Some common commands for use with Centrify are:
adinfo
adjoin company.com -u aduser@company.com -c company.com/LinuxUsers -z Linux-Clients -V -f >> /var/log/ad/adjoin.log 2>&1
adleave -u aduser@company.com
-> Install only centrifydc paket, not the whole suite. The whole suite destroys things like networking and SSH settings.
