Enter a filter. The filter can contain a maximum of 1024 UTF-8 characters. Enclose the filter text within parentheses ().
The LDAP filter filters the results of LDAP searches. LDAP users that match the filter get imported into the Cisco Unified Communications Manager database, while LDAP users that do not match the filter do not get imported.
The filter text that you enter must comply with the regular LDAP search filter standards specified in RFC 4515. It is recommended that you verify the LDAP search filter against the LDAP directory/searchbase by using the ldapsearch command.
You apply LDAP filters to LDAP directories. For more information, see the LDAP directory setup. You can apply an LDAP filter to multiple LDAP directories, and to all LDAP directory types for which the filter is valid.
