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!
