Abstract: A spindle nut retainer is used with a spindle with a flat portion on its threaded end. The flat portion interrupts the threads on the threaded end. A washer with a mating flat portion is slidably mounted over the threaded end and a nut is removably threaded to the threaded end of the spindle against the washer to set the preload on bearings. The nut retainer overlays a plurality of the corners of the nut and engages the threaded portion of the spindle with tangs. A majority of the tangs are flexed or bent to remain in biased contact with the threads on the spindle. Some of the tangs are located over the flat portion and remain unbent. The tangs resist rotation of the nut by engagement with the flat portion where it meets the threads.

Abstract: A single sign-on (SSO) mechanism to enable a given user to access a target application on a target resource in a distributed computer enterprise. One or more configuration directives each identifying a given logon process and any associated methods required to access the target application on the target resource are stored in a preferably global-accessible database (CIM). For each of a set of users, a preferably global-accessible database (PKM) stores user-specific and application-specific information enabling the user to access and logon to one or more target resources. During a particular session, a logon coordinator (LC) mechanism coordinates given user information with the configuration directive to enable the given user to perform a given action with respect to the target application without specifying the given logon process and the application-specific information.
