-Module Name:
- ginastub.c
-
-Abstract:
- This sample illustrates a pass-thru "stub" gina which can be used
- in some cases to simplify gina development.
-
- A common use for a gina is to implement code which requires the
- credentials of the user logging onto the workstation. The credentials
- may be required for syncronization with foreign account databases
- or custom authentication activities.
-
- In this example case, it is possible to implement a simple gina
- stub layer which simply passes control for the required functions
- to the previously installed gina, and captures the interesting
- parameters from that gina. In this scenario, the existing functionality
- in the existent gina is retained. In addition, the development time
- is reduced drastically, as existing functionality does not need to
- be duplicated.
-
- When dealing with credentials, take steps to maintain the security
- of the credentials. For instance, if transporting credentials over
- a network, be sure to encrypt the credentials.
