[Building Sakai] Issues with Account Validator in Clustered Environment

[Mike Jennings]

Stephen,

Well I tested my scenario with the Administrative password reset and 
things worked just fine.  I then when back and did it with the account 
validator, and that worked just fine too.  So I don't know how I got it 
to reproduce the issue the way I did that one time, but we are having 
all kinds of crazy issues with one class in particular with this.

I am now lost again as to why this is happening as I do have issue 
reproducing it consistently.

Mike
