Authentication

.LRN has and an internal database backed authentication infrastructure
in addition to external authentication mechanisms. It is possible to configure
multiple authentication authorities, which can be sorted accordingly. Presently
drivers for unix Pluggable Authentication Modules (PAM) (which allows the
system administrator to choose any number of authentication methods - e.g.
RADIUS, Kerberos, IMAP, POP, AFS, etc.) and LDAP have been created. The
dedicated .LRN LDAP module supports realtime user synchronization. The external
authentication infrastructure is modular so that additional authentication
drivers can be easily added in the future. User logins can be encrypted
with SSL. The system has an email password reminder and/or reset option,
which can be set for each authority. Passwords stored in the system database
are encrypted.
