The User Database (UDB) API provides functions for dealing with users and groups belonging to the currently selected provider (WinGate UDB, Active Directory or Windows UDB). It provides functions for

• Querying objects (users and groups)
• Performing searches of the UDB
• Testing user membership
• Authentication enumeration
• Extension of user objects with custom data
• Encryption of data to/from users

Authenticating Users

• Open an authentication process with UDBAuthOpen
• Step though the process with UDBAuthStepBinary and/or UDBAuthStepBase64
• When finished get the resulting user with UDBAuthGetAuthenticatedUser

UDB Extenders

UDB Extenders allow you to attach custom data onto UDB objects. You provide a set of standard functions for managing the lifetime and storage of the data and the framework calls your functions when required.
