Sun Java System Directory Server is the corporate directory server that is used to control access to all web-based applications. Pluggable Authentication Module (PAM) for LDAP authenticates and manages passwords on the SolarisTM Operating System (Solaris OS) against Directory Server passwords. The two preferred Directory Servers manage a single root suffix, dc=eb,dc=com, and all users are stored in the ou=people,dc=eb,dc=com container with uid as the naming attribute. The directory servers, installed on Solaris systems, are running on separate machines: master-east.eb.com and master-west.eb.com.
