fixed merge problems
changed exec mode on bin and sbin
added sha256sum entries for 6.3 and 7.1
removed printing stuff; removed explicit password server
verifying that host can reach domain controller

cleaning up /opt/taos/samba3 if samba3 is installed ; failing with error if /opt has insufficient capacity for installation
preferring 5 closest DCs as password servers; fixing some grep problems; creating /opt before testing capacity thereof; better reachability tests; only modifying nsswitch and pam config files if domain join succeeded
merged in from 7.1-RELEASE-JNPR: preferring 5 closest PDCs, specifying netbios hostname, detecting DC reachability failure, different sha256 sums for 6.3 and 7.1, only modifying nsswitch.conf and pam.d/sshd after net join succeeds, removed cups configuration from smb.conf
