Reba,I'm still struggling with just logging in.
Reba,
Log in with "remember me" checked and browse for a while and when done then log out then try again without "remember me" checked and it should clear up...
as for me I log in wihtout "remember me" checked and still logged in as long I am browsing AD just fine..
but before you do these tip, clear your cookie first (just AD specific cookies ) to see if it lets you stay logged in. If not then do the tip above.
