I would like to learn, based on the schemas in use, whether I can expect a single value in any given field as opposed to the possibility of multiple values. E.g. I would expect only one dn. I would also like to learn what other assumptions I can make of the data.

I have found everything I ever needed to know about LDAP with these lines of code, especially the print_r and is_array bits.

	$ldapserver ="ldaps://ldap.uvm.edu" ;
	$dnstring ="ou=People,dc=uvm,dc=edu" ;
	$filter ="(uid=$_POST['uid'])" ;
	$ds =ldap_connect ($ldapserver );
	if ( $ds ) {
	
		// this is an anonymous bind - just to search
		$r =ldap_bind ($ds);
	
		//perform the search
		$sr =ldap_search ($ds ,$dnstring ,$filter);
	
		//if we couldn't find them, return false
		if(! ldap_count_entries ($ds ,$sr )) {
			print "No user {$_SERVER['REMOTE_USER']}" ;
			exit;
		}
		//retrieve records found by the search
		$info =ldap_get_entries ($ds ,$sr );
		print "<pre>\n";
		// This tells you everything you need to know...
		print_r($info);
		print "\n\n";
		foreach ($info[0] as $entry) {
			if (!is_array($entry)) {
				// single attribute
				print "LDAP field name for above: $entry\n\n";
			} else {
				// multiple attributes
				foreach($entry as $index=>$subfield) {
					print "entry $index : $subfield\n";
				}
			}
		}
		ldap_close ($ds );
	}
