Hi,
from the hints I managed to cobble together a piece of code that
works. Another problem
was presented by the multithreading that happened when a user opened
several iFrames
containing XWiki pages at the same time. This led to the weird
behaviour of stuff changing
while I was processing the user.
Thanks,
J.L.Simon

LDAP authenticator does not create groups but it assign users to them,

of class XWiki.XWikiGroups each object representing a member (a user
or a sub-group).
Look at XWikiLDAPAuthServiceImpl#addUserToXWikiGroup to see exactly
what means adding a user in a group. If you want to check if a user is
in a group simply look if this group's document contains the member
object for this user object.
Hi,
The best documentation right now is to look at existing
authenticators
like XWikiLDAPAuthServiceImpl which create/update users and add/
remove
users from groups.
Unfortunately, the existing authenticator implementations do not seem
to create groups and
assign users to them. The current code works somewhat, but it has one big problem! The
following methods produce flaky results at best:
XWikiGroupService gService =
context.getWiki().getGroupService(context);
boolean groupHasUser = gService.getAllGroupsNamesForMember(user, 100,
0, context).contains("XWiki."+PORTAL_GROUP_NAME);
boolean userInGroup =
gService
.getAllMatchedMembersNamesForGroup("XWiki."+PORTAL_GROUP_NAME,
null, 1000000, 0, true, context).contains(user);
many times, both calls suggest that the user is not in the group!
Even
if he is! Which means
that the user is added to the group many, many times! The first call
to gService is the most
unreliable, but I would prefer it to the second call, since we're
talking a potential 10.000
users or more. I don't want to lug around collections with 10k+
objects just to check if the
user is in the group?
Help!

Hi,
sorry for being thick, but I can't find any documentation at all
how
to do this in Java and I still
need some help with this.
In our authenticator I'd like to check if users coming from a
certain
angle (i can check on that
through cookies) are in a special group. If they are not, I'd
like to
add the to this group.
Furthermore this group needs to asserted of, so I need to be able
to
reliably find out if it
does exist and if not, create it.
So far I've been frustrated by failure by attempting to use the
XWikiGroupService to achieve this.
Also I don't seem to be able to find a clean documentation on how
users and groups and done
in XWikI (in java, especially). Is there such documentation?
The following code, to much bewilderment, creates a USER?!
public void checkPortalGroup(XWikiContext context) {
if (!_portalGroupChecked) {
try {
boolean groupExists = false;
List<String> groupList =
context.getWiki().getGroupService(context).listAllGroups(context);
for (ListIterator<String> groups = groupList.listIterator();
groups.hasNext() && !groupExists;) {
groupExists = groups.next().equals(PORTAL_GROUP_NAME);
}
if (!groupExists) {
log.info("Group "+PORTAL_GROUP_NAME+" does not exist and
will be created.");
BaseCollection portalGroup =
context.getWiki().getGroupClass(context).newObject(context);
portalGroup.setName(PORTAL_GROUP_NAME);
context.getWiki().getHibernateStore().saveXWikiObject((BaseObject)
portalGroup, context, true);
}
} catch (XWikiException e) {
log.error("Exception while locating or creating group
"+PORTAL_GROUP_NAME+" : "+e.getMessage());
e.printStackTrace();
}
_portalGroupChecked=true;
}
}
I need some serious pointers on how the xwiki objects/classes thing
is
supposed to work
for users/groups.
Thanks a lot,
J.L.Simon
