NEG_CONN_CACHE questions
I've tried searching manuals and wiki, but I can't seem to find any specifics about NEG_CONN_CACHE entries other than 'idmap negative cache time' option in smb.conf, which refers to SID/UID/GID queries and not unavailable DCs. Specifically the issue I've ran into recently is that with 'winbind max domain connections' set to 10 I saw Winbind had single active connection to the...

samba 4.7.7 shares on FreeBSD 11.1-p11 started to ignore ACL
Hi, This morning three of our FreeBSD-11.1-p11 servers with Samba 4.7.7 installations started to ignore ACL settings and reject user access to shares.  All three servers are members of DC running on Windows Server 2008R2.  Everything has been running ok for last few year.  I have been upgrading Samba and FreeBSD installations and on last Friday upgraded to the latest packages from

On my home network (IPv4 and IPv6), a box with Samba 4.2.10 with IPv6 disabled (via sysctl), will fail to contact a DC because the IPv6 connect fails immediately before the v4
