6 slapo-retcode - return code overlay to slapd
7
9 /etc/openldap/slapd.conf
10
12 The retcode overlay to slapd(8) is useful to test the behavior of
13 clients when server-generated erroneous and/or unusual responses occur,
14 e.g. error codes, referrals, excessive response times and so on.
15 The error responses are generated according to different strategies.
17 In the first case, all operations targeted at a specific configurable
19 subtree cause the object related to the request DN to be looked up and
20 checked for return code data: a response code, plus an optional textual
21 message, an optional configurable delay, an optional matched DN field,
22 and, when the response code is "referral", a (list of) referral(s).
23 Well-known response codes from standard track documents are provided in
25 retcode.conf, which can be included after instantiating the overlay.
26 In the second case, objects of classes inherited from the errAbsObject,
28 like errObject or errAuxObject, when returned as intermediate responses
29 of a search request, are changed into the response dictated by their
30 content.
31 A third mode causes objects to be looked up from the underlying data‐
33 base to discover if their class inherits from errABsObject; in that
34 case, their content is used to compute the corresponding response.
35 The behavior is disabled by using the manageDSAit control (RFC 3296);
37 in that case, the resulting object, either present in the directory or
38 dynamically generated by the overlay, or contained in the request, is
39 handled as usual.
40 The config directives that are specific to the retcode overlay must be
42 prefixed by retcode-, to avoid conflicts with directives specific to
43 the underlying database or to other stacked overlays. The following
44 specific directives can be used to configure the retcode overlay:
45 retcode-parent <DN>
47 This directive defines the parent DN where dynamically generated
48 entries reside. If not defined, the suffix of the database is
49 used.
50 retcode-item <RDN> <errCode> [op=<oplist>] [text=<message>]
52 [ref=<referral>] [sleeptime=<sec>] [matched=<DN>]
53 [unsolicited=<OID>[:<data>]] [flags=[pre|post-]disconnect[,...]]
54 A dynamically generated entry, located below retcode-parent.
55 The errCode is the number of the response code; it can be in any
56 format supported by strtol(3). The optional oplist is a list of
57 operations that cause response code generation; if absent, all
58 operations are affected. The matched field is the matched DN
59 that is returned along with the error, while the text field is
60 an optional diagnostics message. The ref field is only allowed
61 for the referral response code. The sleeptime field causes
62 slapd(8) to sleep the specified number of seconds before
63 proceeding with the operation. The unsolicited field can be
64 used to cause the return of an RFC 4511 unsolicited response
65 message; if OID is not "0", an extended response is generated,
66 with the optional data appended. If flags contains disconnect,
67 or pre-disconnect, slapd(8) disconnects abruptly, without
68 notice; post-disconnect causes disconnection right after sending
69 response as appropriate.
70 retcode-indir
72 Enables exploitation of in-directory stored errAbsObject. May
73 result in a lot of unnecessary overhead.
74 retcode-sleep [-]<n>
76 Defines a sleep time in seconds that is spent before actually
77 handling any operation. If negative, a random time between 0
78 and the absolute value of the argument is used.

82 The retcode overlay utilizes the "return code" schema described herein.
83 This schema is specifically designed for use with this overlay and is
84 not intended to be used otherwise. It is also noted that the schema
85 described here is a work in progress, and hence subject to change
86 without notice. The schema is loaded automatically by the overlay.
87 The schema includes a number of object classes and associated attribute
89 types as described below.
90 The error code:
93 ( 1.3.6.1.4.1.4203.666.11.4.1.1
94 NAME ( 'errCode' )
95 DESC 'LDAP error code'

100 The operations that trigger the response code:

117 The sleep time before the response is actually returned to the client:

133 The OID to be returned as extended response OID in RFC 4511 unsolicited
135 responses ("0" generates a regular response with msgid set to 0):

142 The octet string to be returned as extended response data in RFC 4511

148 SYNTAX 1.3.6.1.4.1.1466.115.121.1.40

150 If TRUE, slapd(8) disconnects abruptly without notice; if FALSE, it
152 disconnects after sending response as appropriate:
