I am also using ISPConfig (184.108.40.206 Version) and I want to connect it with GO (3.7.45 Community Version). I've downloaded the modules and placed them into groupoffice module folder, but I am not sure what you mean with the first 2 steps
1) Add a new remote user at ISPconfig3 with the following functions mail,client,server ?? I am able to create users in ISPC, but how do I assign functions to it? Or did you mean GO instead?
2) Add the ispconfig3_... parameters to the groupoffice config file /etc/groupoffice/config.php ?? I understand the config.php needs some parameters for the modules, can you show me which parameters exactly?
Any help would be greatly appreciated, because I love both products!
