+This directory contains a slapd overlay, allop.
+The intended usage is as a global overlay for use with those clients
+that do not make use of the RFC3673 allOp ("+") in the requested
+attribute list, but expect all operational attributes to be returned.
+Usage: add to slapd.conf(5)
+
+moduleload path/to/allop.so
+
+overlay allop
+allop-URI <ldapURI>
+
+if the allop-URI is not given, the rootDSE, i.e. "ldap:///??base",
+is assumed.
+
+Use Makefile to compile this plugin or use a command line similar to:
+
+gcc -shared -I../../../include -I../../../servers/slapd -Wall -g \
+ -o allop.so allop.c

+.SH NAME
+slapo-allop \- All Operational Attributes overlay
+.SH SYNOPSIS
+ETCDIR/slapd.conf
+.SH DESCRIPTION
+The All Operational Attributes overlay is designed to allow slapd to
+interoperate with dumb clients that expect all attributes, including
+operational ones, to be returned when "*" or an empty attribute list
+is requested, as opposed to RFC2251 and RFC3673.
+.SH CONFIGURATION
+These
+.B slapd.conf
+options apply to the All Operational overlay.
+They should appear after the
+.B overlay
+directive and before any subsequent
+.B database
+directive.
+.TP
+.B allop-URI <ldapURI>
+Specify the base and the scope of search operations that trigger the overlay.
+By default, it is "ldap:///??base", i.e. it only applies to the rootDSE.
+This requires the overlay to be instantited as global.
+
+.SH EXAMPLES
+.LP
+default behavior: only affects requests to the rootDSE
+.nf
+ # global
+ overlay allop
+.fi
+.LP
+affects all requests
+.nf
+ # global
+ overlay allop
+ allop-URI "ldap:///??sub"
+.fi
+.LP
+affects only requests directed to the suffix of a database
+.nf
+ # per database
+ database bdb
+ suffix "dc=example,dc=com"
+ # database specific directives ...
+ overlay allop
+ allop-URI "ldap:///dc=example,dc=com??base"
+.fi
