Is there a way to have SharePoint automatically log off users after they have been idle for a specified amount of time? I have a site that utilizes NTLM, Windows Authentication and after 30 minutes of inactivity, it is not currently logging out users. I have tried setting IIS session timeout, SharePoint session timeout, SQL connection timeout in the web.config, and nothing has worked thus yet.

Hi, There is a setting at web application which will keep security validation for 30 mins by default and then if users tries to access the site. user will get a security prompt. Setting can be found in Central Administration -->Application management --> Web Application general settings under SharePoint Web Application Management. Thanks, Amish TrivediAmish Trivedi
