our client has been using your plugin for a longer period of time now and claims, that it doesn't work anymore. Even though your documentation doesn't suggest it, he claims that logging in worked automatically (without entering ?<KEY> to an URL). As key they use:
Confidential information:
(hidden)
for every user. Was this a feature maybe in a previous plugin verion of yours? Or can this be achieved otherwise?
It works for our developer test account "iplogintestuser" but not for their clients (user group subscriptions), like for example user with ID 880. Here are credentials for you in order to check the configuration. Please consider, that this is a live system, so please don't change any settings for us. Thank you!
