Hello While using authorize_user, I have to pass the username and password. The documentation says, that both has to be "byte", which I expect to be base64string. While passing the params, I get the response that the first one has to be in base64 and the second one as string. Then I get a correct response back, but with a '0' as result. I am using vBulletin, so I tried to use MD5 Hash as password, with no success. I guess i have to somehow encrypt the password, but how? Thanks Response: "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<methodResponse>\n<params>\n<param>\n<value><struct>\n<member><name>authorize_result</name>\n<value><boolean>0</boolean></value>\n</member>\n</struct></value>\n</param>\n</params>\n</methodResponse>"
