Hi,

 

is the user authenticated to the APM or is it before authentication?

 

If the user is already authenticated, are you sure webtop and ressources are assigned to the user?

 

If the user does not have any resource and webtop, the session is allowed in LTM-APM mode to the default pool member of the VS. if no pool is assigned, the F5 send a RST packet.
