.SH NAME
slapo\-ciboolean \- enable support for case-insensitive boolean values
.SH SYNOPSIS
By default
.BR slapd (8)
is strictly compliant with
.B RFC4517
and the only accepted values for a Boolean attribute are
.B TRUE
and
.B FALSE.
This module allows for case-insensitive comparison and syntax-checking.
.SH DESCRIPTION
The
.B ciboolean
module to
.BR slapd (8)
allows Boolean-type attributes to have values such as
.B True, False, true, false,
and any other combination of upper and lower-case values. Comparison is also case-insensitive, so a search filter of
.B (attribute=false)
will return objects with all versions of
.B FALSE.
When the module is loaded, it installs a new syntax-checker and a new normalizer in the
.B Boolean
syntax.
.SH CONFIGURATION
The
.B ciboolean
module does not have any configuration directives. To enable it, instruct the server to load it with the
.B moduleload
directive in
.B slapd.conf:
.TP
.B moduleload /usr/local/libexec/openldap/ciboolean.la
.SH LIMITATIONS
Adding a normalizer to the syntax changes value storage format in most backend types.
Removing the
.B ciboolean
module from
.BR slapd(8)
configuration will not automatically convert any non-standard values to
.B TRUE
or
.B FALSE,
or update value storage format. Therefore, if
.B ciboolean
is added or removed in configuration, all databases that have been in use before the change need to be fully reloaded to ensure correct operation, including
.B cn=config.
.SH FILES
.TP
ETCDIR/slapd.conf
default slapd configuration file
.TP
ETCDIR/slapd.d
default slapd configuration directory
.SH SEE ALSO
.BR slapd-config (5),
.BR slapd.conf (5),
.BR slapd (8)
.SH ACKNOWLEDGEMENTS
This module was developed in 2022 by Nadezhda Ivanova for Symas Corp.
