[Building Sakai] Issues with Account Validator in Clustered Environment

[Mike Jennings]

Hi all.  We are currently running Sakai 2.9.2 on about 8 tomcat servers. 
  The issue that we are currently running into is that when the user is 
using the Account Validation page to create there Local Account and set 
there password, this change only works on the server that they are 
currently connected to.  If the logout and then connect to a different 
application server, they get a login invalid message.

I was hoping that someone has run into this issue already..

Here is the quick rundown.

User connects to server 1 and does the account validation and sets there 
password.  They are able to logout and log back in with the new password 
as long as they are on server 1.

Later they reconnect but are attached to server 2.  They are not able to 
login to the system and get login invalid message.

If I login to server 2 as a administrator and evict all caches in the 
memory, then the user can login to server 2 with there validated 
username and password.

Please any help would be greatly appreciated...
