LDAP Server 
 
The  UCM6200  has  an  embedded  LDAP  server  for  users  to  manage  corporate  phonebook  in  a  centralized 
manner. 
 
•  By  default,  the  LDAP  server  has  generated  the  first  phonebook  with  PBX  DN  "ou=pbx,dc=pbx,dc=com" 
based on the UCM6200 user extensions already. 
•  Users could add new phonebook with a different Phonebook DN for other external contacts. For example, 
"ou=people,dc=pbx,dc=com". 
•  All the phonebooks in the UCM6200 LDAP server have the same Base DN "dc=pbx,dc=com". 
 
Term Explanation:   
cn= Common Name 
ou= Organization Unit 
dc= Domain Component 
These are all parts of the LDAP data Interchange Format, according to RFC 2849, which is how the LDAP tree 
is filtered. 
 
If users have the Grandstream phone provisioned by the UCM6200, the LDAP directory will be set up on the 
phone and can be used right away for users to access all phonebooks. 
Additionally, users could manually configure the LDAP client settings to manipulate the built-in LDAP server on 
the UCM6200. If the UCM6200 has multiple LDAP phonebooks created, in the LDAP client configuration, users 
could use "dc=pbx,dc=com" as Base DN to have access to all phonebooks on the UCM6200 LDAP server, or 
use  a  specific  phonebook  DN,  for  example  "ou=people,dc=pbx,dc=com",  to  access  to  phonebook  with 
Phonebook DN "ou=people,dc=pbx,dc=com " only. 
 
UCM can also act as a LDAP client to download phonebook entries from other LDAP server. 
To access LDAP server and client settings, go to Web GUI->Settings->LDAP Server.
