I setup a xwiki for our company and configured the login to auth over ldap or local.
We have dots in our usernames and XWiki does not support dots in usernames jet (Loading...).
We are willing to sponsor that feature, but the sponsor link is broken.
You can’t create XWiki users with a dot in the name with the standard UI. But the users automatically created by LDAP when they connect can contain a dot in the uid (the LDAP authenticator simply don’t store them with the dot but remember the uid in a object of the user profile).
