When CA AuthID(previously known as ArcotID) activex client or ANC(Arcot Native Client) is installed as domain administrator and registered the arcot user, the administrator is able to authenticate with the ArcotID on internet explorer. After that, when the login user is changed to a non domain administrator, the user is still able to authenticate using the ArcotID. However, when the user is added to the "Microsoft Roaming profile" in the domain definition, the user is no more able to authenticate with the ArcotID. The authentication fails even if the ArcotID is still present and reachable by the user. The ArcotID is stored in the %PUBLIC% folder so that it is visible by all the users accessing the workstation.
If the user is promoted to domain administrator, the ArcotID authentication is again successful.
