8 Click Put to push the configurations.
9 Click Close to return to the Appliances view, and then refresh the appliance status (Tools > Refresh 

Status). 

If you need to remove the ETEP from service and use it elsewhere, you need to disable strict 
authentication and remove all certificates and policies. 

To disable strict authentication: 
1 In the Appliance Manager, right-click on the PEP and select Configuration.
2 In the Configuration editor, click the Features tab.
3 Clear the Enable Strict Client Authentication box.

If certificates expire or if you enable strict authentication before installing certificates, you might not be 
able to communicate with the ETEP from the management workstation. In this case, you can connect a 
serial cable to the ETEP and disable strict authentication from the command line.

To disable strict authentication from the command line:
1 Connect to the serial port of the appliance and open a terminal session.
2 Log in and type 

 to enter configuration mode.

3 Type 

 to enter management interface configuration mode.

4 Enter 

.

For example: 

admin> configure

Entering configuration mode...

config> management-interface

Entering management interface configuration mode...

man-if> strict-client-authentication disable

For more information about using the 

strict-client-authentication

 command, see the CLI User 

Guide for the ETEP.

When you remove all certificates, the appliance regenerates a self-signed certificate. This operation can 
be performed from the EncrypTight software running on the management workstation, or from a 
command line window. For information on using the CLI commands, see the ETEP CLI User Guide.
