Renaming a user

[David Demner]

I have a minor issue with Turbine security.  I can't rename a user; when I
go:
 
                 User user = TurbineSecurity.getUser(oldLoginName);
                 user.setName(newLoginName);
                 TurbineSecurity.saveUser(user);
 
I get an org.apache.turbine.util.security.UnknownEntityException: Unknown
user 'newLoginName'
 
Is there any workaround (other than creating a new user object, copying all
the properties/groups/roles individually, saving this user, and deleting the
old user)?
 
Thanks,
