...
aci: (target_rule)(version 3.0; acl "ACL_name"; permission_rule bind_rules;)

Target Rules

Syntax: 

keyword comparison_operator "expression"

Examples:

Description Target Rule
Subtree target = "ldap:///dc=example,dc=com"
Wildcard target = "ldap:///uid=*,dc=example,dc=com"
Specific attribute targetattr = "userPassword"
Search filter targetfilter = "(uid=*)"

Permissions

Syntax: 

permission (rights)

Examples:

Description Permission
Granting rights allow (search, read)

Examples:

Description Bind Rule
Anonymous users userdn = "ldap:///anyone"
Authenticated users userdn = "ldap:///all"
Self userdn = "ldap:///self"
Children userdn = "ldap:///parent"
Specific user userdn = "ldap:///uid=admin,ou=people,dc=example,dc=com"
