.TH SLAPO-CONSTRAINT 5 "RELEASEDATE" "OpenLDAP LDVERSION"

|
|
.SH NAME
|
|
slapo-constraint \- Attribute Constraint Overlay to slapd
|
|
.SH SYNOPSIS
|
|
ETCDIR/slapd.conf
|
|
.SH DESCRIPTION
|
|
The constraint overlay is used to enforce a regular expression
|
|
constraint on all values of specified attributes. Attributes can
|
|
have multiple constraints placed upon them, and all must be satisfied
|
|
when modifying an attribute value under constraint.
|
|
.LP
|
|
This overlay is intended to be used to force syntactic regularity upon
|
|
certain string represented data which have well known canonical forms,
|
|
like telephone numbers, post codes, FQDNs, etc.
|
|
.SH CONFIGURATION
|
|
This
|
|
.B slapd.conf
|
|
option applies to the constraint overlay.
|
|
It should appear after the
|
|
.B overlay
|
|
directive.
|
|
.TP
|
|
.B constraint_attribute <attribute_name> <type> <value>
|
|
Specifies the constraint which should apply to the attribute named as
|
|
the first parameter.
|
|
At the moment only one type of constraint is supported -
|
|
.B
|
|
regex.
|
|
The parameter following the
|
|
.B
|
|
regex
|
|
type is a Unix style regular expression (See
|
|
.B
|
|
regex(7))
|
|
|
|
Any attempt to add or modify an attribute named as part of the
|
|
constraint overlay specification which does not fit the regular
|
|
expression constraint listed will fail with a
|
|
LDAP_CONSTRAINT_VIOLATION error.
|
|
.SH EXAMPLES
|
|
.B
|
|
constraint_attribute mail regex ^[:alnum:]+@mydomain.com$
|
|
|
|
A specification like the above would reject any
|
|
.B
|
|
mail
|
|
attribute which did not look like
|
|
.B
|
|
<alpha-numeric string>@mydomain.com
