Created attachment 7768 [details] 0001-s4-samr-Rework-GetGroupsForUser-to-use-memberOf.patch Ticket#: 2015110921000315 The attached patch aims to improve the performance of the Samba SAMR GetGroupsForUser call. In the case of the ticket, the Samba rpc_server consumed 100% of a CPU core for most of the time while a couple of smbd connections where running. Finally it turned out that a bunch of Solaris clients without winbind apparently constantly hit the two Samba/AD DCs. The patch makes Samba use the memberOf attribute which sound like the right thing to do.
