slapo-constraint — Attribute Constraint Overlay to slapd
ETCDIR/slapd.conf
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.
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.
This slapd.conf
option applies to the constraint overlay. It should appear
after the overlay
directive.
Specifies the constraint which should apply to the
attribute named as the first parameter. At the moment
only one type of constraint is supported - regex.
The parameter
following the regex type is a Unix style
regular expression (See 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.
