Implement NPN_GetAuthenticationInfo
Project Member Reported by, Oct 6 2009 Back to list
This is used by the Java plugin.  Not sure how high-priority this is.

Talked to Ken a bit more.  The use case is for enterprises where it would be 
inconvenient for the user to have to keep signing in both for the page and for the 
applets in it.

CCing Glenn since this is an enterprise related feature.  This shouldn't take long to 
implement, just needs some plumbing, but I don't think I'll have time to get to it 
anytime soon.  Glenn: can you assign this to whoever joins the enterprise team?

Note: a test case for this functionality has been checked in under test/data/plugin/ . 
It requires some manual setup and intervention.

Missing implementation affects not only Java plugins, but convenient multibrowser firebreath plugins (

There are some life cases when plugin app needs users credentials, which have already been entered. Without working NPN_GetAuthenticationInfo  programmer needs to invent workarounds, like annoying login window or duplicating + crypting + storing credentials locally in register. In other words there is no way to access credentials except NPN_GetAuthenticationInfo.

At the same time Firefox & Opera implement NPN_GetAuthenticationInfo. 

My post related to the problem:

Patches welcome--it's not that we don't want this fixed, it's just not a priority for anyone at the moment.
please advice, how can I access HttpAuthCache object?
