An access control function is mapped to a digital signature. The digital signature is used to verify that an executable element retrieved for executing the access control function is the proper executable element. The access control functions may be invoked upon the occurrence of access control events, such as a user successfully logging onto an information access system or the modification of a user's password. A mapping contains data used to determine what events are tied to what access control functions, and whether the access control function should be executed. Upon the occurrence of an extension event that is tied to an extension, an executable element for the extension is retrieved. After executing an extension, data is returned to the caller of the extension. The returned d…
