 ### Pleroma.Web.Auth.Authenticator

 * `Pleroma.Web.Auth.PleromaAuthenticator`: default database authenticator.
+* `Pleroma.Web.Auth.LDAPAuthenticator`: LDAP authentication.
+
+### :ldap
+
+Use LDAP for user authentication.  When a user logs in to the Akkoma
+instance, the name and password will be verified by trying to authenticate
+(bind) to an LDAP server.  If a user exists in the LDAP directory but there
+is no account with the same name yet on the Akkoma instance then a new
+Akkoma account will be created with the same name as the LDAP user name.
+
+* `enabled`: enables LDAP authentication
+* `host`: LDAP server hostname
+* `port`: LDAP port, e.g. 389 or 636
+* `ssl`: true to use SSL, usually implies the port 636
+* `sslopts`: additional SSL options
+* `tls`: true to start TLS, usually implies the port 389
+* `tlsopts`: additional TLS options
+* `base`: LDAP base, e.g. "dc=example,dc=com"
+* `uid`: LDAP attribute name to authenticate the user, e.g. when "cn", the filter will be "cn=username,base"
+
+Note, if your LDAP server is an Active Directory server the correct value is commonly `uid: "cn"`, but if you use an
+OpenLDAP server the value may be `uid: "uid"`.
