Same here. It worked fine with 10.7.2 and now its broke. I will try to follow again --> http://support.apple.com/kb/HT4704 as soon as I have a minute and see whether it works again.
Lion brought me nothing but trouble, problems and restrictions yet. I am close to downgrade again and skip all about iCloud.
For anybody who might take advantage ... I actioned KB HT4704 again. In spite of error message of the dseditgroup commands it worked afterwards and survived even a reboot. I am curios whether the subsequent fix packs will brake ftp again. So, I am still not sure whether I will keep Lion. Just to much trouble and missing functionality
