[Zope-dev] Unable to retrieve member data

[Priya Ramkumar]

Hi all,

I am using Zope2.3.3 & CMF1.1 with ZEO1.0b3. The CMF site was working fine
all through. But suddenly, there is a problem in authenticating users. That
is, whenever a method such as
portal_membership.getAuthenticatedMember().getMemberId()" or
"portal_membership.getAuthenticatedMember().getUserName()" is invoked from a
DTML method,  I get the following error message.

Error Type: MemberDataError
Error Value: Can't find user data.

Also, "portal_membership.isAnonymousUser()" returns 0. I also checked that
portal_membership.getAuthenticatedMember()" returns the member.  But I am
surprised that I am unable to get the attributes of the member object like
name or id. Has anyone faced this sort of problem? Or does anyone know under
what circumstances such functions as getMemberId(), getUserName() returns an
error?

Thanks for any help & suggestions.

This is the traceback I get.
