This includes details on how to configure and run the Standalone LDAP Daemon, slapd8. It is intended for new and experienced administrators alike. This section provides a basic introduction to directory services and, in particular, the directory services provided by slapd8. This introduction is only intended to provide enough information so one might get started learning about LDAP, X. A directory is a specialized database specifically designed for searching and browsing, in additional to supporting basic lookup and update functions. Note A directory is defined by some as merely a database optimized for read access. This definition, at best, is overly simplistic. Directories tend to contain descriptive, attribute based information and support sophisticated filtering capabilities. Directories generally do not support complicated transaction or roll back schemes found in database management systems designed for handling high volume complex updates. Directory updates are typically simple all or nothing changes, if they are allowed at all. Directories are generally tuned to give quick response to high volume lookup or search operations. They may have the ability to replicate information widely in order to increase availability and reliability, while reducing response time. When directory information is replicated, temporary inconsistencies between the replicas may be okay, as long as inconsistencies are resolved in a timely manner. There are many different ways to provide a directory service. Different methods allow different kinds of information to be stored in the directory, place different requirements on how that information can be referenced, queried and updated, how it is protected from unauthorized access, etc. Some directory services are local, providing service to a restricted context e. Other services are global, providing service to a much broader context e. Internet. Global services are usually distributed, meaning that the data they contain is spread across many machines, all of which cooperate to provide the directory service. Typically a global service defines a uniform namespace which gives the same view of the data no matter where you are in relation to the data itself. A web directory, such as provided by the Open Directory Project lt http dmoz. These services catalog web pages and are specifically designed to support browsing and searching. While some consider the Internet Domain Name System DNS is an example of a globally distributed directory service, DNS is not browseable nor searchable. It is more properly described as a globally distributed lookup service. LDAP stands for Lightweight Directory Access Protocol. As the name suggests, it is a lightweight protocol for accessing directory services, specifically X. LDAP runs over TCPIP or other connection oriented transfer services. LDAP is an IETF Standard Track protocol and is specified in Lightweight Directory Access Protocol LDAP Technical Specification Road Map RFC4. This section gives an overview of LDAP from a users perspective. What kind of information can be stored in the directoryThe LDAP information model is based on entries. An entry is a collection of attributes that has a globally unique Distinguished Name DN. The DN is used to refer to the entry unambiguously. Each of the entrys attributes has a type and one or more values. The types are typically mnemonic strings, like cn for common name, or mail for email address. The syntax of values depend on the attribute type. For example, a cn attribute might contain the value Babs Jensen. A mail attribute might contain the value babsexample. A jpeg. Photo attribute would contain a photograph in the JPEG binary format. How is the information arranged In LDAP, directory entries are arranged in a hierarchical tree like structure. Traditionally, this structure reflected the geographic andor organizational boundaries. Entries representing countries appear at the top of the tree. Below them are entries representing states and national organizations. Below them might be entries representing organizational units, people, printers, documents, or just about anything else you can think of. Figure 1. 1 shows an example LDAP directory tree using traditional naming. Figure 1. 1 LDAP directory tree traditional namingThe tree may also be arranged based upon Internet domain names. This naming approach is becoming increasing popular as it allows for directory services to be located using the DNS. Figure 1. 2 shows an example LDAP directory tree using domain based naming. Figure 1. 2 LDAP directory tree Internet namingIn addition, LDAP allows you to control which attributes are required and allowed in an entry through the use of a special attribute called object. Class. The values of the object. Class attribute determine the schema rules the entry must obey. How is the information referencedLinux Tutorial Apache Web Login Authentication. Apache authentication and autorization Intro. Apache authentication can be configured to require web site visitors to login with a user id. This is different than adding a login form on a web page. This tutorial describes the various. Apache and its configuration. Login protection is applied to the web pages stored in a directory. The login dialog box which requests the user id and password is provided by. Apache. Apache allows the configuration to be entered in its configuration files. Five forms of authentication are detailed here Apache password file. LDAP, NIS and My. SQL. Apache authentication methods using local files to store passwords, have no. If using LDAP or NIS for system login. Apache web site logins. Authentication Prove it is you. Authenticate the login by requiring a password only the user would know. Authorization Only certain users or members of a privaleged group are allowed. Typically Authentication or Authentication and Authorization are required for access.
