Select the Override System Settings check boxes to enable their related fields.
Base DN
The base organizational unit where the users are defined. Contact your directory administrator for the correct Base DN value.  (The Base DN value entered here can be overridden in a local user host LDAP mailbox.)
The examples the table below show sample base organizational units for the supported directory types. 
Directory Type Example Base DN
Active Directory OU=Employees,DC=company,DC=com
Apache Directory Services OU=Users,DC=example,DC=com
Lotus Domino O=SCNotes
Novell eDirectory O=Company Organization
DirX ou=Users,o=Company
Search filter
Optional. Used to limit the amount of information returned from the LDAP server when many users are defined. A more restrictive filter can be specified as a comma separated list. If necessary, contact your directory administrator to determine the appropriate attributes and values. You can override the value entered here in a local user host LDAP mailbox.
The following table contains example lists with sample attribute names and values.
Search Filter Description
department=EDI Limits the search to entries that have the attribute, department, with a value of EDI.
department=EDI,group=administrators Limits the search to entries that must match two attributes. The user must be in the EDI department and in the administrators group.
department=EDI,telephoneNumber=800* Limits search to EDI department members with a telephone number starting with 800.
objectclass=person Limit the search to entries that are people if the Base DN contains other entries (for example, computers) and people.
!(userAccountControl:1.2.840.113556.1.4.803:=2) Excludes disabled accounts - in Active Directory, if an account is disabled, bit 0x02 in the userAccountControl attribute value is on.  1.2.840.113556.1.4.803 is the rule object ID (ruleOID) for the LDAP bitwise AND operator.
