.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
The constraint overlay is used to ensure that attribute values match
some constraints beyond basic LDAP syntax. Attributes can
have multiple constraints placed upon them, and all must be satisfied
when modifying an attribute value under constraint.

.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.
Two types of constraint are currently supported -
.B regex
and
.BR uri .
The parameter following the
.B
regex
.B regex
type is a Unix style regular expression (See
.B
regex(7))
.BR regex (7)
). The parameter following the
.B uri
type is an LDAP URI. The URI will be evaluated using an internal search.
It must not include a hostname, and it must include a list of attributes
to evaluate.
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
constraint overlay specification which does not fit the
constraint listed will fail with a
LDAP_CONSTRAINT_VIOLATION error.

.RS
.nf
overlay constraint
constraint_attribute mail regex ^[:alnum:]+@mydomain.com$
constraint_attribute title uri
ldap:///dc=catalog,dc=example,dc=com?title?sub?(objectClass=titleCatalog)
.fi
A specification like the above would reject any
.B
mail
.B mail
attribute which did not look like
.B
<alpha-numeric string>@mydomain.com
It would also reject any
.B title
attribute whose values were not listed in the
.B title
attribute of any
.B titleCatalog
entries in the given scope.
