The PAU mechanisms involving InternalPrincipal and PrincipalInfo are internal to its workings. From what I can see, these shouldn't impact what you're doing. If you want the grimy details, look at the README.txt doctest file in zope/app/authentication. However, these mainly apply to plugin developers.
To store additional information for a principal, use the principal annotation utility. E.g. were you in a browser view: util = zapi.getUtility(IPrincipalAnnotationUtility) annotations = util.getAnnotations(self.request.principal) I would strongly discourage you from subclassing InternalPrincipal -- it's, well, internal :-) If annotations aren't working for you, give me the specifics and I'll see if I can help. -- Garrett > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf Of Alec Munro > Sent: Tuesday, August 23, 2005 10:06 AM > To: [EMAIL PROTECTED] > Cc: email@example.com > Subject: Re: [Zope3-Users] Confusion about PAU usage. > > On 8/22/05, Christoph Frick <[EMAIL PROTECTED]> wrote: > > On Mon, Aug 22, 2005 at 11:47:40AM -0300, Alec Munro wrote: > > > > > In my situation, I am trying to create principals with additional > > > properties, and initially I did that by extending > InternalPrincipal. > > > That worked fine, until I realised that when I > authenticated, I was > > > getting back a PrincipalInfo instance, which does not contain the > > > additional properties.
