Claim of US Patent No. 9,461,980

1. A method comprising:
receiving, by a network access control (NAC) device and from a client device, a request for access to a network, wherein the
request includes a device identifier for the client device;

predicting, by the NAC device and based on the device identifier and a device usage history of the client device, a user assumed
to be making the request;

prior to completing a user authentication process, requesting, by the NAC device and from a directory server, session attributes
for the predicted user;

receiving, by the NAC device and from an authentication server, an indication of whether a user associated with the client
device was successfully authenticated;

determining, by the NAC device and based on an identifier of the user, whether the predicted user is the user associated with
the client device; and

responsive to determining that the predicted user is the user associated with the client device, establishing, by the NAC
and using the session attributes for the predicted user, a session between the client device and the network.
