Yes we are in the same situation.
With V9.1.3 EBI, we had a limited roll-out of Add-In for MS Office. These users needed to host-authenticate to LINUX via PAM / POSIX to LDAP before being able to use the product in Excel.
Our network people have now automated the creation of POSIX attributes, we are still nervous about rolling this software out to 500-1000 desktops.
With V9.2, there are different authentication methods. We haven't looked at AMO for V9.2 yet, but will soon.
