As we close another chapter, we can take stock of all that we have acquainted ourselves with in the process. The big task for this section was to become more accustomed to the vagaries of CentOS group management and being able to properly differentiate between the primary group and secondary groups of a user. During this process, we took the time to evaluate the use of public and private group schemes and the use of the -N option to disable the user's private group during user creation.

It was not long before we found ourselves in the depths of /etc/nsswitch.conf and the getent command (get entries). From here, we got down straight to business implementing user disk limits or quotas before seeing how to link all of this together with scripts.

In the next chapter, we stick to the theme of users, but look at centralizing our accounts in a central LDAP directory, using the open source code from Red Hat's directory server by implementing the 389 Directory Server on CentOS 6.5.
