I know you can do a silent install on the OnGuard client. (see below) I have asked engineering on the combo.
Silent Install
Windows
OnGuard Installers (both EXE and MSI) support silent install.
MSI Installer supports standard msiexec options:
/quiet
Quiet mode, no user interaction
/passive
Unattended mode - progress bar only
/q[n|b|r|f]
Sets user interface level
n - No UI
b - Basic UI
r - Reduced UI
f - Full UI (default)
Example - "ClearPassOnGuardInstaller.msi /qn"
For EXE Installer we need to pass '/S' as argument - "ClearPassOnGuardInstaller.exe /S"
Please note that silent mode should be launched with Admin rights, otherwise installation will fail without showing any error.
Mac OSX
hdiutil attach ClearPassOnGuardInstall.dmg
sudo installer -pkg /Volumes/ClearPassOnGuard/ClearPassOnGuard.pkg -target /
hdiutil detach /Volumes/ClearPassOnGuard
Above command can be added to a script and that script can be executed. Note that in first command you need to give complete path of ClearPassOnGuardInstall.dmg file.
