7.4 Blocking the user login with the <strong>opsi</strong>-Loginblocker<br />
To prevent a user login before all installations are completed, <strong>opsi</strong> provides the optional <strong>opsi</strong>-login-blocker.<br />
7.4.1 <strong>opsi</strong> loginblocker at Windows 2000 to XP (NT 5)<br />
74 / 193<br />
The <strong>opsi</strong>-login-blocker is implemented as the Gina <strong>opsi</strong>gina.dll. Gina means Graphical Identification and Authentication<br />
and is the official Microsoft hook to manipulate the login process.<br />
If you already have a special Gina-DLL installed, which is different from the original Microsoft msgina.dll (e.g.<br />
Novell nwgina.dll), you should not install the <strong>opsi</strong>-login-blocker without consulting <strong>uib</strong> or https://forum.<strong>opsi</strong>.org. It<br />
is possible to chain different gina.dll’s, but therefore the installation has to be customized. Proper chaining of Gina<br />
DLLs is a quite critical task and might result in a locked up computer if done improperly.<br />
Whether the <strong>opsi</strong>-login-blocker is installed or not is configured by the switch LoginBlockerStart=on/off in section<br />
[<strong>opsi</strong>-client-agent-install] of the client configuration.<br />
7.4.2 <strong>opsi</strong> loginblocker at NT 6 (Win 7 & Co)<br />
The <strong>opsi</strong>-login-blocker at Vista is implemented as a credential provider filter. It blocks all credential providers until<br />
the release by the <strong>opsi</strong>clientd or timeout.
