[Zope3-Users] request/principal and PAU users

Hi,

I've implemented a site that uses both Principal (for external users)and 
PAU (for intranet users).

It use a customized skin and in the template.pt file I want to print out 
  the username.

The following line works if I'm connected as an external user (defined 
in principals.zcml)

	<b tal:context="request/principal/title">User</b>

but it raise an error when I'm connected as a PAU user.

	ForbiddenAttribute: ('id', Principal(u'ldap.tonon'))


I attached the complete Traceback error I get.

Please, does anyone have a solution?

Thank you,
Riccardo
