The following list describes changes in the use of the Lightweight Directory Access Protocol (LDAP) with sendmail.
LDAPROUTE_EQUIVALENT() and LDAPROUTE_EQUIVALENT_FILE() permit you to specify equivalent host names, which are replaced by the masquerade domain name for LDAP routing lookups. For more information, refer to /etc/mail/cf/README.
As noted in the Release Notes that are part of the sendmail distribution at ftp://ftp.sendmail.orgftp://ftp.sendmail.org, the LDAPX map has been renamed to LDAP. Use the following syntax for LDAP.
Kldap ldap options
This release supports the return of multiple values for a single LDAP lookup. Place the values to be returned in a comma-separated string with the –v option, as is shown.
Kldap ldap -v"mail,more-mail"
If no LDAP attributes are specified in an LDAP map declaration, all attributes that are found in the match are returned.
This version of sendmail prevents commas in quoted key and value strings in the specifications of the LDAP alias file from dividing a single entry into multiple entries.
This version of sendmail has a new option for LDAP maps. The option –Vseparator enables you to specify a separator so that a lookup can return both an attribute and a value that are separated by the relevant separator.
In addition to using the %s token to parse an LDAP filter specification, you can use the new token, %0, to encode the key buffer. The %0 token applies a literal meaning to LDAP special characters.
The following example shows how these tokens differ for a “*” lookup.
