realm = DOMAINB

template homedir = /home/%U
template shell = /bin/bash
winbind expand groups = 1
winbind separator = +
winbind use default domain = Yes
idmap config domainb : range = 3000001 - 4000000
idmap config domainb : backend = rid
idmap config domainc : range = 2000001 - 3000000

idmap config domaina : range = 1000001 - 2000000

idmap config * : range = 1000000-199999999
idmap config * : backend = tdb
BUILTIN : online
SERVER01 : online
DOMAINB : online
DOMAINA : offline
As you can see DOMAINA is offline, if we open up the firewall it is online and are able to logon with a user from DOMAINA on SERVER01.
