To install the Security Connector in Sitecore you need the following:
It is possible to use Sitecore CMS 6.0.1 Rev. 090317 (Sitecore CMS 6.0.1 rev. 090212 plus the Sitecore CMS 6.0.1 Update rev. 090317 package)
If you have Sitecore DMS installed, you will need to back up your Analytics database before you install the S4S package.
IMPORTANT: Installation of a package that contains Site pages into Sitecore can cause an error in the Analytics database. Use the backup of the Analytics DB after successful S4S installation if required.
