[z3-five] objects, security,etc

[kevin7kal]

Maybe opening a tgz is more of a hassle for some.  So I will cut and 
paste my code and hopefully someone can point out my errror.
I create a 'Zclass2' object through the zmi and try this 'Script(Python)'

MZ = context.Zclass2
#print MZ.attribute1b.method1()
print MZ.attribute1b
print MZ.attribute1a
return printed

if I uncomment line 2, it fails with unauthorized to access attribute 
'attribute1b'
