The DesiredContextTime property indicates the time duration, in seconds, that the security context defined by the mechanism remain in effect.
The preset default value, “”, which indicates that there is no time limit on the security context, is the only valid setting for this property.
The DesiredContextTime property is not currently supported for any mechanism, but is reserved for future use.
Vantage standard mechanisms do not support a time limit on the security context. The system ignores any edits to the value of this property.
