I understand there probably isn't a setting within SharePoint to accomplish this but figured this is a good place to ask.I need to force passwords for a portal to not be cached on users machines. Ever.What would be the best way to accomplish this?

I guess in the internet browser, tools -> internet options -> security -> custom level -> User Authentication -> logon -> select "Promp for user name and password".this way it will always ask for credentials.

You may be able to enforce that setting at the domain level by setting a group policy: http://blogs.technet.com/askperf/archive/2007/07/06/overview-of-internet-explorer-group-policies.aspx Hope it helpsEnrique Blanco PMP, Consultant www.eblanco.com www.wandau.com

We cannot modify the users computers so the first option will not work. I'm not sure if Group Policies would work either because we do not want this to apply to the entire portal/domain.We only want to modify it for 30-40 users. Any other ideas?

You can apply them to an specific OU... Since it is a client issue, you have little alternatives...Enrique Blanco PMP, Consultant www.eblanco.com www.wandau.com

I understand. Thanks for the help.

Hi, I think the group policy will invalid if the client users use other browser. Also, the Windows Authentication of SharePoint identifies the users in terms of the WindowsPrincipal after the first time logon. So never mind if you worry about the security of the credentials. You also can use Form Authentication of SharePoint. It identifies the users in according to the cookie or URL with expired time but caching the credentials.
