Searching Multi-Valued Attributes

During a search, Directory Server does not necessarily return multi-valued attributes in sorted order. For example, suppose you want to search for configuration attributes on cn=config requiring that the server be restarted before changes take effect.

ldapsearch -h myServer -p 5201 -D cn=admin,cn=Administrators,cn=config -w -
 -b cn=config "(objectclass=*)" nsslapd-requiresrestart

The following result is returned:

dn: cn=config
nsslapd-requiresrestart: cn=config:nsslapd-port
nsslapd-requiresrestart: cn=config:nsslapd-secureport
nsslapd-requiresrestart: cn=config:nsslapd-plugin
nsslapd-requiresrestart: cn=config:nsslapd-changelogdir
nsslapd-requiresrestart: cn=config:nsslapd-changelogsuffix
nsslapd-requiresrestart: cn=config:nsslapd-changelogmaxentries
nsslapd-requiresrestart: cn=config:nsslapd-changelogmaxage
nsslapd-requiresrestart: cn=config:nsslapd-db-locks
nsslapd-requiresrestart: cn=config:nsslapd-return-exact-case
nsslapd-requiresrestart: cn=config,cn=ldbm database,cn=plugins,
  cn=config:nsslapd-allidsthreshold
nsslapd-requiresrestart: cn=config,cn=ldbm database,cn=plugins,
  cn=config:nsslapd-dbcachesize
nsslapd-requiresrestart: cn=config,cn=ldbm database,cn=plugins,
  cn=config:nsslapd-dbncache
nsslapd-requiresrestart: cn=config,cn=ldbm database,cn=plugins,
  cn=config:nsslapd-directory
nsslapd-requiresrestart: cn=encryption,cn=config:nssslsessiontimeout
nsslapd-requiresrestart: cn=encryption,cn=config:nssslclientauth
nsslapd-requiresrestart: cn=encryption,cn=config:nssslserverauth
nsslapd-requiresrestart: cn=encryption,cn=config:nsssl2
nsslapd-requiresrestart: cn=encryption,cn=config:nsssl3
...

As shown here, the nsslapd-requiresrestart attribute takes multiple values. These values are not, however, in sorted order. If you develop an application that requires multi-valued attributes in sorted order, make sure that your application performs the sort.
