What it does
Extends WU-FTPD so user records and passwords can be resolved and checked through LDAP.
Why it mattered
It allowed the same directory-backed identity model to be used for both web and FTP access in extranet-style deployments.
What to read first
Start with the README for build requirements, ftpaccess configuration, and the expected LDAP schema and attributes.

Notes
How the LDAP integration worked
Design
System users first, LDAP second
The patched daemon first keeps the normal WU-FTPD behavior for anonymous and system users. If that lookup fails, it falls back to LDAP and builds a standard struct passwd from the directory data.
Configuration
ftpaccess drives the connection
LDAP host, port, base DN, bind user, and bind password are configured through new ftpaccess directives such as ldap-host, ldap-port, and ldap-base.
Schema expectations
Directory-side requirements
Users are looked up with uid=username and are expected to have attributes such as uidNumber, gidNumber, homeDirectory, and userPassword, with an ftpUser object class.
History
The original project context
This work came out of an extranet project that mixed web and FTP access. The README is still the authoritative source for the build path, OpenLDAP dependency notes, runtime behavior, and example session transcript.
