I was pointed to: http://web.vcs.u52.k12.me.us/linux/smbldap/ As an effective script to get samba/ldap configured for a PDC. It is written for Fedora 3 core or the K12LTSP distro. of course I discovered this after installing the Centos distro. Now it is decision time: stay with Centos and get this working or move the the K12 distro. This setup is for the small business network in my basement (really quite extensive, a rack full of servers and workstations!). When I run the script I get these messages, errors (I cut out the rpms it found or comes with): Gathering system information... Checking for perl-IO-Socket-SSL-0.92-8.k12ltsp.0.3.1.i386.rpm...not found. Checking for perl-Crypt-SmbHash-0.02-1.1.fc2.dag.noarch.rpm...not found.

I need to install perl-IO-Socket-SSL-0.92-8.k12ltsp.0.3.1.i386.rpm (located on cd #3 of the distro media) I need to install perl-Crypt-SmbHash-0.02-1.1.fc2.dag.noarch.rpm (included with this script) I need to install perl-Digest-SHA1-2.07-5.i386.rpm (located on cd #1 of the distro media) I need to install perl-XML-SAX-0.12-7.noarch.rpm (located on cd #2 of the distro media) I need to install perl-LDAP-0.31-5.noarch.rpm (located on cd #2 of the distro media) I need to install perl-XML-NamespaceSupport-1.08-6.noarch.rpm (located on cd #2 of the distro media) I need to install perl-Net_SSLeay-1.23-8.k12ltsp.0.3.1.i386.rpm (located on cd #3 of the distro media) I need to install perl-Convert-ASN1-0.18-3.noarch.rpm (located on cd #2 of the distro media) Please insert cd #2 from your k12ltsp-4.2 distribution media set. So what do I do? Where can I find all of these? Just run rpm to the Centos servers? Since these are all Perl, just build the right iso images and cheat? Reinstall with K12LSTP? Thank you for your help.
