Description (partial)

When using the IP admission feature on an ISR, users may authenticate with their workstation hostname instead of their Active Directory user credentials when authenticating via NTLM.  This will cause them to show up in the Cisco Cloud Web Security portal as their workstation name (WORKSTATION_NAME$) instead of their username (jsmith).

1.  The workstation has an application, service, or script that generates HTTP traffic prior to a user logging onto the workstation

2.  The ISR is configured for NTLM authentication

3.  The base-dn in the LDAP configuration on the ISR includes the entire AD directory so that the LDAP searches for the computer name are successful and therefore the LDAP authentication request is successful
