10 The Translucent Proxy overlay can be used with a backend database such as
12 to create a "translucent proxy". Entries retrieved from a remote LDAP
13 server may have some or all attributes overridden, or new attributes
14 added, by entries in the local database before being presented to the
19 operation is first populated with entries from the remote LDAP server, the
20 attributes of which are then overridden with any attributes defined in the
21 local database. Local overrides may be populated with the
26 operations, the use of which is restricted to the root user.
30 operation will perform a comparison with attributes defined in the local
31 database record (if any) before any comparison is made with data in the
34 The Translucent Proxy overlay uses a remote LDAP server which is configured
35 with the options shown in
39 options are specific to the Translucent Proxy overlay; they must appear
45 By default, attempts to delete attributes in either the local or remote
46 databases will be silently ignored. The
48 directive causes these modifications to fail with a Constraint Violation.
50 .B translucent_no_glue
51 This configuration option disables the automatic creation of "glue" records
56 operation, such that all parents of an entry added to the local database
57 must be created by hand. Glue records are always created for a
61 .B translucent_local <attr[,attr...]>
62 Specify a list of attributes that should be searched for in the local database
63 when used in a search filter. By default, search filters are only handled by
64 the remote database. With this directive, search filters will be split into a
65 local and remote portion, and local attributes will be searched locally.
67 .B translucent_remote <attr[,attr...]>
68 Specify a list of attributes that should be searched for in the remote database
69 when used in a search filter. This directive complements the
71 directive. Attributes may be specified as both local and remote if desired.
77 are specified, the default behavior is to search the remote database with the
78 complete search filter. If only
80 is specified, searches will only be run on the local database. Likewise, if only
82 is specified, searches will only be run on the remote database. In any case, both
83 the local and remote entries corresponding to a search result will be merged
84 before being returned to the client.
88 The Translucent Proxy overlay will disable schema checking in the local database,
89 so that an entry consisting of overlay attributes need not adhere to the
92 Because the translucent overlay does not perform any DN rewrites, the local
93 and remote database instances must have the same suffix. Other configurations
94 will probably fail with No Such Object and other errors.
