good morning at all, i have a 802.1x infrastructure with dynamic vlan assignment for user authentication. When a PC is turned on, if the PC is computer group members of AD, then the computer is placed in a particular vlan (for example tag 137). When the user make login is moved to the correct vlan (for example 103). The problem is when user make logout. The computer remake authentication and it's moved on its vlan (137) but windows doesn't remake an ip renew. If a new user (never logged in this computer) tries to login, he can't finisch successfully the login because the computer hasn't an ip address to reach the Active Directory. Someone knows how to solve this problem??? Regards PS: I'm using freeradius 3 and passchange module works very fine. -- *Davide Garofalo*
