generate the LTPA token; the failing server could not decrypt the LTPA token.
Problems in search of users or groups
The Manage Users and Groups portlet plays important roles in validating and assigning
Portal Access Control permissions. It is the tool for portal administrators to manage the users
and groups, and manipulates the membership structure without directly accessing the
back-end user registry.
After the security is enabled and users are able to log in, they often see problems of locating
users or groups, or cannot verify their relationships. There cases most often encountered are:
Cannot find users or groups, or only some of them can be found, but not others.
Users are found, but cannot be displayed correctly.
Not able to find users in a group when clicking the group.
The group is too large, the sizelimit is exceeded, or a timeout occurs (customize the
portlet).
In Figure 4-9, we show a problem of searching groups.
