Installing and Enabling Single Sign-on
Installing and Enabling Single Sign-on on Windows
Installing RGS Single Sign-on is for experienced users and IT administrators only.
Please read all the directions completely before proceeding and exercise caution
when installing.
The RGS shared library, hprgina.dll, enables Single Sign-on. The file hprgina.dll
is a GINA (Graphical Identification and Authentication) module that is loaded by the
Window's WinLogon.exe process. There are three ways to install and enable RGS
Single Sign-on.
1. Install time:
The hprgina.dll can be installed and enabled during the RGS Sender installation.
This is the preferred method and is the safest and easiest way to enable RGS Single
Sign-on. The default during installation is to not enable Single Sign-on. The user
must answer two questions before Single Sign-on is properly enabled. If enabled, the
system must be rebooted before RGS Single Sign-on is operational.
2. Using the rgadmin Tool:
The RGS Rgadmin Tool can be used to enable or disable the hprgina.dll. The
rgadmin
tool can also be run from the command line with the proper options to
enable or disable the GINA module. This method is preferred over the manual
method.
3. Manual Method:
Although this is not the preferred method to enable RGS Single Sign-on, it is here so
that administrators will know exactly what parts of the system are modified. To
manually enable WinLogon to load the hprgina module, do the following steps in the
exact order listed:
1. Install the RGS Sender on the HP Workstation. If the RGS Sender is not
installed or installs with errors, DO NOT perform the remaining steps. Doing
so puts the system in a state that requires a complete re-installation of the
operating system.
2. After the RGS Sender is installed confirm that the hprgina.dll exists in the
C:\WINDOWS\system32 directory. The RGS Sender installer copies
hprgina.dll into the system32 directory directly. If it does not exist, DO
NOT perform the remaining steps. Doing so puts the system in a state that
requires a complete re-installation of the operating system.
3. Add the GinaDLL registry key if it does not already exist. This can be done
through the use of regedit, the Windows Registry Editor. Create the key as
type REG_SZ (a string type). The full path of the key is
