The following specific directives +can be used to configure the retcode overlay: +.TP +.B retcode\-parent +This directive defines the parent DN where dynamically generated +entries reside. +If not defined, the suffix of the database is used. +.HP +.hy 0 +.B retcode\-item [op=] [text=] +.B [ref=] [sleeptime=] [matched=] +.B [unsolicited=[:]] [flags=[\{pre|post\}\-]disconnect[,...]] +.RS +A dynamically generated entry, located below \fBretcode\-parent\fP. +The \fBerrCode\fP is the number of the response code; +it can be in any format supported by +.BR strtol (3). +The optional \fBoplist\fP is a list of operations that cause +response code generation; if absent, all operations are affected. +The \fBmatched\fP field is the matched DN that is returned +along with the error, while the \fBtext\fP field is an optional +diagnostics message. +The \fBref\fP field is only allowed for the \fBreferral\fP +response code. +The \fBsleeptime\fP field causes +.BR slapd (8) +to sleep the specified number of seconds before proceeding +with the operation. +The \fBunsolicited\fP field can be used to cause the return +of an RFC 4511 unsolicited response message; if \fBOID\fP +is not "0", an extended response is generated, with the optional +\fBdata\fP appended. +If \fBflags\fP contains \fBdisconnect\fP, or \fBpre\-disconnect\fP, +.BR slapd (8) +disconnects abruptly, without notice; \fBpost\-disconnect\fP +causes disconnection right after sending response as appropriate. +.RE +.TP +.B retcode\-indir +Enables exploitation of in-directory stored errAbsObject. +May result in a lot of unnecessary overhead. +.TP +.B retcode\-sleep [\-] +Defines a sleep time in seconds that is spent before actually handling +any operation. +If negative, a random time between 0 and the absolute value of the argument +is used. + +.SH SCHEMA +The +.B retcode +overlay utilizes the "return code" schema described herein. +This schema is specifically designed for use with this +overlay and is not intended to be used otherwise. +It is also noted that the schema described here is +.I a work in +.IR progress , +and hence subject to change without notice. +The schema is loaded automatically by the overlay. + +The schema includes a number of object classes and associated +attribute types as described below. + +.LP +The error code: +.RS 4 +( 1.3.6.1.4.1.4203.666.11.4.1.1 + NAME ( 'errCode' ) + DESC 'LDAP error code' + EQUALITY integerMatch + ORDERING integerOrderingMatch + SYNTAX 1.3.6.1.4.1.1466.115.121.1.27 + SINGLE\-VALUE ) +.RE +.LP +The operations that trigger the response code: +.RS 4 +( 1.3.6.1.4.1.4203.666.11.4.1.2 + NAME ( 'errOp' ) + DESC 'Operations the errObject applies to' + EQUALITY caseIgnoreMatch + SUBSTR caseIgnoreSubstringsMatch + SYNTAX 1.3.6.1.4.1.1466.115.121.1.15 ) +.RE +.LP +The text message: +.RS 4 +( 1.3.6.1.4.1.4203.666.11.4.1.3 + NAME ( 'errText' ) + DESC 'LDAP error textual description' + EQUALITY caseIgnoreMatch + SUBSTR caseIgnoreSubstringsMatch + SYNTAX 1.3.6.1.4.1.1466.115.121.1.15 + SINGLE\-VALUE ) +.RE +.LP +The sleep time before the response is actually returned to the client: +.RS 4 +( 1.3.6.1.4.1.4203.666.11.4.1.4 + NAME ( 'errSleepTime' ) + DESC 'Time to wait before returning the error' + EQUALITY integerMatch + SYNTAX 1.3.6.1.4.1.1466.115.121.1.27 + SINGLE\-VALUE ) +.RE +.LP +The matched DN returned to the client: +.RS 4 +( 1.3.6.1.4.1.4203.666.11.4.1.5 + NAME ( 'errMatchedDN' ) + DESC 'Value to be returned as matched DN' + EQUALITY distinguishedNameMatch + SYNTAX 1.3.6.1.4.1.1466.115.121.1.12 + SINGLE\-VALUE ) +.RE +.LP +The OID to be returned as extended response OID +in RFC 4511 unsolicited responses +("0" generates a regular response with msgid set to 0): +.RS 4 +( 1.3.6.1.4.1.4203.666.11.4.1.6 + NAME ( 'errUnsolicitedOID' ) + DESC 'OID to be returned within unsolicited response' + EQUALITY objectIdentifierMatch + SYNTAX 1.3.6.1.4.1.1466.115.121.1.38 + SINGLE\-VALUE ) +.RE +.LP +The octet string to be returned as extended response data +in RFC 4511 unsolicited response: +.RS 4 +( 1.3.6.1.4.1.4203.666.11.4.1.7 + NAME ( 'errUnsolicitedData' ) + DESC 'Data to be returned within unsolicited response' + SYNTAX 1.3.6.1.4.1.1466.115.121.1.40 + SINGLE\-VALUE ) +.RE +.LP +If TRUE, +.BR slapd (8) +disconnects abruptly without notice;
