Proposal In this presentation, solutions to some common systems management problems will be discussed and solved utilizing Red Hat Directory Server/389. You have dozens, hundreds or thousands of systems to manage. You can't treat each one individually, even though each system has unique characteristics, and purposes. You may have processes that don't scale well due to specifications and requirements for approval or acceptance on a per host, per user account or or per group basis. Let your LDAP directory help you solve these problems, without many schema modifications, or layered products. This topic will demonstrate real-world examples of storing system metadata, user information, DNS and even application configuration information, in an LDAP container designed to scale and replicate easily. Utilizing simple concepts such as set theory, in conjunction with configuration management tools such as puppet you can build out technology that enables excellent process flow and auditing. This allows you to concentrate on building re-usable infrastructure services that are highly available. Granular topics and points will include examples of application configuration for source code management solutions, monitoring, email, DNS and others. It will also include code snippets to demonstrate the security settings and restriction of the LDAP server.
