Configuration expressions

In the configuration, context data can be referenced with either variable expressions or with Java EL expressions.

Expressions can be used for the following configuration element attributes:

• Arg value (to be returned to the caller (nevisProxy])
• GUI label (to be passed to the login page renderer)
• property value (if an AuthState uses the mechanism, see AuthState documentation for details)

info

To debug variable handling, use the trace groups Vars and EL.

See also attribute hide in Authentication engine attributes. This attribute can be used to hide some variable values from logging.
