AXIS 700 User’s Manual Appendix B: LDAP 79
The attribute types are used to create search filters. There are six types
of basic search filters and the syntax of the filters is in the
<attribute><operator><value> format. Complex search filters can
easily be constructed by combining these basic search filters and other
complex filters using the Boolean operations AND, OR and NOT.
The six basic filter components are presented in the table belo:
