[Network Administration]: Kerberized SSH

At this point, most of the infrastructure is in place. Now I could tie some other services together with this infrastructure. For my servers (not the kerberos KDC and LDAP directory), I’ve configured kerberized SSH. It’s a good starting point to see the benefits of single sign-on.

[Network Administration]: Automounter over LDAP

This is basically an update to the autofs and automounter page that was published earlier to reflect some changes to how things are set up now. I still have my automount maps in the LDAP directory, but the DN for the maps is updated to the currently provided autofs schema that comes with the Ubuntu package instead of the rfc2307bis schema which seems to have languished in draft form. I’ve also unified some of the files across both Linux machines and OS X. Continue reading “[Network Administration]: Automounter over LDAP”

[Network Authentication]: OS X Kerberos Authentication and LDAP Authorization

I’ve also enabled Kerberos authentication and LDAP authorization on my OSX machine in addition to Linux machines. OSX supports Kerberos out of the box and deploys it for authentication against an OSX server. Also, the native OpenDirectory implementation is OpenLDAP, so we should be able to talk with our LDAP directory. Additionally, we’ve generated the directory entries with the records that we’ll need for OSX authorization, we just need to enable it.

[Network Administration]: Linux Kerberos Authentication and LDAP Authorization

Once principals are added to the Keberos Database, and the account information is added to the LDAP directory, then the client Linux machines can be configured to access the information and allow for network accounts to be used.

[Network Administration]: Network Accounts

At a basic level, the Kerberos KDC manages the passwords, and the LDAP directory is used to manage user accounts and user groups for both Linux systems and OSX systems. In order to do this, the Kerberos KDC needs to have users and passwords, and the directory needs entries with some basic information that both systems require for authorization. Once the information is in both the KDC and the directory, then both linux and OSX systems can be configured to use the information.

[Network Administration]: LDAP Directory Service – Frontend and Scripts

I’ve got my authentication service and directory set up and running. Now it needs to be populated. In addition to keeping user and group records, I’m going to be using this for a couple of different services in addition to keeping user and group records such as automount maps and information for a mail server (currently in a MySQL database) as well as more traditional directory information. I’ve created the directory to be more deep than wide putting daemon information under it’s own organizational unit. There are also some packages to manage the entries in Perl.
