Works perfect with my last instalation in google.. and roundcube.. Must use you full user mail login @google.com included... Only need better docs for the instalation.. (if you upgrade the you rouncube install please reinsert your login user and pass) running on roundcube 1.01
Not working anymore for the appropriate google login needs. I had to change my google password, because there is no link in the plugin (user and password section of the plugin) to make googe grant access to the plugin. This can only be done in the google account (google website). Not really an option for the average user, because this is too complicated and too dangerous. Photos in the google addresses are not supported and making the whole google address book not working. Google contacts without photos are working though. As I can see, since 11.11.2011 this plugin is not anymore updated, all bugs in the tracker remained open, which is not a good sign for using it. Better don't try it and import your google contacts manually, avoiding probably sync-problems when using a buggy plugin.
