.SH NAME
-slapo-translucent \- Proxy Override overlay
+slapo\-translucent \- Translucent Proxy overlay to slapd
.SH SYNOPSIS
ETCDIR/slapd.conf
.SH DESCRIPTION
-The Proxy Override overlay can be used with a backend database such as
-.BR slapd-bdb (5)
+The Translucent Proxy overlay can be used with a backend database such as
+.BR slapd\-bdb (5)
to create a "translucent proxy". Entries retrieved from a remote LDAP
server may have some or all attributes overridden, or new attributes
added, by entries in the local database before being presented to the
database record (if any) before any comparison is made with data in the
remote database.
.SH CONFIGURATION
-The Proxy Override overlay uses a remote LDAP server which is configured
-with the options shown in
-.BR slapd-ldap (5).
+The Translucent Proxy overlay uses a proxied database,
+typically a (set of) remote LDAP server(s), which is configured with the options shown in
+.BR slapd\-ldap (5),
+.BR slapd\-meta (5)
+or similar.
These
.B slapd.conf
-options are specific to the Proxy Override overlay; they may appear anywhere
+options are specific to the Translucent Proxy overlay; they must appear
after the
.B overlay
-directive and before any subsequent
-.B database
-directive.
+directive that instantiates the
+.B translucent
+overlay.
.TP
.B translucent_strict
By default, attempts to delete attributes in either the local or remote
must be created by hand. Glue records are always created for a
.B modify
operation.
+.TP
+.B translucent_local <attr[,attr...]>
+Specify a list of attributes that should be searched for in the local database
+when used in a search filter. By default, search filters are only handled by
+the remote database. With this directive, search filters will be split into a
+local and remote portion, and local attributes will be searched locally.
+.TP
+.B translucent_remote <attr[,attr...]>
+Specify a list of attributes that should be searched for in the remote database
+when used in a search filter. This directive complements the
+.B translucent_local
+directive. Attributes may be specified as both local and remote if desired.
+.LP
+If neither
+.B translucent_local
+nor
+.B translucent_remote
+are specified, the default behavior is to search the remote database with the
+complete search filter. If only
+.B translucent_local
+is specified, searches will only be run on the local database. Likewise, if only
+.B translucent_remote
+is specified, searches will only be run on the remote database. In any case, both
+the local and remote entries corresponding to a search result will be merged
+before being returned to the client.
+
+.TP
+.B translucent_bind_local
+Enable looking for locally stored credentials for simple bind when binding
+to the remote database fails. Disabled by default.
+
+.TP
+.B translucent_pwmod_local
+Enable RFC 3062 Password Modification extended operation on locally stored
+credentials. The operation only applies to entries that exist in the remote
+database. Disabled by default.
+
+.SH ACCESS CONTROL
+Access control is delegated to either the remote DSA(s) or to the local database
+backend for
+.B auth
+and
+.B write
+operations.
+It is delegated to the remote DSA(s) and to the frontend for
+.B read
+operations.
+Local access rules involving data returned by the remote DSA(s) should be designed
+with care. In fact, entries are returned by the remote DSA(s) only based on the
+remote fraction of the data, based on the identity the operation is performed as.
+As a consequence, local rules might only be allowed to see a portion
+of the remote data.
+
.SH CAVEATS
.LP
-The Proxy Override overlay will disable schema checking in the local database,
+The Translucent Proxy overlay will disable schema checking in the local database,
so that an entry consisting of overlay attributes need not adhere to the
complete schema.
