The file /etc/ldap/ldapfilter.conf contains information used by the LDAP get filter routines (see ldap-getfilter(3)?). Blank lines and lines that have a first character of `#' are treated as comments and ignored. The configuration information consists of lines that contain one, two, three, four, or five tokens. Tokens are separated by white space, and double quotes ` __
The file consists of a sequence of one or more filter sets. A filter set begins with a line containing a single token called a tag. The tag is used in the ldap_getfirstfilter(3)? call to select the filter set.
The filter set consists of a sequence of one or more filter lists. The first line in a filter list must contain four or five tokens: the value pattern, the delimiter list, a filter template, a match description, and an optional search scope. The value pattern is a regular expression that is matched against the value passed to the ldap_getfirstfilter(3)? call to select the filter list.
The delimiter list is a list of characters (in the form of a single string) that are used to break the value into distinct words.
The filter template is used to construct an LDAP filter (it is described further below)
The match description is returned to the called along with a filter as a piece of text that can be used to describe the sort of LDAP search that took place. It should correctly compete both of the following phrases: match description match was found for... match description matches were found for....''
The search scope is optional, and should be one of search scope is not provided, the default is ''
The remaining lines of the filter list should contain two or three tokens, a filter template, a match description and an optional search scope (as described above).
The filter template is similar in concept to a printf(3) style format string. Everything is taken literally except for the character sequences:
The following ldap filter configuration file contains two filter sets (finger and go500gw onelevel), each of which contains four filter lists.
# finger The call ldap_getfirstfilter( lfdp, will return an LDAPFiltInfo structure with the lfi_filter member containing the string (cn=m* smith) with the lfi_desc member containing the string first initial, and lfi_scope containing the value LDAP_SCOPE_SUBTREE.
