1)  Get the latest PBIS Open Edition from BeyondTrust (formerly Likewise): http://download1.beyondtrust.com/Technical-Support/Downloads/PowerBroker-Identity-Services-Open-Edition/?Pass=True

2)  chmod 755 the file, execute it, then install it.

chmod 755 pbis-open-7.1.0.1203.linux.x86_64.deb.sh

./pbis-open-7.1.0.1203.linux.x86_64.deb.sh

cd pbis-open-7.1.0.1203.linux.x86_64.deb

./install.sh

3)  Join the domain

sudo domainjoin-cli join guammie.com administrator

4)  Add domain group to sudoers

sudo visudo

%GUAMMIE\\domain^admins ALL=(ALL) ALL

5)  Make domain logins use Bash (or whatever shell you want), refresh lss, and clear ad cache

sudo /opt/likewise/bin/lwregshell set_value ‘[HKEY_THIS_MACHINE\Services\lsass\Parameters\Providers\ActiveDirectory]’ LoginShellTemplate /bin/bash
sudo /opt/likewise/bin/lwregshell set_value ‘[HKEY_THIS_MACHINE\Services\lsass\Parameters\Providers\Local]’ LoginShellTemplate /bin/bash
sudo /opt/likewise/bin/lwsm refresh lsass
sudo /opt/likewise/bin/lw-ad-cache –delete-all

That’s it.
