Hello, I traditionally use the 'ad' backend on member machines with rfc2307. I decided to give 'rid' a go on a server only performing authentication. Everything went well with join but I have a few questions. First my smb.conf on Ubuntu 16.04.4 LTS [global] security = ADS workgroup = DOMAIN realm = DOMAIN.LOCAL log file = /var/log/samba/%m.log log level = 1 idmap config * : backend = tdb idmap config * : range = 3000-7999 idmap config DOMAIN : backend = rid idmap config DOMAIN : range 10000-999999 winbind nss info = template template shell = /bin/bash template homedir = /home/%U Output of 'getent group' getent group "DOMAIN\\Domain Users" DOMAIN\domain users:x:10513: Output of 'getent passwd' getent passwd DOMAIN\\James DOMAIN\James:*:14659:10513:James Test:/home/james:/bin/bash My other member servers that utilize the 'ad' backend utilize the same DOMAIN range of 10000-999999 and I assign uid's and gid's via. RSAT. * Is it OK to run multiple member servers with different domain backends in a forest? * Is it OK to use the same range with different domain backends? Thanks. -- -- James
