Janne Jalkanen commented on JSPWIKI-507:
----------------------------------------
I'm not sure whether this is really a problem - you can always even delete all
the user accounts and end up with invalid groups.
What is the problem if there are groups which contain only invalid/zero
members? They're not taking resources... The admin can always delete them -
perhaps it would be useful to have a tool which detected them...
(I fear that trying to second-guess all possible combinations for users and
groups is simply too difficult - especially if user management is externalized
to LDAP or something similar. There's no way to know when an user is removed,
for example.)

> Key: JSPWIKI-507
> URL: https://issues.apache.org/jira/browse/JSPWIKI-507
> Project: JSPWiki
> Issue Type: Bug
> Affects Versions: 2.8.1
> Reporter: Bruno Peeters
>
> It is possible to define members for a group who are not defined in the wiki.
> There is no check whether the entered names are valid wiki names or full
> names.
> It is possible to edit the membership of a group ("edit group"). If the last
> user of a group is removed - the box showing the group members is empty - and
> the save button is clicked, there is no warning that it is not possible to
> remove the last user of a group. Although the user may think that he removed
> the last user, the requested removal has not been carried out.
> If a group is created by a valid user, and a non existing user is added, and
> finally the creator of the group removes himself of the list of group
> members, the group remains with only one member, not defined within the wiki.
> By default only members of the group can edit the membership list. There is
> currently no check that the last remaining user of a group is indeed a valid
> wiki user.
