Pending Users
A user who is known only through email is stored in Windchill as a pending user. Commonly, these users are added to a context team via email and there is no Windchill user with a matching email address. A pending user does not have an associated LDAP entry. Pending users appear in Windchill with a status of Pending and with only the available email address for the user name.
Pending users cannot log on to Windchill until they are activated.
