# vrfydmn_ldap(5) Manual Page

## NAME

vrfydmn_ldap - lookup RFC5322 From:-addresses in an LDAP database.

## SYNOPSIS

vrfydmn -l ldap:///etc/vrfydmn/ldap.cfg

## DESCRIPTION

vrfydmn uses lists and tables to lookup mail related informations. A lookup tables may be an LDAP database.

In order to use LDAP lookups, specify a path to a file holding LDAP connection and query configuration. The path must be given when vrfydmn is invoked on command line:

vrfydmn -l ldap:///etc/vrfydmn/ldap.cfg

## OPTIONS

base (default: None)

  The RFC2253 base DN at which to conduct the search, e.g.

      base = ou=maildomains,dc=example,dc=com

bindmethod (default: None)

  The method used when binding to the LDAP server. Valid options are simple or sasl.

cacert (default: None)

  Specifies the file that contains certificates for all of the Certificate Authorities the client will recognize.

      cacert = /etc/ssl/certs/cacerts.pem

cert (default: None)

  Specifies the file that contains the client certificate.

      cert = /etc/ssl/certs/mail.example.com-crt.pem

filter (default: None)

  The RFC2254 filter used to search the directory, e.g.

      filter = (domain=*)

host (default: None)

  The name of the host running the LDAP server, e.g.

      host = 127.0.0.1, ldap.example.com

key (default: None)

  Specifies the file that contains the private key that matches the certificate stored in the cert file. Currently, the private key must not be protected with a password, so it is of critical importance that the key file is protected carefully.

      key = /etc/ssl/private/mail.example.com-key.pem

reqcert (default: demand)

  Specifies what checks to perform on server certificates in a TLS session, if any. The <level> can be specified as one of the following keywords:

  never

    The client will not request or check any server certificate.

  allow

    The server certificate is requested. If no certificate is provided, the session proceeds normally. If a bad certificate is provided, it will be ignored and the session proceeds normally.

  try

    The server certificate is requested. If no certificate is provided, the session proceeds normally. If a bad certificate is provided, the session is immediately terminated.

  demand

    The server certificate is requested. If no certificate is provided, or a bad certificate is provided, the session is immediately terminated. This is the default setting.

result_attrs (default: None)

  The name of the attribute whose value the query should return.

      result_attrs = domain

saslmech (default: None)

  The mechanism outgoing’s LDAP client should use, when it sasl-binds to the remote LDAP server. Valid options are currently PLAIN or EXTERNAL.

scope (default: None)

  The LDAP search scope: sub, base, or one.

usetls (default: No)

  A Boolean option to enable or disable usage of TLS when connecting to the LDAP server. Valid options are Yes or No.
