Agreed.  But with current releases of Products.PluggableAuthService 
(until and including 1.7.2) no result is given back, so we cannot be 
sure here if there is no result because the PAS is too old or because it 
really failed.

With the proposed changes, either the created user or None is returned, 
which you might consider an API change.  At least I mention in the 
interface in AccessControl that implementations should return the 
created user or None.

That's the general idea.

I committed the changes on Zope2 trunk and branch 2.13, AccessControl 
trunk, and Products.PluggableAuthService trunk (used by Plone 4.0 and 
4.1).  Note that Zope2 2.13 also uses AccessControl trunk and in fact 
there are no official branches of that.

Note that in the do_adduser method that is used in 'bin/zopectl adduser' 
I used shorter output as that code gets printed on the command line so 
it should be very simple.  It either prints "Created user joe" or 
"Created user None".


Cheers,
