I just installed 3.5.2 and encountered the following. Compile worked all right but "getent group" would not give back any results, though "getent passwd" did list those AD users. The server runs as AD member and winbind seems to work normally. "wbinfo -u" and "wbinfo -g" return the desired info just "getent group" sucks. It works using the previous 3.3.8 version as well as with 3.4.7 using an unchanged smb.conf.

Same here with 3.5.4. Also %G is resolved to numeric IDs. getent group GROUP works.
In my case it works if charget is UTF-8. If it's something else then 3.5.4 wbinfo -g doesn't work. getent groups doesn't work 3.5.5 wbinfo -g works. getent groups still doesn't work 3.4.9 works fine.
haven't seen any setup since years where problems like this have been caused by samba itself. mostly it was a configiration problem, nscd not restarted or something like that. closing this old bug now. if u see issues with 4.1, feel free to reopen the bug with verbose description and config files.
