<br>Dear All,<br><br>I
need help with dot1x implementation in an Enterprise LAN. Our target is
to authenticate and authorize users based on their identities (domain
user names) as well as applying GPOs on users.<br><br>Our authentication Backend is: Active Directory
<br>Our Authorization & Accounting is done by: freeRADIUS<br>Authorization Attributes control VLAN assignment (hence, IP address pool)<br>Required Authentication EAP-Type : PEAP & MS-CHAP<br><br>All
Clients are using WinXP supplicant. I managed to implement
PEAP&MS-CHAP with this setup however with users who have cached
credentials on their PCs. If the user logs on the PC for the first
time, he fails to reach the active directory to authenticate since the
connection is not yet authorized. So what I need is get the computer
authenticated and assigned an IP address and then authenticate the
user in a following phase while the connection is up.
<br><br>Any clues with authenticating domain machines using freeradius and active directory implementation?
