Retain GroupWise Plugins

Windows 32-bit Client Plugin

Here is an explanation of how the plugin works:

• When you click the plugin it makes an initial request to the Retain server asking for a key.

• The request is a standard http(s) get: http://retain.acme.com/RetainServer/Server/ServerController2.jsp?method=webacc.getRandomString

• The plugin should receive this key back from the Retain server.

• The plugin takes the key and uses it to create another http get but this time portions of the URL are encrypted.

• The plugin then calls the Windows ShellExecute function which loads the browser and passes it the encrypted URL. If the browser isn't specified via the Windows registry the default browser will be launched (see https://support.microsoft.com/en-us/kb/170918).

• The Retain server receives the http request and tries to decrypt the URL. If it's successful it returns the user's Retain mailbox. If not, you get the standard login screen and the error you're seeing.

• Usually the problem is the plugin doesn't get the key after the first request.
