PIX: How to disable uauth logout feature?

[vidals]

Hi.

Anybody knows how to disable following feature which gives useless headache to my users on PIX 6.2?

<<<<<If a user wishes to log out and clear their entry in the PIX Firewall uauth cache, the user can again Telnet to the virtual address. The user is prompted for their username and password, the PIX Firewall removes the associated credentials from the uauth cache, and the user will receive a "Logout Successful" message.>>>>>

Thanks.

This is a security feature, disabling this might give free access to users who are not supposed to have access in the first place. The command to twidle with uauth timeouts is "timeout uauth". For command usage see the following URL,

Thanks Sam. Yes, it is a way to disable logout prompt but for security reason, let people authenticated for ever is not acceptable.

Well it doesn't look possible then.
