-  Takes a quote-enclosed comma-separated string of one or more LDAP servers,
-  each in ``host:port`` format. {{program}} executes LDAP operations against

-  authorized to perform on a given database. 
+  The LDAP server against which the {{program}} executes LDAP operations
+  against to authenticate users or determine what actions a user is authorized
+  to perform on a given database. If the LDAP server specified has any
+  replicated instances, you may specify the host and port of each replicated
+  server in a comma-delimited list.
+  
+  If your LDAP infrastrucure partitions the LDAP directory over multiple LDAP
+  servers, specify *one* LDAP server any of its replicated instances to
+  {{role}}. MongoDB supports following LDAP referrals as defined in `RFC 4511
+  4.1.10 <https://www.rfc-editor.org/rfc/rfc4511.txt>`_. Do not use {{role}}
+  for listing every LDAP server in your infrastucture.
   
   This setting can be configured on a running {{program}} using 
   :dbcommand:`setParameter`.
