Hi Ron, Curtiss, Scribu and (if you're listening - I added a tag) Otto,
I just ran in to a little snag with a site on a network installation where I have Simple Google Connect running to allow users to identify with SSO. But now the site needs to go behind a login and I tried Network Privacy which works great except when trying to connect through SSO.
Whet happens is this: the login screen comes up and after hitting the SSO button the popup window with Google login form comes up (all normal here still) but after login, the popup window does not disappear like normal (redirecting to the dashboard) but instead shows the WordPress login form where my username is filled in. Nothing to indicate that there was a successful connection, nor any error messages.
The funny thing is that the connection was in fact successful because when I close the popup (ignoring the login form in that window) and hit the "Return to site" link below the original login form, the site is suddenly accessible and I'm connected :)
So it seems to be just a redirection problem.
I have activated Network Privacy on the network with the default empty setting (meaning 'all open', I presume?) and then set this particular site to allow only Subscribers (and up, I presume?).
Note: I also tried the plugins More Privacy Options and Multisite Privacy (from WPMUDEV) but these two actually do NOT work at all in combination with SSO by Simple Google Connect.
