See COPYRIGHT/LICENSE. +.\" $OpenLDAP$ +.SH NAME +slapo\-constraint \- Attribute Constraint Overlay to slapd +.SH SYNOPSIS +ETCDIR/slapd.conf +.SH DESCRIPTION +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. +.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. +.LP +It constrains only LDAP \fIadd\fP, \fImodify\fP and \fIrename\fP commands +and only seeks to control the \fIadd\fP and \fIreplace\fP values +of \fImodify\fP and \fIrename\fP requests. +.LP +No constraints are applied for operations performed with the +.I relax +control set. +.SH CONFIGURATION +This +.B slapd.conf +option applies to the constraint overlay. +It should appear after the +.B overlay +directive. +.TP +.B constraint_attribute [,...] [ [...]] +Specifies the constraint which should apply to the comma-separated +attribute list named as the first parameter. +Six types of constraint are currently supported - +.BR regex , +.BR negregex , +.BR size , +.BR count , +.BR uri , +and +.BR set . + +The parameter following the +.B regex +or +.B negregex +type is a Unix style regular expression (See +.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. + +The parameter following the +.B set +type is a string that is interpreted according to the syntax in use +for ACL sets. This allows one to construct constraints based on the contents +of the entry. + +The +.B size +type can be used to enforce a limit on an attribute length, and the +.B count +type limits the number of values of an attribute. + +Extra parameters can occur in any order after those described above. +.RS +.TP +.B : restrict= +.RE + +.RS +This extra parameter allows one to restrict the application of the corresponding +constraint only to entries that match the +.IR base , +.I scope +and +.I filter +portions of the LDAP URI. +The +.IR base , +if present, must be within the naming context of the database. +The +.I scope +is only used when the +.I base +is present; it defaults to +.BR base . +The other parameters of the URI are not allowed. +.RE + +.LP +Any attempt to add or modify an attribute named as part of the +constraint overlay specification which does not fit the +constraint listed will fail with a +LDAP_CONSTRAINT_VIOLATION error. +.SH EXAMPLES +.LP +.RS +.nf +overlay constraint +constraint_attribute jpegPhoto size 131072 +constraint_attribute userPassword count 3 +constraint_attribute mail regex ^[[:alnum:]]+@mydomain.com$ +constraint_attribute mail negregex ^[[:alnum:]]+@notallowed.com$ +constraint_attribute title uri + ldap:///dc=catalog,dc=example,dc=com?title?sub?(objectClass=titleCatalog) +constraint_attribute cn,sn,givenName set + "(this/givenName + [ ] + this/sn) & this/cn" + restrict="ldap:///ou=People,dc=example,dc=com??sub?(objectClass=inetOrgPerson)" +.fi + +.RE +A specification like the above would reject any +.B mail +attribute which did not look like +.BR "@mydomain.com" +or that looks like +.BR "@notallowed.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. (Note that the +"dc=catalog,dc=example,dc=com" subtree ought to reside +in a separate database, otherwise the initial set of +titleCatalog entries could not be populated while the +constraint is in effect.) +Finally, it requires the values of the attribute +.B cn +to be constructed by pairing values of the attributes +.B sn +and +.BR givenName , +separated by a space, but only for entries derived from the objectClass +.BR inetOrgPerson . +.RE +.SH FILES +.TP +ETCDIR/slapd.conf +default slapd configuration file +.SH SEE ALSO +.BR slapd.conf (5), +.BR slapd\-config (5), +.SH ACKNOWLEDGEMENTS +This module was written in 2005 by Neil Dunbar of Hewlett-Packard and subsequently +extended by Howard Chu and Emmanuel Dreyfus. +.so ../Project -- cgit v1.2.3
