  LDAP Search 
This  option is to  narrow  the  LDAP  search  scope.  Enter  the  LDAP 
search base in the Description field. It could be the same or different 
from the Base in LDAP configuration under Advanced Settings. The 
Base in LDAP configuration will be used if the Description field is left 
blank. Enter the LDAP Name/Number filter in the Value field. 
For example: 
If users set MPK 1 as “LDAP Search” for “Account 1”, and set filters: 
Description -> ou=video,ou=SZ,dc=grandstream,dc=com 
Value -> sn=Li 
Since  the  Base  for  LDAP  server  configuration  is

LDAP search scope. “sn=Li” is the example to filter the last name.
