AW: [opencms-dev] CmsUser as a session variable

Is it possible to create a webuser in the Admin interface?
We are building an Intranet for our one of our clients. The requirement we
have is that OpenCMS administrators will be able to create users within
OpenCMS who will be allowed access to certain priveleged areas of the
Intranet. This is why I am not using the WebUser object.
The code now works for logging users in and reads as follows:
---------------------------------------
CmsJspActionElement cms = new CmsJspActionElement(pageContext, request,
response);
CmsObject cmso = cms.getCmsObject();
String username = request.getParameter("username");
String password = request.getParameter("password");
try {
String webUser = cmso.loginUser(username,password);
out.println("You are now logged in as " + username);
out.println("<br>User is a member of the following groups:<br>");
Vector userGroups = cmso.getDirectGroupsOfUser(username);
CmsGroup thisGroup;
for (Enumeration allGroups = userGroups.elements();
allGroups.hasMoreElements();) {
thisGroup = (CmsGroup)allGroups.nextElement();
out.println("<br>" + thisGroup.getName() + ": " +
thisGroup.getDescription());
}
} catch (Exception ex) {
out.println("Error logging in");
}
---------------------------------------
Does this user get added to the session automatically? If the user logs in
and then clicks on a link to a privileged area, how would I check that they
have a valid session?
Thanks,
Ben

Ben,
Not sure if I understand all of your problem, but in addition to Frank's
message I would add that you should look at the loginWebUser and readWebUser
methods as well. They are scoped to WebUser, and use a different set of
permissions than loginUser.
See the javadoc for more info.
