The decision to use Active Directory came after Dell launched a project called Multi-Platform Management Integration (MPMI). Its goal was to make the Microsoft Active Directory directory service the authoritative authentication system and master source for all user accounts across all systems within Dell—those running Microsoft Windows, IBM AIX, Sun Solaris, and the various Linux operating systems. Dell chose not to create yet another directory or build a synchronization solution - they chose to consolidate and simplify their identity management infrastructure.
Dell has about 2,200 Linux and UNIX servers that they have now integrated with Active Directory. Dell tried the open source approach but, in the end, decided on a commercial solution. After evaluating and eliminating the competition they chose Quest. According to Dell, "One solution quickly rose to the top"...
“Vintela Authentication Services is the best product we have found on the market,” concludes David Taylor, Principal Linux engineer at Dell. “It satisfies our needs and can help us expand where we need to in the future.”
