OK, with help of my boss we were able to get the xmlrpclib patch to work with Authentication. Basically I did as before, with a duplicated, modified version "xmlrpclibx", and used it: import xmlrpclibx t = xmlrpclibx.BasicAuthTransport('myusername','mypassword') # I have to create the new modified transport with this call! s = xmlrpclibx.Server("http://....0",t) # and passed t as argument! print s.imin.short() Then it worked. I just didn't create the right object to pass in, that's all. Happy Holidays again, everyone!
