7 slapo\-retcode \- return code overlay to slapd
15 is useful to test the behavior of clients when server-generated erroneous
16 and/or unusual responses occur, e.g. error codes, referrals,
17 excessive response times and so on.
19 The error responses are generated according to different strategies.
21 In the first case, all operations targeted at a specific configurable
22 subtree cause the object related to the request DN to be looked up
23 and checked for return code data: a response code, plus an optional
24 textual message, an optional configurable delay, an optional matched DN
25 field, and, when the response code is "referral", a (list of) referral(s).
27 Well-known response codes from standard track documents are provided
28 in \fBretcode.conf\fP, which can be included after instantiating
31 In the second case, objects of classes inherited from
32 the \fBerrAbsObject\fP, like \fBerrObject\fP or \fBerrAuxObject\fP,
33 when returned as intermediate responses of a search request, are changed
34 into the response dictated by their content.
36 A third mode causes objects to be looked up from the underlying database
37 to discover if their class inherits from \fBerrABsObject\fP;
38 in that case, their content is used to compute the corresponding response.
40 The behavior is disabled by using the \fBmanageDSAit\fP control (RFC 3296);
41 in that case, the resulting object, either present in the directory
42 or dynamically generated by the overlay, or contained in the request,
45 The config directives that are specific to the
47 overlay must be prefixed by
49 to avoid conflicts with directives specific to the underlying database
50 or to other stacked overlays. The following specific directives
51 can be used to configure the retcode overlay:
53 .B retcode\-parent <DN>
54 This directive defines the parent DN where dynamically generated
56 If not defined, the suffix of the database is used.
59 .B retcode\-item <RDN> <errCode> [op=<oplist>] [text=<message>]
60 .B [ref=<referral>] [sleeptime=<sec>] [matched=<DN>]
61 .B [unsolicited=<OID>[:<data>]] [flags=[{pre|post}\-]disconnect[,...]]
63 A dynamically generated entry, located below \fBretcode\-parent\fP.
64 The \fBerrCode\fP is the number of the response code;
65 it can be in any format supported by
67 The optional \fBoplist\fP is a list of operations that cause
68 response code generation; if absent, all operations are affected.
69 The \fBmatched\fP field is the matched DN that is returned
70 along with the error, while the \fBtext\fP field is an optional
72 The \fBref\fP field is only allowed for the \fBreferral\fP
74 The \fBsleeptime\fP field causes
76 to sleep the specified number of seconds before proceeding
78 The \fBunsolicited\fP field can be used to cause the return
79 of an RFC 4511 unsolicited response message; if \fBOID\fP
80 is not "0", an extended response is generated, with the optional
82 If \fBflags\fP contains \fBdisconnect\fP, or \fBpre\-disconnect\fP,
84 disconnects abruptly, without notice; \fBpost\-disconnect\fP
85 causes disconnection right after sending response as appropriate.
89 Enables exploitation of in-directory stored errAbsObject.
90 May result in a lot of unnecessary overhead.
92 .B retcode\-sleep [\-]<n>
93 Defines a sleep time in seconds that is spent before actually handling
95 If negative, a random time between 0 and the absolute value of the argument
101 overlay utilizes the "return code" schema described herein.
102 This schema is specifically designed for use with this
103 overlay and is not intended to be used otherwise.
104 It is also noted that the schema described here is
107 and hence subject to change without notice.
108 The schema is loaded automatically by the overlay.
110 The schema includes a number of object classes and associated
111 attribute types as described below.
