From the module README:
----------------------------------
This module enables you to use external authentication sources for password
verification. At the moment this module has 2 drivers. One for LDAP and
one for IMAP which also supports POP3. TLS/SSL are supported for both drivers.
When you use this module you will still need to create accounts within
SilverStripe. There will be an extra field for each account, specifying the
username in the external authentication source.
If you run your website at your ISP which also hosts your mailbox, you can use
the ISP's IMAP/POP3 server to validate your logon. Other users at the ISP
cannot login when you do that, because the accounts also need to be registered
within SilverStripe.
---------------------------------
This topic is continued from the "LDAP Support for SilverStripe" thread from 'Contributions'.
This module was originally released as an LDAP authenticator and then renamed to Simple Authenticator when IMAP/POP3 capabilities were added. Since the name was confusing, it is now renamed to External Authenticator. Updates with respect to the previous version:
- Renamed the module
- Added internationalization
- Code layout cleanup
