Review Comment: Verified fixed in 843a631e: both locales now qualify the enumeration claim with `consumer_required=false` and explain the default Consumer mapping requirement. ########## docs/en/latest/plugins/ldap-auth-advanced.md: ########## @@ -0,0 +1,283 @@ +--- +title: ldap-auth-advanced +keywords: + - Apache APISIX + - API Gateway + - Plugin + - LDAP Authentication + - ldap-auth-advanced +description: The ldap-auth-advanced Plugin authenticates users against an LDAP directory using search-then-bind, so users do not need to be enumerated in APISIX. +--- + +<!-- +# +# Licensed to the Apache Software Foundation (ASF) under one or more +# contributor license agreements.

Unlike [`ldap-auth`](./ldap-auth.md), which binds with a DN assembled from the Consumer configuration, this Plugin *searches* the directory for the user first, then binds as the entry it found. Users therefore do not need to be enumerated in APISIX. + +On each request the Plugin: + +1. Reads the credentials from the `Proxy-Authorization` header, falling back to `Authorization`. +2. Searches `base_dn` for the entry whose `attribute` matches the supplied username, then binds as that entry with the supplied password. +3. Attaches a matching [Consumer](../terminology/consumer.md), unless `consumer_required` is `false`. + +The credential header uses the scheme word given by `header_type`, which defaults to `ldap` rather than `basic`, so the default expects `Authorization: ldap <base64(username:password)>`. Set `header_type` to `basic` to accept ordinary [basic access authentication](https://en.wikipedia.org/wiki/Basic_access_authentication) instead. + +The Plugin distinguishes two failure modes, so an outage is never reported as a rejected credential: + +| Status | Cause | +|--------|-------| +| `401` | Missing, malformed, or rejected credentials; a username matching more than one entry; or `consumer_required` is `true` and no Consumer matches. Returned with a `WWW-Authenticate` header. | +| `500` | The directory is unreachable or the `bind_dn` credentials were rejected. | Review Comment: Verified fixed in 843a631e: both locales now cover LDAP transport, TLS, protocol, search, server-result, and `bind_dn` credential failures. -- This is an automated message from the Apache Git Service.
