Managing Users
Users can be managed from the Participant Administration table. See Finding Participants for information about locating existing users and adding them to the table. Clicking the new user icon allows you to create a new user.
There are some restrictions for the user name you enter for a new user:
User names cannot include the following characters: #, /, >, \, and <.
Because of known problems with the Apache and Sun ONE web servers, user logon names cannot contain multi-byte characters nor extended ASCII characters such as ä, ê, ì, õ, ǚ, æ, and so on.

Although the Participant Administration utility does not require that users have an email address, the following features in Windchill require that users have an email address:
Giving the site administrator privileges through the Site > Administrators window
Giving the organization administrator privileges through the Organizations > Administrators window
Enabling the user to create products, libraries, or projects through the Organizations > Creator window
Adding the user as a member of a project through the Team window in the Project context
After a user is added to the table, you can manage the user.
Managing users includes performing the following activities:
Creating users
Searching for users
Editing and deleting users
When deleting users, you can delete them from just the Windchill database or delete them from both the database and the user directory service.
Creating users from existing users
Associating users with profiles
Editing the domain and personal cabinet of a user
Viewing information about users
Defining electronic signatures for users
Assigning pictures for users
Managing personal cabinet names
From Windchill PDMLink and Windchill ProjectLink, you can administer personal cabinets from Site > Utilities > Personal Cabinets Administration.
Purging users from the cache
Synchronizing the teams’ membership with updated user-defined groups
For more information, see Synchronizing Team Membership for Users and User-defined Groups.
For more information on performing these activities, see the help available from within the Participant Administration utility.
