The next line specifies a list of options for this search object. This is typically used to limit the types of entries returned to those containing a specific object class. Note that parentheses may be unbalanced here, since this is a filter prefix, not an entire filter. The next line specifies an LDAP attribute to retrieve to help the user choose when several entries match the search terms specified. The next line specifies the scope of the LDAP search to be performed.
Acceptable values are subtree, onelevel, and base.
Each line represents one method of searching. In this example, there are three ways of searching - by Common Name, by Surname, and by Business Phone number. The first field is the text which should be displayed to user. The second field is the attribute which will be searched. If blank, the client software should use the default values above.
