[FIXED HUDSON-2600] In 1.253 the default "ou=groups" was removed so a blank value may

be used to search from rootDN.. now updating help file to reflect that change,
recommending "ou=groups" as most common setting.

 <div>
     One of the searches Hudson does on LDAP is to locate the list of groups for a user.
 
-    <p>
-    This field determines the query to be run to identify the organizational unit that contains groups. The query is
-    almost always <tt>"ou=groups"</tt>, so in most cases you should leave this field empty and let this default kick in.
