In this multisite for joomla 1.2.9 version we have fixa bug when computing the cookie_domains that is used by the single sign-in.
In fact the detection of the physical shared table name was incorrectly computed that has resulted to put two dbname in front of the table name.
The consequence was a bad users table relationship detection and therefore JMS concluded that users are independents (and not shared).

We also have bundled this version with the Patch Definition 1.2.12 that:

• Add a patch definition for JRECache.
• Add JMS Tools (install) definitions for :
  JRECache, DTRegister, JConnect, JIncludes, several modules and plugins for fabrik, SuperFishMenu, ALinkExchanger
