LDAP authentication
LDAP-based I&A is configured in the "UNIX-type" authentication mode. In this mode, the administrative data (including user names, IDs, and passwords) are stored in LDAP where access to the data is limited to the LDAP administrator.
When a user logs into the system, the system binds to the LDAP server using the LDAP administrator account over an SSL connection, retrieves the necessary data for the user (including the password) from LDAP, and then performs authentication using the data retrieved from LDAP. The system maintains an administrative database on an LDAP server. The remaining hosts import the administrative data from the same LDAP server through the same mechanism previously described. The system maintains a consistent administrative database by making all administrative changes on the designated LDAP server. A user ID on any computer refers to the same individual on all other computers. In addition, the password configuration, name-to-UID mappings, and other data are identical on all hosts in the distributed system.
