Establishing Administrators
Before you attempt to use your Windchill solution, you should establish a minimum set of administrators for the solution. The types of administrators that are available are determined by the Windchill solutions that are installed.
The Administrators group is defined in every installed Windchill solution. Initially, the administrative user entered during installation (for example, wcadmin) is the only member. Out of the box, the members of the Administrators group have full control over all Windchill objects and are commonly called the system or site administrators.

If you want to use a site administrator to manage contexts or teams, you should create a second site administrator for these tasks to improve Windchill performance. For more information, see Establishing Site Administrators.
The additional types of administrators available are:
An organization administrator manages a specific organization.
A product manager manages a specific product (for Windchill PDMLink, Arbortext Content Manager).
A library manager manages a specific library (for Windchill PDMLink, Arbortext Content Manager).
A project manager manages a specific project (for Windchill ProjectLink).
A program manager manages a specific program (for Windchill ProjectLink).
A shared team manager manages a specific shared team and has management privileges for any context using the shared team.
In the out-of-the-box configuration, there are two LDAP directory service nodes. Administrative users reside in the Administrative LDAP node. For more information about the LDAP services, see Working with LDAP Directory Services.
* 
For notification email messages to be sent, some mail servers require that a valid email address be specified in the From header of the email message. Windchill solutions use the wt.mail.from and wt.notify.notificationSenderEmail properties in the wt.properties file to populate the From header when sending email messages. Setting these properties to a valid Windchill user should have been done as a manual step after installing your solution. If this was not done, see Setting Sender E-mail Address for details on how to set these properties to the email address of the Windchill administrator or some other authorized user.
The site administrative user (as defined by the Administrators group) can use the links that are under Site and Organizations .
Selecting Site > Administrators displays the Site Administrators table. From this table, you can add users to the Administrators group.
Additionally, you can give system monitoring privileges to a group of Windchill users who are not in the Administrators group. By listing the user names of those users in the wt.util.jmx.AccessUtil.siteAdministrators property, the users have access to the System Configuration Collector, Server Status, and Monitoring Tools pages. These users should also be included in the JMX-Administrators list so that they automatically receive the JMX email notifications and the end user error report emails that are sent. For JMX-Administrators list and wt.util.jmx.AccessUtil.siteAdministrators property details, see Setting Up Your JMX Environment.
The following sections provide additional information about the administrators in each Windchill solution and describe how to add the administrators.
