[Bug 1572876] Re: After Samba upgrade can't access unpassworded windows share

[Victor Hugo dos Santos]

Hi,

we have problems with this new version too... the system stop to work (with out memory) after a time and I cant get the user list from the domain, like in this bug report:
http://www.spinics.net/lists/samba/msg133470.html

Note1: wbinfo -u not work but wbinfo -g work perfectly.
Note2: on my case, rejoin to domain not work, only making a downgrade to the previous version (2:4.1.6+dfsg-1ubuntu2) work again.


on log-wb.DOMAIN I see:
