grosclaude Universidad Nacional del Comahue Neuquen, Argentina ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] Simple solution for small network in a school ?
Hi, I have to install a small network in a school in a nearby village. The network will be Linux-only, one server and fifteen desktops. Here's the idea. 1) Authentication should be managed centrally on the server. 2) User home directories should also be on the server. 3) Users should all have disk quotas, something like 1 GB per user. 4) Some shared directories should be read/write for a defined group of users (teachers) and read-only for others. So far, I've only dealt with local authentication. I have a little practice in basic setups of Samba and NFS and managed to get these to work OK. On the other hand, I've never worked with NIS, LDAP or the likes. My question is more general, and I don't want to go into technical details. According to the KISS principle, which solution would you recommend (or explicitly *not* recommend)? A mix of LDAP and Samba? Or NIS and NFS? And what's this thing called Directory Server, which vaguely sounds like it's the right way to go? Any suggestions?
