In a heterogeneous data center, administering access and managing identity can be time-consuming any way you slice it. With user data scattered within metadirectories or elsewhere in a company, creating single sign-on techniques for disparate data is vexing for many IT departments.
Further complicating things, solutions for Linux authentication in heterogeneous data centers are legion. Finding the right fit can be as difficult as managing the problem itself. And as system administrators weigh the options, a central question is, Do any of the alternatives trump Microsoft's Active Directory (AD)?
Most metadirectory deployments synchronize data into at least one Lightweight Directory Access Protocol (LDAP) directory server to ensure that an LDAP application like single sign-on has access to recent data. System administrators can also create special LDAP directories for their Linux and Unix boxes. Big-box applications from IBM Corp., CA and Hewlett-Packard Co. are also available, but at a higher price point. Legacy approaches, such as Sun Microsystems' Network Information Service for password management, also exist, but experts warn that this approach often fails IT compliance regulations like the Sarbanes-Oxley Act (SOX).
