/**
* Address book backend for LDAP server
*
* An array with the following elements must be passed to
* the class constructor (elements marked ? are optional)
*
* Main settings:
* <pre>
* host => LDAP server hostname, IP-address or any other URI compatible
* with used LDAP library.
* base => LDAP server root (base dn). Empty string allowed.
* ? port => LDAP server TCP port number (default: 389)
* ? charset => LDAP server charset (default: utf-8)
* ? name => Name for LDAP server (default "LDAP: hostname")
* Used to tag the result data
* ? maxrows => Maximum # of rows in search result
* ? timeout => Timeout for LDAP operations (in seconds, default: 30)
* Might not work for all LDAP libraries or servers.
* ? binddn => LDAP Bind DN.
* ? bindpw => LDAP Bind Password.
* ? protocol => LDAP Bind protocol.
* </pre>
* Advanced settings:
* <pre>
* ? filter => Filter expression to limit ldap search results.
* You can use this to *limit* the result set, based on specific
* requirements. The filter must be enclosed in parentheses, e.g.:
* '(objectclass=mailRecipient)'
* or '(&(objectclass=mailRecipient)(obectclass=myCustomClass))'
* The default value is empty.
*
* ? search_expression => Custom expression to expand ldap searches.
* This can help *expand* the result set, because of hits in more
* LDAP attributes. It must be a printf()-style string with either
* one placeholder '%s', or, if you want to repeat the expression
* many times, '%1$s'. The default value is:
* '(|(cn=*%1$s*)(mail=*%1$s*)(sn=*%1$s*))'
* that is, the search expression is search in the fields cn (common
* name), sn (surname) and mail.
*
* ? limit_scope => Limits scope to base DN (Specific to Win2k3 ADS).
* ? listing => Controls listing of LDAP directory.
* ? writeable => Controls write access to address book
* ? search_tree => Controls subtree or one level search.
* ? starttls => Controls use of StartTLS on LDAP connections
* </pre>
* NOTE. This class should not be used directly. Use addressbook_init()
* function instead.
