NAME

6       slapo-retcode - return code overlay to slapd
7

SYNOPSIS

9       /etc/openldap/slapd.conf
10

DESCRIPTION

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
16       The error responses are generated according to different strategies.
17
18       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
24       Well-known response codes from standard track documents are provided in
25       retcode.conf, which can be included after instantiating the overlay.
26
27       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
32       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
36       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
41       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
46       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
51       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
71       retcode-indir
72              Enables exploitation of in-directory stored  errAbsObject.   May
73              result in a lot of unnecessary overhead.
74
75       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.

SCHEMA

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
88       The schema includes a number of object classes and associated attribute
89       types as described below.

91
92       The error code:

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