Linux PAM to LDAP Authentication Migration

Authentication of Linux system users are maintained by PAM (Plugable Authentication Module). LDAP (Lightweight Directory Access Protocol) is used to replace the local user account authentication. Our existing environment uses PAM through Dovecot POP3 and RADIUS for authen-tication.This research focuses on the implementation of LDAP as an authentication service and migration of accounts and applications. Implementation and migration using account data that is using P AM. An application is also developed to search and modify existing account, and creating new account. Based on test performed, the account migration is successful. Testing the migrated accounts were performed. Also response time that is needed by LDAP to authenticate is shorter than the existing system which uses POP3 and RADIUS.
