Introduction to Templates ! Template Groups ! Control Metadirectory Templates ! Control Connected Directory Templates ! The Template Language ! Modifying Existing Templates ! Creating Templates ! Best Practices Management agents use templates to import directory update files from their connected directories and export update files back to them. Modifying or creating templates involves working with languages and functions. The template language is used to create templates that are interpreted by management agents when importing or exporting directory data. The template language’s basic purpose is to assign values to attributes. An understanding about how to create and use templates is essential to manage the flow of identity information between the metadirectory and the connected directories in Microsoft ® Metadirectory Services version 2.2 (MMS). At the end of this module, you will be able to: ! Describe the purpose and function of templates. ! Identify the different types of template groups used in the functioning of management agents. ! Describe the purpose of the different types of Control Metadirectory templates. ! Describe purpose of the different types of Control Connected Directory templates. ! Describe the template language used to modify and create templates. ! Modify existing templates by editing the Parsing template and the Metaverse Construction template. ! Create Parsing and Construction templates. ! Describe best practices for creating and modifying templates. Topic Objective To provide an overview of the module topics and objectives. Lead-in In this module, you will learn about restructuring data between a connected directory and the metadirectory by modifying the Parsing and Construction templates. 2 Module 5: Modifying and Creating Templates BETA MATERIALS FOR MICROSOFT CERTIFIED TRAINER PREPARATION PURPOSES ONLY Introduction to Templates Create File(s) Create File(s) Connected Directory Connected Connected Directory Directory Metadirectory Update Update Metaverse Namespace Metaverse Namespace MA’s Connector Namespace MA’s Connector Namespace Templates Templates Templates Templates Templates Templates Import File(s) Import File(s) Discovery Discovery Discovery Synchronization Synchronization Synchronization A management agent reads import file(s) and updates metadirectory entries. But how does the management agent know the format and contents of the file, and how does it know what to do with those contents? The management agent templates provide this information. Though the management agents import directory update files from their connected directories and send update files back to them. However, the management agent templates are the programs that read or write those files. Templates are written in a high-level, interpreted language that the management agent, in particular the Importt program, interprets and acts upon when importing or exporting directory data. Templates ultimately define the import and create files in terms of directory attributes. Templates not only specify how the data in the input file(s) is to be placed in the metadirectory; but they also specify what attribute information from the metadirectory is to be placed in the create files to update connected directory attributes. Templates are the mechanism that MMS uses to map the attributes from different connected directories to the attributes of the metadirectory. In other words, map the schema of the connected directory to the MMS schema. Topic Objective To identify the purpose templates. Lead-in Delivery Tip Use the graphic on the slide to show that it actually the templates and not the management agent that import directory update files from connected directories and send update files back to them.

When constructing a metadirectory entry, it may not be necessary to export all the attribute information; therefore, you may need additional information. The additional information may include values for all the attributes that make up the entry’s distinguished name, as well as the entry’s object class. These attributes must be constructed from information in the input record of the import file and other information that is known to the management agent. Each management agent has different types of templates to move information in and out of metadirectory. Control Metadirectory Templates These templates control the metadirectory data flow into the connector namespace and the metaverse namespace. A program called Importt uses these templates to process one or more import files discovered from a connected directory resulting first in modifications to the connector namespace and then in modifications to the metaverse namespace. Control Connected Directory Templates These templates control connected directory data by affecting the connector namespace entries associated with a connected directory. Importt uses these templates to process metaverse namespace data resulting first in modification to the connector namespace data and then create files, which represent the modifications to the connected directory. Topic Objective To identify the different types of template groups used in the functioning of management agents. Lead-in 4 Module 5: Modifying and Creating Templates BETA MATERIALS FOR MICROSOFT CERTIFIED TRAINER PREPARATION PURPOSES ONLY Control Management Agent Operations The script and template definitions control operations to and from a connected directory, and the import and create files. The script, called the management agent Control script is processed by a script engine called Zscript. The management agent Control script is responsible for getting data from the connected directory and creating one or more import files. The management agent Control script also uses the create file to transfer modifications to the connected directory. This Control script calls a program called Cdir_xx to perform the actual communication to the connected directory. The Cdir_xx Program The management agent Control script invokes the Cdir_xx program during the discovery and update phases. The Cdir_xx process, when running in the discovery phase, produces a text file. The text file contains information, such as name, address and mailbox from the connected directory. The _xx represents an abbreviation for the type of management agent. For example, Cdir_ln represents Lotus Notes. The Importt Program The management agent control script invokes the Importt program during the synchronization phase. The Importt program reviews the text file data produced by Cdir_xx, interprets templates, evaluates attribute flow rules, and then updates the metadirectory. The Importt program also flow attributes from the metadirectory back to the connected directory, through create files, which Cdir_xx will send back to the connected directory.

Each management agent has a set of templates that operate as mediators between the metadirectory and the connected directory. The following are the two types of Control Metadirectory templates. ! Parsing templates. Parsing templates enable the Importt program to understand the data format in the import file, how to handle the data, and identify the attributes. ! Construction templates. The Construction templates act as a blueprint for the management agent on how to use the attributes from the connected directory to construct entries in the connector namespace and the metaverse namespace. Each management agent has a set of Construction templates to supplement the Parsing templates. Topic Objective To identify the Control Metadirectory templates.

Different types of Parsing templates help the management agent interpret different types of records in import files. The following list describes the different types of Parsing template: ! Add. The Add template describes a record representing a complete connected directory entry. ! Modify. The Modify template is similar to the Add template for those connected directories that output a modify record format. When processing a Modify template, the management agent does not presume that the record contains a complete set of attributes. ! Delete. The Delete template describes a deletion record in the import file. A deletion record is only processed if the management agent is in reflector mode. If the Delete template is applied to an entry in a connector namespace, the ConnectedDirectoryId (which is an attribute on the connector) value is removed from the joined metaverse namespace entry, and results in a disconnector. If there are no other connectors pointing to the metaverse namespace entry, the metaverse namespace entry is deleted. ! Header/Trailer. The Header and Trailer templates describe the header and trailer records. The Header and Trailer templates also allow the management agent to ignore information that is not relevant to the update phase. Template types are matched to record types by the starting text string or label in the record. If a management agent cannot positively identify a record type, the management agent rejects it, displaying an error in the operator's log.
